Marijuana plants can be males, females or hermaphrodites (both sexes in the same plant). Female plants produce buds, the richest part of the plant in When it comes to harvesting home-grown marijuana, female plants are the name of the game. Not only do female plants produce the coveted buds needed for medicinal purposes, but they also have higher potency and THC content compared to their…
How to distinguish marijuana males from females
Marijuana (cannabis sativa sp.) is a dioecious or unisexual plant, what means that it produces male and female flowers in different individuals, although we can find both types of flowers in hermaphrodite plants. We call males those plants that produce male flowers, and females those producing female flowers.
Male and female cannabis flowers
Marijuana males flower producing small bell-shaped clusters, that hang down and open releasing the pollen, while females produce tear-shaped calyxes with two pistils – usually white – that group together forming what we call buds.
When to determine the sex of marijuana plants?
Male and female cannabis plants
Generally, cannabis plants start flowering when nights – dark periods – are longer, which is a sign to show their sex and start blooming. Actually, marijuana plants reach their sexual maturity between 6-8 weeks after seed germination , regardless of the photoperiod.
It is this fact what can help us to determine the sex of our marijuana plants without the need to make cuttings or change the photoperiod, what could strees our young plants.
As we mentioned before, when plants are about 2 months old – when they have 5 or 6 internodes – they are sexually mature, which is to say, they have set their sex. In some cases – most of them produced by stress – plants will show both sexes, being what we call hermaphrodites, but generally at this moment plants show their true sex, that will mantain for their entire life cycle.
This technique of premature detection of the sex needs a little practice, but once mastered it will allow us to determine the sex of our cannabis plants at a very early stage.
Sexing marijuana from cuttings
Early flowering of a female cannabis plant
If we can’t sex our plants with this technique, we can take a cutting from each of our marijuana plants and flower it in a growing tent – 12 hours of light/darkness photoperiod – what will force it to flower and show its sex, that will be exactly the same as its mother plant.
What we don’t recommend at all is forcing the flowernig of mother plants for a few days/weeks and once they show their sex placing them again with a growing photoperiod (18 hours of light/6 hours of darkness), since this will produce major hormonal changes inside the plants, being an easy way to stress them – what will improve the chances to get hermaphrodite plants.

Comments in “How to distinguish marijuana males from females” (49)
I planted 19 plants knowing I would end up with many males. All the plants were planted in the same soil mixture. Eight plants turned out to be male, (which I pulled and tossed) What has stunned me is that over 1/2 of what are left have turned Hermaphroditic. I have gone out the last seven days at least twice a day to tweeze off all the male buds at the branches and now some showing up in the flowers. I believe I have gotten most of the male buds stripped from the plants. So my question is; In doing so and the female flowers grow to full maturity, will the plants have been hurt by my having yanked off all those male flowers? Many Thanks
Tim Alchimia 2022-05-30
Hi, thanks for your comment. There’s no real problem with removing male flowers from the female buds, the plants shouldn’t suffer from it, but it’s a lot of work because presumably, they’ll keep appearing as the plants mature. As long as you get them all before they open and spill pollen, there’s no reason for any issues with the final product. However, with so many plants showing hermaphrodite traits, personally, I’d be looking for the root cause of the problem. The genetics are evidently prone to intersex behaviour, however, there’s usually some kind of stress that provokes the appearance of male flowers, be it high temperatures, low humidity, over or under-feeding, too intense a light, or more usually, some light contamination or light leak that is interrupting the dark period needed for flowering to develop normally. Have a good look at the growing conditions and try and work out what it could be and you could save yourself a lot of time and effort spent removing male flowers and solve the problem for the future. Check out our article on hermaphrodites in cannabis for more info. I hope that helps, best wishes and happy growing!
Very useful information. I am a beginner l was gifted 2 plants, a boy and a girl. And both are thriving.
Tim Alchimia 2021-10-29
Hi and thanks for your comment. Glad to hear your plants are thriving. However, unless your plan is to make seeds, you’ll have no need for the male plant at all. If you’re growing for the smoke, get rid of the male ASAP before he pollinates the female and your buds end up full of seeds. All the best and happy growing!
Wife’s ass 2021-08-17
Hi my question is when you have a male plant do you pull it or just continue to let it grow will form buds can you help me out
Tim Alchimia 2021-08-17
Hi and thanks for your question. You should pull out the male plants and destroy them unless you specifically want to make seeds. The male plants will not produce anything that’s smokeable, just lots of pollen for pollinating female plants, which is great if you’re a breeder but if you just want a smoke then the last thing you need is to fill your buds with seeds! I hope that’s cleared up any confusion. Best wishes and happy growing!
I sent some pictures to the email address. Hoping someone can help tell me if it is male or female soon. Thanks.
Tim Alchimia 2021-07-23
Hi, yes we got the photos, thanks! I’ve looked at them and I’m afraid that it’s still a little too early to tell which sex the plant is. Sometimes the pre-flowers can be extremely misleading. I’d give it a week or two and check again. Also, don’t forget to check the nodes further up the plant, I’ve even been finding some plants with their pre-flowers right up at the 8th node. I hope that helps. Best wishes and happy growing!
Steven Is an Alchimia client 2021-06-22
Hi Tim, I sent some pictures to you, was wondering can you help me determine if they are male or female. Thanks
Tim Alchimia 2021-06-23
Hi Steven, thanks for your comment. I replied to your email on Monday, you should have the reply in your inbox but I’ll explain here too. The plants in the photos were a little too young to determine sex yet. Wait a week or two and take some close-up photos, focusing particularly on the area around the 5th and 6th nodes, which is where the pre-flowers tend to first appear. Then I should be able to help you. All the best, happy growing!
I think have a hermaphrode plant on my hands. Do I just toss it? If it pollinates itself it will only produce hermaphrode seeds no?
Tim Alchimia 2021-05-04
Hi Nicole, thanks for your comment. What you do with a hermaphrodite plant will depend on a few different things. firstly, do you have more plants growing that could get pollinated by this plant? If you’re only growing the one plant then you can relax a bit as there’s not so much at stake – it’s different when you have an entire room of plants that could be spoiled by just one plant. Secondly, consider the number of hermie flowers on the plant – often it’s only a couple of male flowers in the lower branches that are relatively easy to remove and keep an eye on for the rest of the flowering period just in case more of them show themselves. If, however, you’re seeing male flowers all over and in relatively large numbers, then maybe it’s time to throw it out. I mean, you could always just pick the seeds out when you smoke the bud, but if you miss one the whole joint will taste dreadful! The resulting seeds will definitely carry the hermaphrodite trait in their genes, although that’s not to say that each and every plant from them will be a hermie. but it’s much more likely. You can read more about the subject and what can provoke plants to show intersex traits in our related blog post. I hope that helps, best wishes and happy growing!

Hey . can u help me to do next steps ??
Tim Alchimia 2021-02-25
Hi Raj, how can we help you?
This is Bryan ( BAE ). I sent pics of the 3 plants to the email address!! Thanks
Tim Alchimia 2020-12-07
Hi Bryan, thanks for the email, it took a few days to find its way to my desktop but I’ve checked the photos and they all look like males to me, I can’t see any pistils, bracts or any other evidence of female flowers, just lots of pollen sacks. Sorry if that’s a disappointment to you, I hope you have better fortune next time. All the best and happy growing!
I have plants and not sure if they are males or females. Can I send you pics and see what your suggestion is? Thanks
Tim Alchimia 2020-11-30
Hi, thanks for your comment. You can send photos to [email protected] for the attention of Tim. Make sure that they are clear, well-lit and focussed pictures of the flower area, please. All the best and happy growing!
Hi, I’m having trouble deciding if a few of my plants are Male, I may just be in denial, if I send you a picture would you be able to help me identify if it’s a Male? Thanks so much
Tim Alchimia 2020-09-18
Hi Diane, thanks for your comment. You can send some photos (for the attention of Tim) to [email protected] and I’ll do my best to help you identify the sex of your plants. Best wishes and happy growing!
Sugar Cane 2020-07-25
Good day everyone, I just wanted to know which plant is the one we use for harvesting(smoking) male/female. It’s my first time growing so far so much fun ; )
Tim Alchimia 2020-07-27
Hi and thanks for the question. The female is the one with all the psychoactive properties and the one we harvest for use. I hope that helps, best wishes and happy growing!
Just want to say your article is as astonishing. The clearness to your submit is simply spectacular and that i coild suppose you are knowledgeable on this subject. Fine with your permission let me to grasp your feed to staay up to date with impending post. Thanks one million and please keep upp the gratifying work.
Tim Alchimia 2020-06-02
Hi Kevin, thanks so much for your kind words, they really do mean a lot to us. Best wishes and happy growing!
I have 5 plants 2 I believe are female because I’m seeing what looks like a leaf shaped tear drop all over there plant popping out from behind the stapules. however I have 2 more I thought were male cause at first glance the preflowers looked rounded. now they are getting bigger I’m noticing more of a point at the end looks like a ball with a pointed leaf right in front. havent found any on stems yet. I took clones of these 2 and am putting under 12/12. I’m still not seeing any white hairs though on the plants I have seen the pointed tear drop leaf like growth it’s been about 2 weeks now today just started week 7. any advice would b awesome I don’t want to risk pollination. I’m trying to start a perpetual grow so I want to find the best mother plant so I am hoping for as many females as possible choose from so any help and advice be awesome. I can send pics on e mail
Tim Alchimia 2020-05-05
Hey, thanks for your comment, don’t worry, it can be very confusing at first and some pre-flowers can be very confusing. In some cases what I thought were male flowers turned out to be a new branch sprouting from the node! Send pics to [email protected] and I’ll do what I can to help you out. Best wishes and happy growing!
2 part question. I’ve recently inherited a cannabis plant to grow and maintain for fun as a new hobby. I received two plants in one pot at about 7 in a half weeks? Being very new to this, how can I tell them apart if they’re male and female & should I separate them?
Tim Alchimia 2020-04-28
Hi T, thanks for your question! Firstly, yes, you should definitely separate the plants and put each one in its own container with some fresh soil. Do this carefully to avoid damaging the roots, which may be quite intermingled among themselves right now. As for sexing the plants, you’ll need to keep an eye out for any pre-flowers appearing at the nodes, the points where the leaves and branches join the main stem. These flowers tend to first appear anywhere between the 3rd and 5th or 6th nodes. Male flowers are shaped like a ball on a stick, protruding from the node. Once ready, the ball opens to reveal the stamen and anthers, yellow with pollen, hence the nickname “bananas”. Female pre-flowers are somewhat teardrop-shaped and sprout directly from the node itself. They’ll usually have a white hair or two (pistils) sticking out from the pointy end of the flower. The pictures in this article should be some help in that department. All the best with your plants, happy growing!
Kevin r 2020-04-23
I have a northern light that’s in three weeks of flower but they’re are some pollen coming out of it when i looked the flower was a teardrop but still has pollen coming out of it can u tell me anything differant
Tim Alchimia 2020-04-24
Hi Kevin, thanks for your comment. I can’t really be sure what’s happening here. Male flowers look like a ball on a stick, but they can sometimes have a teardrop shape to them. For them to produce pollen, however, this ball would need to open to expose the stamens and anthers, also known as “bananas” among weed-growers, from which the pollen falls. It’s not so easy to describe these things in words as it is to see them in pictures, so if you can, send me a clear, close-up photo of the suspicious flower to [email protected] and I’ll probably be able to help you out. All the best and happy growing!
Hi There I am new at this and just started watching a plant that I have inherited from a Friend for fun. They have been growing strong (There are three plants together in a pot) and as far as I can tell there are no Pollen Sacks. They actually look pretty awesome – How can I be sure they are female plants?
Tim Alchimia 2020-04-20
Hi Ronnie, thanks for your comment and question. I’m glad to hear your plants are growing healthy and strong, however, I strongly recommend that you carefully split them up into their own separate pots before they get too big, if that’s possible. They’ll do a lot better if they aren’t sharing the same root space and competing with each other for root space and nutrients. As for their sex, it could be that they haven’t expressed it yet, keep a look out for a teardrop-shaped flower bract growing from the4th, 5th or 6th node from the base of the plant, with a white pistillate hair protruding from the pointy end of it. That’s a female pre-flower. I hope that helps, best wishes and happy growing!
I don’t know how to distinguish between male and female plant.. and when it is the time to use?
Tim Alchimia 2020-04-14
Hi, thanks for your comment. Here on this page, you have a selection of photographs to help you distinguish between male and female flowers. They’re quite different and easy to tell apart if you take time to observe reasonably closely. However, if there’s something specific you’re unsure about I’ll be happy to help! Plants will show sex once they move from the seedling stage to the adult plant phase, this can vary depending on the genetics and the lighting schedule, but most plants will begin to show some pre-flowers at the 4th or 5th node around 6 weeks after germination. To break it down in the most simple terms, a male flower is a ball on a stick while a female flower is a teardrop shape with a white hair (pistil) protruding from the end. I hope that helps for now. Best wishes and happy growing!
Can someone please tell me if this is make or female. I mean at first glance it looks male but I don’t know. Should I keep it growing to find out or chop it right now. Thanks Ps.. I couldn’t post a pic .
Tim Alchimia 2020-04-03
Hi, thanks for your comment. You can send a photo to [email protected] and I’ll try and help. All the best!
Can i post a pic of my plant so you can tell me if its ok and if its time to harvest
Tim Alchimia 2020-02-24
Sure, send a pic to [email protected] and I’ll see if I can help out. Best wishes.
Toshio girl 2020-02-20
Hello, I planted a seed some one gave me just for the hell of it. I am using miracle grow and a plant light. The plant is about a foot tall now and can’t stand upright on its own. I have it propped up using a pencil. Is this a problem? I didn’t even expect the seed to germinate but it did. So I don’t know what I’m doing.
Tim Alchimia 2020-02-21
Hi, thanks for your question. Your plant is probably a bit weak just because it hasn’t been exposed to any wind or breeze, which would naturally strengthen the stems, so giving it some support as you have done is the best thing to do right now. You might have to use something a bit bigger than a pencil as it grows, but you’ve got the basic idea! Hopefully, this will be a good introduction to growing your own, enjoy it! Best wishes and happy growing!
Kristin Lopez 2019-08-17
I want to send pics and comment at same time so you can see what ur reading abt. I have a very short plant 1 outta 6 worked the rest were male. And or hermas but removed since I noticed and waited a week b4 I pulled then up and alot taller than my lil shorty thats already one big bid from the start never in all my yrs of growing have I seen a plant bud this short. Would love to send you pics I saw ur comment back to another guy that wanted to send pics bc we can’t uoload on here per say so I was wondering if u mind helping me understand this Thank u so much xoxo. Happy harvesting an hopefully smoking everyone and be safe and smart always. ✌❤?
Tim Alchimia 2019-08-19
Hi Kristin, thanks for your comment. Yes, it’d be very nice to be able to post pics here as well, who knows, maybe in the future? In the meantime, if there’s something you need to ask and you really need to send pictures, try [email protected] and I’ll see how I can help. All the best and happy growing!
Ray G. 2019-08-01
My 96 Peacemaker took over 2 weeks to indicate sex on 12/12. I don’t see any pollen sacks m, but where normally stigmas grow out, new growth/new shoots grew out instead. Now the stigmas are growing out of the new growth/shoots. Never experienced a plants taking nearly 2.5 weeks to sex. This plant has been unique since it was germinated. Is it likely it’s a germ?
Tim Alchimia 2019-08-02
Hi Ray, thanks for your question. Occasionally I’ll get a plant that takes ages to show sex, I don’t know if it’s indicative of any real problem or issue with the genetics though, just that some plants are slower than others. I’ve also seen the new growth start from where you’d expect to see the pre-flowers too, as you describe. It sounds like the plant may have a slight mutation in this respect, but again, I doubt it’s anything to worry about, certainly not a sign it will be a herm (although I can’t guarantee it won’t). Have you taken clones from this plant? If so then you could try some stress-testing on a clone and see if it reacts by popping out some pollen sacks. Otherwise, it’ll be a case of waiting and keeping a close eye on the plant throughout the rest of the flowering period. Often it’s the most unique plants that are the ones worth keeping, so don’t give up on this “freak” as it may well be a great plant! All the best and happy growing!
I have at least 8 sativa variety plants from female seeds growing outside in the ground. They are now 4-5 ft tall. Here in Sacramento we’re still getting 14 hrs. of sun daily. I was unable determine the sex of any of these plants not realizing that sex is determined 4-6 weeks in. These are way past that of course. This is only my second year growing and last year was no bueno. What can I do to determine the sex of these huge plants. I don’t want to cut them down till I know exactly what the deal is. I looked up online to see what female seeds looked like and planted only those. I hope that is the case. I do not see any seed pods at all. Thanks for anything you can assist me with.
Tim Alchimia 2019-07-22
Hi Chuck, thanks for your comment and question. I’ve heard of people claiming to be able to identify female seeds and distinguish them from male seeds, but I’ve also heard that this theory was roundly debunked and that there’s no way to tell the difference, but I’ve never tried it for myself so I can’t say with certainty either way. Your grow could be a useful experiment to see if there’s any truth in these claims. Unfortunately, at this stage, there’s really not much you can do apart from wait. Keep checking the branch nodes for any sign of flowers or pre-flowers. While it may be a little early for plants to begin flowering, at this time of year we can usually find a couple of these pre-flowers at the 5th node or above, although you may need a magnifying glass to see them properly. Another option, but it’s maybe too late for this season, would be to take clones from the outdoor plants and flower them indoors to check their sex. At this stage of the year though, your outdoor plants will have shown their sex before the clones have rooted, so this would ideally need to be done as soon as the plants are large enough to take clones from. I hope that’s helped somewhat, and do please let us know how you get on, I’m fascinated to find out how accurate the visual sexing of seeds can be. All the best and happy growing!
Hi, I’ve read through multiple conversations on this site and I’m in a bit of a pickle, as what I should do for the best in regards to my situation. If you have 4 plants and one of them has turned herme, I know it has as I’ve discovered to my horror an open Male flower with the little bananas, I have carefully cut down and removed it from the grow room, but am now very unsure if my other 3 have been pollinated, they are at the start of week 3 flower, I dont see any male sacks on the other 3 as yet but am considering cutting my losses as I dint want to waste more time, money and energy into pursuing a lost cause. what do you think I should do ?
Tim Alchimia 2019-06-25
Hi John, thanks for your comment and question. Sorry to hear about that hermie plant, but at least you found it relatively quickly. May I ask what the variety is? I wouldn’t trash everything yet though, often these male flowers turn out to be infertile and are unable to pollinate the female flowers. In your shoes, I would keep a keen eye out for more male flowers while paying close attention to the pistillate hairs/pistils of the female flowers, which when pollinated will turn brown and shrivel up. If you don’t see a whole load of brown pistils after a week or so then you’ll probably be fine. If, however, all the pistils have turned brown then yes, maybe it’s time to trash everything, but if it’s just a few then I’d carry on to the end of flowering. I hope that helps, all the best and happy flowering! To avoid any more male flowers appearing in the other 3 plants, I’d prune out any lower flowers that aren’t getting full light. This is a great trick for varieties that may be prone to intersex characteristics that reduces the chances of any male flowers appearing.
Meridee Thompson 2019-04-14
I have a question, I’m growing in 5 gal smart pots. Is it a good idea to pinch these back to increase yield or is it better to let them grow as they will?
Tim Alchimia 2019-04-15
Hi Meridee, thanks for the question. What kind of variety are you growing? If it’s an Indica-dominant or pure Indica strain then we don’t recommend pinching them out as they aren’t hugely vigorous and can often take a while to recover and begin to grow again. However, if it’s a hybrid or a sativa variety, then yes, it’s often a great idea to top them and let them form bushy and highly productive plants indeed! Just be sure to stop any pruning or pinching at least a couple of weeks before you plan to start flowering to allow them to recover and re-grow. Hope that’s helped a bit, all the best and happy growing!
hi i see my plant is a male what should i do keep growing it?how do i get it to seed
Tim Alchimia 2018-12-10
Hi Derek, thanks for your question. To make seeds you’ll have to use the pollen from the male flowers to pollinate a female cannabis plant. The best time to do it is around 3-4 weeks into flowering, depending on the variety this will allow 4-5 weeks for the seeds to mature fully. If it’s an early finishing variety then you’ll need to either pollinate earlier on in the flower period, or allow the plant to mature long past its normal maturity point. For seeds to be valid it’s important that they have enough time to fully ripen and become dark coloured with “Tiger stripes” rather than be a pale, greenish colour. I hope that clears up any confusion, feel free to ask any further questions on the subject. Happy pollinating!
hi tim, my girls are looking great. just notice my neighbors plants is a Male plant. can his plant pollinate my plants from 30 feet away?
Tim Alchimia 2018-09-10
Hi Jon, I’m glad the plants are doing well! Yes, a male plant can most definitely pollinate your girls from 30 ft away! Pollen can be carried for many miles on the wind, you’d better ask your neighbour to kindly chop that male down ASAP! All the best, fingers crossed for a sensimilla crop! Happy growing!
Hi ! I have been growing chronic plants outdoor.however I cant distinguish the sex. It seems like a tear form and pointy, however it looks like there is about 2/3 by node (particulary on top of branches) and still no visible pistils as it’s pre flowers. Definitely male or any chance to get a female ? It is possible that there is numerous female calix at the nodes (that havent showed their pistils yet) or it is normally coming alone or by pair maximum ? Thank you very much for your help!
Tim Alchimia 2018-08-31
Hi Jack, to be honest it sounds like they’re male flowers, just from the fact that they’re growing in clusters at the nodes. However, the teardrop shape sounds more like a female flower. Are they on little stalks, set away from the stem slightly? If so, then they’re definitely males. If in doubt, wait a little longer, you’re bound to see a pistil soon if it’s a female. Some plants can be really difficult to sex, be patient. Hope that helps, all the best and happy growing!
Tim nice call , plant are starting to bud, how do I make tricomb (sugar) what kind of nutrients?
Tim Alchimia 2018-08-27
Hi there Jon, the best way to understand the flowering process is to read our article here on the blog that deals with the subject in detail, explaining the changing nutritional needs of the plant. We aways stock a wide range of different fertilisers formulated specifically for flowering in our nutrient catalogue. All the best and happy growing.
jon andrews 2018-08-11
jon. my plants have been in pots since April, and still not show any signs (male/female) should I be worried?
Tim Alchimia 2018-08-14
Hi Jon, thanks for your question. If your plants are outdoors in the northern hemisphere then they’ll soon start too flower and you’ll be able to differentiate them around the end of August. Hope that reassures you, happy growing!
? have you heard of the term water pod , how does it happen.
Tim Alchimia 2018-08-10
Hi jr, no, I don’t know what you mean, please give more details, I’m intrigued.
Brandon Hazel 2018-04-08
I have yellow pollen on the leaves and some little white flowers all over but it sure does look like buds to me just with seeds.Is that possible and if so is it worth keeping?
Tim Alchimia 2018-04-10
Hi Brandon, thanks for your question. If you have pollen on the leaves then it sounds like you have some male flowers in there somewhere. When you say “little white flowers” are you referring to the white hairs of the female flower (pistils or more correctly stigma)? Or are you seeing little yellowy banana-like stamen of male flowers? You say the buds have got seeds in them? in that case it’s probably too late to worry about the male flowers, they’ve already done their damage! If your buds are seeded then you can smoke them, you’ll just need to be extra careful to remove all the seeds before you do, otherwise they’ll taste awful. Also remember that a seeded bud will not be as potent as sensimilla, as its energies will have been directed towards seed production instead of resin production. So you can either make some kind of resin extraction with the buds, or remove the seeds and smoke it, but next time you’ll need to be more vigilant and remove any male flowers earlier in the flowering process. If you’re repeatedly getting seeded buds then I’d recommend looking at your grow parameters, checking for light leaks and also growing seeds from a reputable breeder with a proven track record for stable genetics. All the best, happy smoking!
I just transplanted my plant not sure if it is female its two . weeks but .. I planted only 4 seeds .. Since I moved to plant to 65% nitrogen. The other 35% is compost .. .,I see 6 plants growing but some small . I,only,planted 4 .. Or 5 .. Ik it wasn’t 6,. . I believe the females love that combo if its females
Tim Alchimia 2018-03-29
Hi Brandon, thanks for your question. Firstly 65% Nitrogen sounds very strong, maybe I didn’t understand fully but you planted in a soil that’s 65% N and 35% compost? Small seedlings don’t need strong fertilisers, they’ll do really well in a lightly manured substrate, if the soil has too much fertiliser the plants will not grow properly and have many problems. Secondly, it’s not too unusual to see two plants emerging from one seed case. I’ve seen it a few times in my garden and frequently see people post photos online of this phenomenon, so it’s just possible that two of the four seeds you planted are twins, although it seems unlikely that two out of four seeds would show this characteristic. Is it possible that the other plants are something else? Are you using commercially bought compost or home-produced soil from the garden? If it has’t been sterilised it may well contain seeds of weeds and wild plants. All the best, happy growing!

we need to dip the marijuana before it goes into the dispensary. once it is dipped everything will be okay. no more labs. its not okay. stop extracting. just dip it so we can take a new step. once it is dipped the step will be available. pcp then ill let you know what angel dust is.
Ok i sent u some pics of the plant
Oh so just prune those branches out and i did get pics of them but i cant load them on here
Dani Alchimia 2017-08-10
Hi benny, Sorry for that, you can send the pics to [email protected] 😉
Not real sure its been raining last few days i do see bud flowers starting at the top but on a branch in the back of the plant has those sacks if possible i will try and upload a pic of what im trying to explain

Hi benny, Sometimes, plants only develop pollen sacks on the lower parts, or just in some branches. If that’s the case, simply remove any part of the plant with sacks and continue checking for new ones regularly. Best!
I got 3 plants in the ground i have an issue that it might be turning male its been growing since march would like some input on why its looking like some branches of it have seed looking sacks on it
Dani Alchimia 2017-08-07
Hi benny, It’s important to know if your plants are females (they have buds formed by white hairs), hermaphrodites (they have both buds and pollen sacks) or males (they only have pollen sacks). Only the first two cases can be seeded. If they are males (they also produce sacks and no hairs) you should remove them asap (also if they’re hermaphrodites). Do your plants have both types of flower (hairs and sacks)? What’s inside the sacks of your plants? Seed embryos or pollen grains? Best!

Hi i dont grow alot and only naturally in the garden i have a critical auto and is doing nicely has about 2 weeks left and has started to produce pods at the base of each flower what should i do if someone has some advice i would be grateful many thanks.
Dani Alchimia 2017-07-19
Hi Robert, If it is developing pollen sacks at the base of each and every flower, I’m affraid your plant will be completely seeded at the end of its life. You can try to remove the pods and check regularly if the plant produces some more, which you should also remove asap. But there’s not much you can do if your plant is hermaphrodite. Hope it helped!
What’s wrong if a female plant gets pollinated? Will the quality go down? What about THC/CBD content? Would the seeds be viable? Just wondering. I live in a rural area, and am wondering about wild weed or other neighbors plants.
Dani Alchimia 2017-07-10
Hi Koren55, Normally, when a female plant gets pollinated is produces less cannabinoids and terpenes, since it focuses on producing seed. So yes, the quality of sinsemilla is always higher than that of seeded plants. The seeds will be viable if you harvest them when they’re ripe, but: -If the pollen comes from a male, you’ll find females and males in the offspring of those seeds -If the pollen comes from hermie plants, you’ll find hermie plants in the offspring -if the pollen comes from reversed females, you’ll only find females in the offspring Hope it helped!

hello quick question. one of my branches broke I have tied it back up to support the break but I was wondering if it will turn the plant male cheers
Dani Alchimia 2017-02-24
Hi Chris, That would be really unlikely, that branch will either die or keep on growing, but I’ve never seen male flowers developing from broken branches. All the best!

Thanks dani you have given me hope, after reading yor sexing tips which I really wished I had I now think another is beginning to herm too, oh well, do you have any tips on what I should do with my cut down males. Is there any thing that isn’t a waste.
Dani Alchimia 2016-09-22
Hi Mark, You can try to juice the leaves or use them to make vermicompost. Apart from that, I’m afraid there aren’t much more options. Hope it helped!

I’ve got eight plants going one, unfortunately my biggest turned Hermie, it only showed pods for a couple of days before I noticed, I took it down immidiatly will this mess up the rest defiantly or is there any chance for some. This is an outdoor grow
Dani Alchimia 2016-09-13
Hi mark, From what you say, the rest of your plants should be OK, pollen sacks need some days to release pollen. Were the pods open? Unless you had lots of sack open, I wouldn’t worry about it, especially because you removed the pollen source (the hermie plant). If you have plants from the same strain that hermied, keep a close eye on them! Best!
I have a beautiful plant that is flowering and am almost positive it’s a female but today while I was looking my plant over I found what I thought was the beginning of a seed pod? My plant looks exactly like the one on this page where it says sexing your plants from cuttings . it is outside and this is my first rodeo so my question is. Is it possible that it’s both sexes and what should I do!? Also I have another one 5 foot away from is it possible to stop from being pollinated?
Dani Alchimia 2016-08-22
Hi Kevin, Hermaphrodite plants show both sexes in the same plant, and often pollinate other plants around them. You can find female plants that develop few male flowers during bloom, which is often no problem at all (we’d be speaking about 1-5% male flowers). But you can also find true hermies, which develop lots of male flowers and can easily pollinate other plants (furthermore, their offspring is likely to be hermie too). If your plant really develops both types of flowers, I’m afraid the only option is to chop it asap, otherwise you’ll end up with a fully seeded hermie plant, and your other plant will be also pollinated. Hope it helped!

I want to veg my outdoor longer but they are starting to show some flowers. Any recommendation on what I could I use to stimulate rapid growth to make them hold off on blooming?
Dani Alchimia 2016-07-22
Hi Left Coast, You should use some light source at nights to “break” the dark period of the plants. If you light your plants after 3-4 hours of darkness for around 30 minutes you’re breaking the bloom photoperiod, so your plants should keep on growing until you remove that light source. Some growers use different schedules, like turning on the lights every 45 minutes for 15 minutes during the night. Hope it helped!

It was is the middle of july in Sacramento Ca. Should i change my feeding my plants for flowering now till Oct. And will they grow. Bigger? They are in 27 gallon pots with about 3 to 4 ft tall.
Dani Alchimia 2016-07-14
Hi Ginger, You should start using nutrients for Bloom as soon as you see the first tiny buds developing. Depending on the strain, it’ll stretch more or less before starting to bloom (Sativas normally stretch much more than Indicas). Hope it helped!
Can I grow about 4 plants in one pot and when flowering if I come across any male plant can I just remove a male. And is 2 125wats CFL ok for 4 plants
Dani Alchimia 2016-07-04
Hi agi, The roots of the plants need as much space as possible to grow, that’s why we normally use one pot per plant. You can do as you say without problem, but try to use a large pot so that once you remove the males your females have enough space to grow. About CFL’s: 2x125W is ok, but do not expect the same results than when using an HPS lighting system. With two CFL you’ll have enough light to cover a 1m2 area, but as I said you won’t have the same results as if you were using, for example, a 600w HPS. Hope it helped!

When it comes to harvesting home-grown marijuana, female plants are the name of the game. Not only do female plants produce the coveted buds needed for medicinal purposes, but they also have higher potency and THC content compared to their male counterparts. You’re in good hands—we’ve outlined everything you need to know about identifying female and male marijuana plants, so you can easily make the most out of your crop at home.
Look for thicker, sturdier stalks with fewer leaves on male plants. A male plant, compared to a female plant of the same strain, generally has a thicker stalk. That is because it gets taller than female plants and needs to be able to support the weight. They also have fewer leaves than female plants.  X Research source
- You need to check every plant to determine if it is male or female, as one rogue male can wreck your harvest.
- In general, male plants show their sex 7-10 days (indoor) or 3 weeks (outdoor) before female plants.
- If you’re trying to create new plants or reproduce, you need to leave these balls undisturbed.
- Female plants will have these bulbs too, but will also have long, translucent hairs on them. If you only see 1-2 on a plant, wait and see if more develop before cutting them.
- “Hermies” are generally undesirable plants, and they can ruin a small crop with their pollen if you’re not careful.
Throw out or remove male plants unless you specifically want seeds. Once you’ve determined a plant is male, you need to get rid of it or it will ruin your crop. Do not try and remove the buds by hand, as missing even a few will significantly decrease your crop. While most growers simply throw the plants out, a few keep them around for breeding purposes. If you do, put them in a separate room from the females, and make sure you don’t track pollen in from the male room to the female room on your clothes or hands.

- You can purchase “feminized” seeds as well, which usually create close to 100% female plants. However, there are occasional errors, and you should still keep a close eye on your plants to make sure there are no rogue males.  X Research source www.theweedblog.com/sexing-your-outdoor-marijuana-plants/
Note fuller bodies of leaves, when compared to males, on a grown female plant. If you’re trying to sex mature plants, one of the easiest indicators is how bushy they get. Male plants have thicker, sturdier stalks and very few leaves. A female of the same strain will be shorter and bushier, with more leaves, especially near the top.
- Male plants will have the small buds (pollen sacs) but will not have the associated hair growing out of it.
- Plants can grow both pollen sacs and pistils. If it does, it is hermaphroditic and should be treated like a male.
Separate your females from any males, as only females create buds. Only female plants will produce enough THC to be used as medicine, but they won’t create much if they become fertilized. The pistil is meant to attract pollen. If it gets it, it will create a seed, and all the plants energy and nutrients will be spent making seeds, not making big, THC-full buds. Your female plants are the only ones that will produce a crop, but only if they stay away from the males.
In general it’s not a good idea, because you can bring bugs and other things into your house, but as long as it’s not being kept around indoor plants, it should work. Just make sure to keep an eye on the plant and give it plenty of fresh air, as that is likely what it is used to. Keep in mind that the sun is the best grow light, though, so you should leave it outdoors if you can!
It needs a light cycle with a minimum of 12 hours of uninterrupted, complete darkness every day to trigger and maintain flowering.
Check frequently once your plants have hit the 6-week mark — you want to know you plant’s sex as soon as you can.

If you’re growing marijuana plants, it’s important to be able to tell male and female plants apart, since only the females produce the buds that contain high concentrations of THC. To identify male and female marijuana plants, make sure they’ve been growing for at least 6 weeks, since both types of plant look the same in their early stages. Then, look for male plants to have thicker stalks and fewer leaves than their female counterparts. You can also tell if a plant is male by checking for little flowers or bulbs at the joints of the stalk and branches. By contrast, you’ll see small, translucent hairs on the same areas of a female plant. Once you’ve identified that a plant is male, remove it from your growing area to prevent it from pollinating the female plants, which will result in your THC harvest being reduced. For tips on what to do with plants that have both male and female organs, read on!
