HOW TO GERMINATE MARIJUANA SEEDS

How can I germinate cannabis seeds? It is a Frequently Asked Question among most wannabe cannabis growers. Well, whenever you see a cannabis strain flourishing in a fellow connoisseurs grass farm, one thing is sure – the process of getting the favorite weed starts with germinating cannabis seeds. As of this moment, you may be asking, “where do weed seeds come from?” Ganja seeds are not something you will go to your nearest agro-vet and make your purchase. Thankfully, you are on the very website that deals in an array of cannabis seeds, as you will see on Leafly.

Also, before germinating weed seeds, you ought to ensure that your country legalizes the cultivation of pot; otherwise, you will find yourself on the wrong side of the law. We can’t insist enough that you have to order your weed seeds from a reputable seed bank as they will ensure that these goodies are supremely packaged, and with the highest chances of germination. Mature and ready-for germination seeds are mostly dark brown, and with a firm feel. That said, is the seeds are extremely wet or dry, they won’t germinate and so throwing them away is inevitable.

After getting your preferred seeds from the Amsterdam Marijuana Seeds Company, you need to ensure that the growing space is appropriately prepared to necessitate the growing of healthy ganja seedlings. Otherwise, it would be the worst idea to pop weed seeds when the growing area isn’t sufficient to enhance proper spacing of the plants.

Germinating Cannabis Seeds: Requirements

  • Water
  • Air
  • Heat.

Let’s now debunk each requirement to the entirety.

Water best gets for breaking seed dormancy. However, one ought to be careful not to under-soak or oversoak their seeds. Ideally, a day is enough to soak your grass seeds. That said, even the hardest seeds will have received sufficient water.

Provided you subject your seeds to the sufficient amounts of water, the taproot should appear through the shell. This is the critical time to ensure that the taproot also called the cannabis white tendril, gets water; otherwise, it will dry up should it lack water.

The rate of respiration in a dormant seed is meagre. This means that oxygen gets used at trace rates if all any. However, cannabis seeds require sufficient oxygen to pop. So, where does this oxygen come from when a weed seed is germinating? Well, this is the best point to understand why water is such crucial in germination.

In addition to breaking seed dormancy and keep the taproot alive, water also contains air, which is in this case oxygen. The presence of oxygen, therefore, enhances the ultimate germination of cannabis.

This is the most overwhelming part of cannabis cultivation. Picture this: cannabis seeds don’t require excessive heat or coldness. That said, you would need to play with humidity levels in such a way that the germination medium has a lukewarm temperature. Even though cannabis seeds can grow in colder areas, it may take longer, not unless you filter through the Amsterdam Marijuana Seeds and select the strain that gets described as doing well in cold regions.

We mostly advise growers that if wherever they are is extremely cold, they may need to buy incandescent bulbs and erect them above where the seeds are germinating.

While those are the basic requirements, other factors can best get considered depending on the chosen method of germination. We are going to illustrate the different ways of germinating cannabis seeds using the easiest to the most challenging practices of germination.

Cannabis Germinating Techniques

1. The paper towel method

The paper towel method of germinating weed seeds is arguably the easiest. The factors to consider when using the technique include:

  • Two plates
  • Paper
  • Neutral water
  • A mixture 40% sand and 60% soil
  • Pots for the plants
  • A fluorescent tube.

1. Place the seed between some dampened pieces of paper towel. It’s highly recommended to use distilled water to germinate your marijuana seeds.

2. Afterwards, place the marijuana seeds (in the towels) between 2 plates and put it somewhere warm. The best temperature to germinate your cannabis seeds is between 21 and 25 degrees celcius.

3. Open the plate’s only once a day just to have a look. Take note of a tiny white root tip starting to emerge from the marijuana seed. Some cannabis seeds will sprout in a day, while others need a week before they crack open.

4. Ensure that the towel will not dry out. Put a little bit of water over it every three days.

5. Once the root has come out of the marijuana seed, you have to put the cannabis seeds in a small pot filled with soil.

6. Make a little hole in the soil. Holes with half an inch deep are suffice. Plant the marijuana seed with its root facing the hole. Cover the hole with some soil and give it a little bit of water. Make sure the marijuana seeds are still covered with soil after you water them.

7. Place the pots with the marijuana seeds under a fluorescent lamp and give it a little bit of water every day.

8. Turn the lights on for about a few hours a day. After 3 to 7 day’s, you will see the first few signs of the marijuana plant. The lamp should be at least an inch above the topmost portion of the young cannabis plant in order to avoid burning its leaves.

9. After 3 to 4 weeks, the marijuana plant should be about 4 inches high and thus big enough to be transferred to a bigger pot. If the temperature allows it, you can now put them outside or place them in your indoor growing room.

2. Direct germination

The direct germination of ganja seeds is as easy as it sounds. Necessarily, the marijuana seeds will pop after getting subjected to water, where the white tendril will go downwards and start growing.

The best thing we like about the direct germination of the pot is that there is no reason to worry about the hassle you meet when the time for transplanting comes. Substantially, this method listed on our how to germinate cannabis seeds guide works across every other growing medium, but the difficulty may vary.

If you do everything right, the seeds will come out sturdily since they will not undergo any stress and will adapt to the very conditions of growth.

So, if you decide to germinate cannabis seeds directly on soil or soilless mediums, the process is all the same – make a hole between 1.5 and 2.6cm in moist soil/soilless medium, but where it gets grown, the medium shouldn’t be soaked.

1. Overnight soaking

This process typically involves the usage of a clear glass cup and soaking the weed seeds in warm water, overnight. The process is ideal for those cannabis seeds that have somewhat hard shells or those that are aged.

If the seeds are excellent, they start off by floating in the slightly warm water but sink with time. The reason for using a clear glass cup is to ensure that you may keep in pace with how the seeds germinate. Should you see a white tendril, then rest assured that your marijuana seeds have germinated!

However, the main emphasis is that the water should be slightly warm as when it’s hot, it will end up destroying the seed and inhibiting its chances of germination. The time it takes for a viable seed to sprout is dependent on the age. For instance, newer marijuana seeds germinate in a few hours after getting soaked, with old seeds taking their ample time for the taproot to penetrate through the shell. Either way, it would be worthwhile not to saturate a seed for more than 30 hours.

2. Using a germination station

A germination station best fits amateurs, even though aggressive beginners can use the technique for germinating cannabis seeds. So, what is this station? It is a tool tailored explicitly for providing a grower with the optimal conditions for germination, regardless of what is getting sprouted.

A germination station is affordable, and the grower doesn’t have to break the bank to have their tool. However, if you are genuinely on a tight budget and are convinced that going the DIY way is possible from your side, then it could be a breeze to make one.

You need to follow these simple steps:

Have a plastic dome ready

· Place the same plastic dome on a heating pad

· You have your germination station now.

A professionally manufactured germination station is ideal for amateurs since it provides all the necessities for germination and works efficiently and, of course, well.

If you buy one, using it is as easy as we are going to debunk here. Firstly, it has a seedling cube for germinating the seeds. Secondly, should you need to transplant the seedlings, you typically need to carry the cube with the seedling and plant it on where the growing medium where you have made the hole.

The roots appear from the bottommost part of the cube, so, you need to place the cube as it is on the growing medium while factoring that that medium shouldn’t be oversoaked.

3. Seedling plugs

If you are an expert, this is your thing when it comes to germinating marijuana seeds – seedling plugs and starter cubes. These plugs are already readymade and with instructions to make pot germination a breeze.

Using it involves placing the marijuana seed of your choice in the plug or cube, follow the watering instructions, and the seedlings will sprout as soon as possible since they’ll be having the factors necessitating their ultimate growth.

So, how do these tools work? Well, a plug or a cube has a hole, where the cannabis grower will place their seed. That said, one needs to put that very seed on the designated hole and place their finger on the topmost part to make the seed enter the plug or cube well.

Provided the seed is viable; this is one of the few methods that all marijuana growing experts claim to guarantee 100% sprouting chances.

Transplanting your germinated cannabis seedlings

You now have the 5 top-tier procedures for necessitating the cannabis seeds germination. Now that the highest chances are that all the weed seeds will germinate, how do you go about planting and taking care of the seedlings?

The first step to follow is ensuring that you have a ready growing medium. This could be an outdoor, indoor, or hydroponics mediums. Let’s take an example that you would like to grow cannabis in pots. The critical idea is ensuring that you fill the growing pot with sufficient soil while ensuring it is loose to make the seedling flourish stress-free.

Use a pencil to bear a hole up to ¼ inches deep and transfer the seedling into the very hole using a pair of tweezers. Using your bare hands may lead to the distortion of the taproot/ white tendril. Also, ensure that this taproot is what faces downwards, and cover the seedling-to-be in a thin soil layer.

Ensure that the seedling gets ample moisture, and if need be, use a pH meter for accuracy purposes. You don’t need to pour loads of water on the seedling as it will perhaps die. Instead, use a sprayer bottle to water your cannabis seedling.

The seedlings should be above the ground within a week, and the chances are that if it doesn’t within 9 days, your seed may have gotten spoilt. Also, heat is primal and grow lights may be used to up the chances of your seedling sprouting. Happy cannabis cultivation!

How to Germinate Seeds via Paper Towel Method

Cannabis seeds are natural things and you can’t expect 100% germination every time. Unfortunately, that’s just not how nature works. Many factors can affect germination including genetics (some strains germinate easier than others), the age of seeds, and how well they were stored. But I’ve been lucky and gotten 100% germination ever since I started using this method.

Paper Towel Method – Germinate seeds between wet paper towels, lock in the moisture with two plates, and place on a seedling heat mat for a few days

Pros

  • High Germination Rate – Almost every seed with germinate if you follow the instructions
  • Fast – Often takes only 1-3 days to see roots
  • Keep Track – You can check on seeds without disturbing them
  • Less Space – Use less space than planting seeds in pots (helpful if germinating lots of seeds at once)
  • Fun – I personally love seeing the whole germination process and it makes me genuinely feel closer to the seedlings
  • Multiple Steps – Not as simple as planting seeds directly in soil!
  • Requires Supplies – You need cheap paper towels, seedling plugs, and a seedling heat mat
  • “Bucket Head” Seedlings – I’ve found that shells are more likely to get stuck on the seedling leaves with this germination method because seedlings aren’t pushing themselves out of the soil. You may want to use tweezers to remove the shell gently, or just leave them be. However, this can happen with any method (instructions at the end of the article explain how to remove stubborn shells safely) and I personally find the increased germination rate makes this worth it.

Seeds typically germinate in 1-3 days!

Create happy little seedlings in less than a week!

How to Germinate via the Paper Towel Method

Supplies

  • Cheap paper towels – Why cheap paper towels? Seed roots grow into expensive cloth-like ones and have to be cut out (learned that one from experience)
  • Two Plates – You need to lock the moisture in during the germination process
  • Cannabis Seeds – If you need seeds, here’s a list of seed vendors that ship worldwide
  • Rapid Rooters with Tray – The perfect environment for newly germinated seeds
  • Seedling Heating Mat – Or any warm surface that stays about 70-85°F (20-30°C) to keep seeds warm

Cheap paper towels (don’t use the expensive cloth-like ones!)

Rapid Rooters (note: extra Rapid Rooters can be stored in a cool place for future grows)

Seedling Tray to hold Rapid Rooters

Seedling heat mat to keep seedlings warm (or any surface that’s about 70-85°F or 20-30°C)

1.) Put 3-4 Layers of Paper Towels on Plate

You don’t want to load your plate up with tons of paper towels, but it’s nice to have several sheets so they can hold plenty of water. If necessary, fold or cut the paper towels to size so everything fits completely inside the plate. If a paper towel is sticking outside the plates, everything will dry out quickly.

You may need to cut (or fold) paper towels so they fit completely inside plate

2.) Label the Strains

If growing more than one strain at a time, label the paper towels so you’ll know which seed is which.

3.) Add Water & Seeds

Add some water on top of the paper towels so they’re soaked through, then place seeds down. I add water first to avoid accidentally moving seeds. It’s also a good idea to keep the plate flat so seeds don’t roll around.

4.) Cover with 1 Sheet of Paper Towel

Put a single sheet of paper towel on top. With just one sheet you will be able to see whether the seeds have germinated without having to disturb them. You may need to add a little extra water so that the top sheet is moist all the way through.

With a single sheet on top, you can still mostly see the seeds

5.) Put 2nd Plate on Top

Lock in all the moisture by putting another plate on top.

6.) Place on Seedling Heat Mat

Plug in your seedling heat mat. It should warm up quickly. I’ve put the plates directly on the mat before, which worked well, but sometimes I worry my little weed seedlings may get too hot with the plate directly on the mat. Since I already have a Rapid Rooter tray for later, I place it between the mat and the plate. Feel free to use something else like a book or towel. The basic idea is to put some space between the heating mat and the plate so the plate still gets warm but the extra air space keeps the heat nice and even.

Why a seedling heat mat? Seeds germinate significantly faster when they’re kept 70-85°F (20-30°C). A seedling heat mat keeps seeds warm during the germination process. However, any warm spot works just as well (for example, on top of the refrigerator is the perfect temperature for some people). When you touch the wet paper towels, they should feel warm but not burning hot.

7.) Check on Seeds at Least Once a Day

Ensure paper towels don’t dry out. You may have to add more water occasionally to keep them wet. You can usually tell when the seeds have germinated without looking under the top sheet. This means you can check on your seeds regularly without disturbing them by picking up the top plate.

Seeds typically sprout in 1-3 days. Certain strains and older seeds may take a few extra days.

8.) Put Germinated Seeds in Rapid Rooters

Once seeds have germinated, gently pull off the top paper towel to reveal the seedlings underneath.

Carefully and slowly remove top paper towel sheet

Did you know the first two round seedling leaves were already fully formed inside the shell? The germination process only releases them. New leaves are yellow at first but turn green once they start getting light.

At this point, you may see some seedling leaves have already broken free of their shells. That’s awesome. These seedlings often grow the fastest.

If there’s a short root or seedling hasn’t germinated yet, put the paper towel back and gave the seedling one more day. Seedlings grow faster if they have a bit more root before being planted.

This Critical Purple Kush seed took an extra day to germinate compared to the other seeds. I gave it one more day after this so the root could get longer before I put in a Rapid Rooter.

I recommend cutting your Rapid Rooters in half to make it easier to place germinated seeds. Even a seed with a long wiggly root will usually easily fit into the “crack” of the Rapid Rooter. This prevents you from bending the roots.

Cut Rapid Rooters in half to make it easier to insert germinated seeds

Try to place the seed head close to the top so they don’t have far to go. I’ve found that some seedlings don’t make it to the top if you put them too far down.

If the seedling has already lost the shell, place the leaves close to the top. These seedlings often grow the fastest.

Otherwise, add the seedling, root down, with the shell close to the surface

Gently close around the seedling

Put into the Rapid Rooter tray (make sure they’re moist all the way through!) The bottom shell of the tray will hold extra water so plugs don’t dry out.

Add enough water that all the Rapid Rooters appear dark, but not shiny from too much water. Once you’re done, put the trays back on the seedling mat. Young seedlings love warmth!

9.) You Have Seedlings!

The leaves should appear above the Rapid Rooters within a day or two.

Just 12 hours later, several seedlings have already appeared above ground.

At this point, the seedlings are ready to be put under a gentle light. A sunny window works well, though your regular vegetative grow light should be fine as long as you keep it twice the normal distance away. Avoid touching the seedlings if possible. This is when they’re most vulnerable.

Within a day or two under a light (or in a sunny window), you’ll have a bunch of happy seedings!

The seedlings are ready to go in plant containers once they’ve spread out their first set of serrated leaves (to about the width of the Rapid Rooter)

At this point, you can plant the whole Rapid Rooter. Don’t forget to label the strains!

Move the grow light down to the standard distance once the plants have 3 sets of leaves. By now they should be growing fast!

Note: Move grow light down early if seedlings start getting tall with long stems. Tall, stretchy seedlings are telling you they want more light.

What If the Seedling Shell Gets Stuck? (“Bucket Head” Seedlings)

One downside to this method is sometimes a seed shell will get stuck on the seedling. Here’s how to deal with that.

Helpful Tool: Pointy tweezers (though most tweezers will work in a pinch)

Sometimes leaves get stuck in the shell. Here’s what to do.

First, give the seedling 24-48 hours to see if it pushes the shell off on its own. Many seedlings just need a little extra time and don’t need your help.

Ignore stuck shells if the leaves are already free. The shell will fall off on its own.

If you don’t see any progress and leaves still seem trapped after a day or two, you may need to remove the shell to release the leaves contained inside. If leaves can’t break free and see the light, the seedling may die.

Close tweezers so they are as narrow as possible and put inside the crack. Then slowly allow tweezers to open, which will gently pry the shell apart.

I used to use my fingers to remove shells but it can be hard not to disturb the seedling. Then I learned that a pair of pointy tweezers can be inserted into the crack and allowed to gently open to pry the seed apart. Don’t tug or use any force whatsoever. Just gently and slowly release the leaves. The leaves may be stuck to the shell at first and it can take several seconds of gentle tugging for the leaves to slowly loosen and pull away from the shell. If you’re having trouble, add some water to the stuck part and wait a few minutes to help soften it up.

If the seedling leaves aren’t opening up because they’re stuck inside the seed membrane, wet the membrane and give it a few minutes soften up. Then use tweezers to gently remove the membrane. In some cases, it’s easier to stick the tweezers inside and pry the leaves apart just like with a shell.

If leaves are stuck inside the shell membrane for more than a day or two, do this: Wet the membrane, wait a few minutes, then use tweezers to gently pry it away from leaves.

Once you can see the two individual leaves are separated, you’re good to go!

No germination method is perfect (some seeds just won't germinate), but I've gotten 100% germination ever since I started using this method.
