How to Tell If A Cannabis Plant Is Male or Female

When it comes to growing cannabis, it truly is essential that you learn the difference between male and female cannabis plants. By learning this simple technique, you can easily decide what you want to pollinate and what you don’t.

Understanding Plant Reproductive Morphology

First, let’s take one step back to fully grasp why we need to separate cannabis plants by male and female in the first place. This is commonly referred to as the plant reproductive morphology, which is simply the study of the physical form and structure of a plant’s sexual reproduction parts.

While there are actually many complex forms of morphology, for the sake of keeping it simple, we’re only going to cover three of the most common ones.

Hermaphrodite (bisexual):

This is a type of plant that forms both male and female parts on the same plant. Therefore, this plant will be able to reproduce on its own. However, in cannabis plants, you can discover a “hermied” plant by banana looking shoots, which form on the flowers. While this can be the genetics of the cannabis strain, it may also be an indication of the plant getting too stressed out. When a plant gets too stressed and fears it will die, it may begin to form male reproductive parts. This is to ensure that seeds can drop for its survival (keep reading for more info on detecting “hermied” cannabis plants).

Monoecious:

For this type of plant, it will form both male and female reproductive parts. However, they will not be on the same flower as they are with hermaphrodite plants. Within monoecious plants, you will find one flower has female parts, while another has male parts. In cannabis, this is very uncommon to find. Actually, it’s only been reported a few times in history and something that we’ve never personally seen. If this were to happen, you would find one stalk with definitive male characteristics and other branches of the same plant with definitive female characteristics.

Dioecious:

Now, with a dioecious plant, you will find that the plant either produces all male parts or all female parts. This means that no single plant can reproduce on its own. The female actually needs its male counterpart to continue producing seed for the following year. And, you guessed it, this is the category cannabis falls into and why you must separate your males from females. If you fail to separate them all, you will likely find that the male plants pollinated your females. Therefore, leaving you with a handful of buds chalked full of seeds.

How to Tell the Difference Between Male and Female Cannabis Plants

Now, with an understanding of the various sexual organs within cannabis plants, let’s get to the fun part – separating your lady friends from their male counterparts.

After the seeds have sprouted and the plants have had a chance to grow, it will be time to find out which ones you’ll be keeping to flower out and which ones you will be chopping down to avoid seeded buds.

Usually, when starting from seed, you will need to wait about four to six weeks before the male and female parts will be formed well enough for you to see the difference.

How to Tell Female from Male Weed Seeds?

Determining the sex of your cannabis plant is very important. Most growers require female plants because these are the ones that produce the resiny buds we love. Males, by comparison, simply produce the sacs of pollen used to pollinate female strains to produce seeds. Female varieties shouldn’t be pollinated. Otherwise, they will no longer produce their THC-laced resiny buds.

In a regular growing setup, males have to be removed as soon as they’ve spotted to reduce this risk of pollination. Otherwise, you run the gamble of turning your precious resiny buds into seeds and spoiling the whole crop. But can you tell the difference between weed seeds before they’re cultivated?

Can you tell male from female cannabis seeds?

Simply put, there is absolutely no way to tell the difference between male and female cannabis seeds before they’re planted. There is nothing in their appearance or size to indicate what will grow. The only way to tell is to grow it, wait and see.

You can, however, pick up feminized seeds directly from Weedseedsexpress to guarantee a female plant every time. Feminized seeds are bred exclusively to produce female plants. Knowing your seeds are female from the beginning is the perfect solution for hobbyists and smaller setups that can’t waste resources.

If you’d prefer to plant regular weed seeds, experiment and discover the sex of your plant as it grows, you can choose these here too.

Myths about determining the sex from the cannabis seeds’ appearance

There are plenty of myths out there on how to determine if a cannabis seed is male or female. Don’t be duped by them.

One of the most common is that female seeds have perfectly round crater-like impressions under them, just like a volcano. This is false. Crater-like impressions or indents can form on any and all seed varieties, no matter the sex.

Other myths include those pertaining to size and shape. Neither male nor female seeds are smaller or bigger than one another.

What’s more, some have speculated that male seeds are heavier, ragged or protruded, meaning that if you roll them on a table, they thump like a flat tyre. By comparison, it’s supposed that female seeds are smoother and therefore roll easily across a table. This is also false. Any seed can be any shape – it’s got nothing to do with sex.

Finally, there are no other indicators to tell the sex of cannabis seeds. No aroma, weight difference or coloration. If you find a chart indicating such methods of detection online, ignore it. This will prevent you from wasting time cultivating and accidentally pollinating your crops.

What can you do to tell male from female cannabis seeds?

The only way to sex your cannabis seeds is to sow, grow and check. Most female strains begin to show characteristics of their sex after 4 weeks or more, just before the first stage of flowering.

You have to wait out the vegetative stage until the hair-like pistils begin to grow from the stems. This is indicative of the pre-flowering stage and a sure-fire sign of a female plant.

By contrast, male plants show their signs much earlier. Male plants grow sacs within the crevices of stems which are filled with pollen. As soon as you notice these, it’s time to remove them from your crop to prevent pollination. Males typically grow these sacs in as little as 2 weeks, giving you plenty of time to react.

If you’re worried about your crops pollinating without you knowing, there are a few tricks you can use to identify sex early.

Instead of waiting it out and meticulously inspecting your plant, consider placing an opaque black or paper bag over a growing tip on your plant during vegetation. Keep the bag on for 12 hours in a 24-hour period and repeat. This manipulates the light cycle and forces the plant to pre-flower early. You can then check the sex of your plant after roughly 7 days before allowing it to revert.

There are also professional, scientific ways to determine the sex in advanced botanical setups, but aside from mailing off samples to labs, few can try this at home.

Alternatively, feminized seeds provide a more fool-proof strategy for cultivating healthy, resin-producing crops. You’ll have no need to sex your plants early and run no risk of accidentally pollinating your crop.
