If you are growing marijuana for medicinal purposes, you need to know how to identify female and male marijuana plants. Almost all growers prefer female marijuana plants because only females produce the coveted buds needed for medicinal purposes. Male plants have low potency and THC content compared to the female plants, and they are kept to mostly produce seeds.
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!
The traditional way to germinate a seed is to bury it one-quarter inch deep in moist soil and watch it closely for a sprout. A freshly germinated seed has a very fragile root that is easily damaged when the seed is transplanted. This method allows the seed to germinate without root interference.
After the time has passed, seeds that float can be considered poor quality and discarded. Seeds that have sunk to the bottom of the glass are healthy, high-quality seeds. Once the test is complete, the seeds need to be germinated right away. Their shells will be soft from soaking in the water and will not survive storage.
The float test is a more scientific approach to determining the quality of a seed. The test involves filling a drinking glass with spring or distilled water and placing the seeds inside of it. Allow the seeds to soak for one to two hours before determining quality.
How to Germinate a Marijuana Seed
Ask any experienced grower how to produce a hardy marijuana plant and they will say to start with a seed for a good strain. Lighting, soil, nutrients, and water play large roles in the final yield, but starting with a high-quality seed gives growers the best genetics with the highest potential yield possible. Most people find their first seed mixed in with marijuana, but most of these seeds are low quality and may grow to be male plants. The best way to get high-quality seeds is to purchase them from a reputable marijuana seed retailer.
Good quality marijuana seeds have a waxy coating around the shell. This is easy to see if the seed is held up to the light because the shell will have a slight sheen.
A high-quality marijuana seed has a dark color, typically a shade of brown, grey, or black. It should have tiger-like stripes or spots on the entire surface of the seed. If the seed is green or white, it is immature and is not likely to germinate. In the rare circumstance that an immature seed germinates, it takes much longer than it would for a mature seed.
There are several visual indicators that can give a person an idea about the quality of a marijuana seed. Some details are easy to spot while others take a higher level of scrutiny.
If the sprout comes out of either the TOP or BOTTOM of the seed, it is a FEMALE.
If the sprout comes out of either SIDE of the seed, it is a MALE.
I recently tried this out and I can confirm that it works. I germinated 5 seeds. 2 of them that I planted where sprouted out of the side (male) and the other 3 sprouted out of the top/bottom (female). Out of the 2 seeds that were potentially Male plants, 1 of them has shown sex and it is indeed a male. The other plant hasn’t shown sex yet but is very thin and doesn’t have many leaves, making me believe that it is indeed another Male.
Firstly, I’m pretty new to posting on this forum so hopefully I posted this in the right category.
I always see this question everywhere, "Can you tell if a seed is male or female?"
I may have the answer but would like for other growers to please try this out and confirm if it works for them.
To tell if a seed is male or female, you must first germinate it.
Once the seed sprouts, you need to look where it sprouted from.
