The alternative to this is to risk buying seeds from a hobbyist. This isn’t to say that hobby growers cannot produce fantastic genetics, but if you don’t know them or their skills, there’s no way to know whether your seeds will grow.
The one true method to test the genetic potential of a seed is to simply put it in the soil. It won’t take too long to see the results. This option is best for the hobby home grower who has time and space to spare for a risky project. Growers cultivating cannabis for commercial use likely don’t have the excess time to invest.
A quick web search will bring up all kinds of myths about how to tell female cannabis seeds from males. One of the most popular ones comes from a chart showing 5 different seeds that claims that the female seeds have “a perfectly round volcano-like depression at the bottom (from where the seed was attached to the plant).”

Quality seeds are the key to healthy plants and good harvests. While proper feeding/watering and good light quality obviously also affect the health and yield potential of your plants, starting a grow with top-shelf genetics is equally, if not more important. But how exactly do you tell quality cannabis seeds apart from the rest? In this article, we’ll show you exactly how to spot top-quality cannabis seeds, avoid duds, and start your grow off right.
Remember, just like animals and other living things, cannabis seeds are biologically different from one another (even if they are technically the same strain) and therefore will exhibit different physical characteristics. Don’t let these natural differences fool you into thinking that a larger, rounder, and darker seed (for example) is of better quality than a lighter, smaller, and more oval-shaped one.
We hear this question all the time from clients and beginner growers, and the answer is a resounding no. There is simply no way to tell the sex of a cannabis seed just by looking at it.
With this said, you may get lucky if the strain they were growing really is prime. In this case, it’s worth carrying out the following test to see if it’s worth germinating.

Mycorrhizal fungi participate in a give-and-take relationship with cannabis plants. These species form networks of thin, hair-like filaments in the soil—known as mycelium—and produce enzymes to break down organic matter.
Although not genetically part of the cannabis plant, mycorrhizae form a mutually beneficial relationship with cannabis roots that helps both species survive and thrive. These fungi appear all throughout nature and form a fascinating symbiotic relationship with up to 90% of plant species.
Without a doubt, cannabis claims the title as one of the most beautiful plants on Earth—from its glittering trichomes and signature leaves to its complex root system. Many growers frequent their grow rooms just to stand in awe at what grows before them.
Mycorrhizae ultimately act as an extension of the root system. Not only do they break down organic matter to release nutrients, but they also transport these important molecules from areas plants could otherwise not reach. Ultimately, mycorrhizal fungi play a fundamental role in plant nutrition and soil biology and chemistry.
