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.

Mature cannabis seeds usually have a hard outer shell that can vary in color from very dark (or almost black) to very light grey and may have tiger-like stripes. You should be able to firmly press these seeds between your fingers without damaging them.

Growing Seeds From A Bag (Bagseed)

Unlike other agricultural crops (like vegetables, fruit, or grain), cannabis hasn’t undergone the vigorous breeding techniques that ensure a stable crop. This means that you’ll sometimes sow a pack of seeds technically labeled as the same “strain,” but may end up with very different looking plants. It also means that the individual seeds you buy from a seed bank can vary in appearance.

Some smokers might be pleased to see some cannabis seeds in their bag, and might think themselves lucky. However, finding seeds in a bag is bad for various reasons. For one, this means the grower has messed up and allowed their female plants to be pollinated by an invading male. When flowers are pollinated, they stop producing THC-containing resin and divert their energy toward producing seeds. Secondly, the seeds will have added to the overall weight of the bag, which means less weed for your buck.

Immature cannabis seeds, on the other hand, tend to be green and have a soft outer shell that breaks when any kind of pressure is applied to it.

Properly floating cannabis seeds is as easy as placing these seeds in warm filtered water with a

In general, growing cannabis from seed can offer the opportunity for growers to possibly create something new which can be exciting and different. Besides genetics, phenotypes based on the grow environment can create different alterations of the same cannabis strain (Conviron, 2017). An individual can easily purchase seeds online or by pollinating and hybridizing one’s own seeds for use. Cannabis growers may find more success by first floating or soaking their cannabis seeds in filtered water, than planting directly into a growing medium.

Case Study: Propagating Cannabis Seeds by Floating

These cannabis seeds were floated in 8oz white paper cups covered by a pot tray. These cups were then placed under a T5 light approximately 1ft away from the tops of the cups.

The germination of cannabis seeds depends on the right amount of heat and moisture (NGA, 2018). Since viable cannabis seeds float on the surface of the water, they are able to retain the proper ratio of moisture and air. Seeds that do not float may be sterile or underdeveloped. When you roll the seed in your hands prior to floating the seed, it should be firm and brown with the occasional dark stripes in appearance. Immature cannabis seeds appear green or sometimes white and as stated above they will sink to the bottom when you attempt to float them.
