Female cannabis seeds vs male

However, you may want to be more proactive and get rid of the male plants before they enter the flowering stage so you don’t have to waste the time and energy in caring for plants that you will eventually get rid of. If so, then you can use to following technique to identify and remove all the males from your grow.

When marijuana plants are seedlings (or when they’re just seeds), there’s no way to tell which plants are male and which plants are female.

18-6 – 18 Hours Light / 6 Hours Darkness each Day
24-0 – 24 Hours Light / 0 Hours Darkness each Day

Those buds turn into this!

You get marijuana plants start flowering (making buds) by changing your light schedule to 12-12.

Otherwise you must wait for the flowering stage

You don’t have to wait for the flowering stage! Below we’ll share two tactics growers use to identify gender in the vegetative stage.

A vigilant grower can carefully watch their plants and remove males when they develop the first signs of pollen sacs.

If you’re looking for more precise, science-based methods to tell your plant’s gender, there are several labs that can sex your plant right after germination – eliminating the lengthy (usually around 6 weeks) wait to learn its gender. Portland, Oregon start-up Phylos Bioscience is in the business of studying cannabis genetics, and they sell a “plant sex kit” that’s pretty simple to do, even for the folks that aren’t scientifically inclined. Simply press a cotyledon, or embryonic leaf, onto the kit’s filter paper and send it to their lab. They then test the leaf for the “Y” chromosome to determine its gender, just as would happen for a human male.

Feminizing via the silver thiosulfate technique involves carefully selecting a nearly mature female plant, then spraying it with a 50/50 mix of sodium thiosulfate and silver nitrate. This triggers a gender change, from female to male. Place this plant back with the others to pollinate other female plants, and female seeds are created.

What Are Feminized Cannabis Seeds?

In the colloidal silver feminizing method, distilled water is mixed with pure silver and sprayed on female plants. This method works best when the plants are flowering. This results in pollen sacs being formed, which will allow the seeds to produce female plants.

Separating Male and Female Cannabis Plants

How? The reason is that once pollinated, cannabis plants will cease devoting energy to growing flowers and will tell the existing flowers to stop producing resin, which translates to making less buds and less THC. That energy will be devoted to producing seeds instead. Think of the plant as a battery with a set amount of power. When that supply is spent in one area, it won’t be available for another.
