Male and female plants look identical during the seedling and vegetative phases. But, as they begin to transition into the flowering phase, plants finally begin to reveal their sex. During this time, females produce resinous buds loaded with cannabinoids, and males form sacs filled with pollen.
“Banana” hermaphrodites get their name from their physical characteristics. Instead of producing separate organs, they develop a bare pollen-producing stamen within the female flower. This naked appendage drops pollen directly onto buds to ensure self-reproduction. These stamens share a similar shape and colour to a certain tropical fruit, hence their name.
HERMAPHRODITES: WHEN CANNABIS PLANTS BECOME MONOECIOUS
Cannabis belongs to a minority of species that are dioecious in nature, meaning they produce separate male and female plants. Specifically, it should be noted that only 7% of all angiosperms (flowering plant species) possess this rare and interesting trait.
A guide to differentiating between male, female, and hermaphrodite cannabis plants.
When you grow cannabis plants, they will either turn out as females, males, or hermaphrodites, meaning a hybrid of the two sexes. Knowing the difference between the three is vital to maintaining a strong growing operation, whether you’re planning on crossbreeding strains, maximising the yield of your female plants, or studying each of the types.
That means you use an electric timer to automatically shine your grow lights for 12 hours a day, with 12 hours of uninterrupted TOTAL darkness during the plant’s “night period.”
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.

So all strains of cannabis that respond to light in this way (where the light period effects what stage they’re in) are called “Photoperiod dependent” strains.
Regular marijuana seeds will be 50% male, and 50% female. That means half of the seeds will be unusable as far as growing buds.
