Cannabis growers and breeders use this trait to their advantage, since it allows them to separate male and female plants. This enables them to prevent the flowers from becoming fertilised and going to seed, which results in better quality flowers, known as sinsemilla.
Of course, growers want to avoid this phenomenon if they’re aiming for the best flowers possible. We’ll dive deeper into what causes hermaphroditism and how to avoid it below.
MALE VS FEMALE CANNABIS: WHAT’S THE DIFFERENCE?
During the early flowering stage, take a stroll around your grow room or garden with a magnifying glass or jeweller’s loupe. Inspect a few nodes on each plant to see how far along into the flowering process they are. At this stage, you won’t see any obvious flowers or pollen sacs. Instead, you’re looking for young pre-flowers. Although these tiny structures look similar, they have distinct features that allow growers to tell them apart.
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.
The ability to determine plant sex as early as possible is a critical skill for cannabis growers. As you develop this eye for identifying plant sex, you will be able to prevent any accidental pollination.
18-6 – 18 Hours Light / 6 Hours Darkness each Day
24-0 – 24 Hours Light / 0 Hours Darkness each Day
This is done by changing the plant’s light schedule to 12-12, where the weed plants gets 12 hours of light a day and 12 hours of total darkness.
If a female plant is kept in the vegetative stage long enough (the length of time varies depending on the strain and conditions), then she will start showing the first sign of female hairs even before you move the plant into the flowering stage by changing the light schedule.
What they found is that a marijuana plant will stay flowering as long as she gets 12+ hours of darkness on a regular basis. The length of day period didn’t seem to matter at all. In fact, you could give plants 12 hours of dark followed by 24 hours of light, on a regular basis, and plants would continue to flower as long as their darkness was uninterrupted for 12 hours at a time.
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.”
