do male or female cannabis plants produce seeds

Male plants, in contrast, don’t produce flowers. This makes them less valuable for growers seeking only buds. However, they do produce pollen sacs. These small vessels create the genetic material required to fertilise female flowers and create hybrids. This makes the males extremely important for breeding new cannabis strains.

See, the vast majority of plant species are monoecious, a term meaning they possess both male and female reproductive organs. These include edible plants, such as corn and squashes, that can readily fertilise their own flowers using their own pollen.

HOW TO IDENTIFY DIFFERENT SEXES OF CANNABIS PLANTS: SEXING CANNABIS

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.

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.

However, when growing marijuana indoors, a marijuana gardener will have to “fool” their plants into thinking winter is coming to induce flowering and kickstart the creation of buds.

After 2-3 weeks of the 12-12 light schedule, most marijuana plants will reveal the first signs of their gender (they either are a female plant and start growing buds, YAY! or they are a male plant and start growing balls, NO!).

(Some marijuana plants can also be hermaphrodites, which means they display both male and female parts on the same plant)

Label both the clone and the mother plant so you know which clone came from which corresponding mother. If you don’t label them clearly, then all your effort will go to waste!

A small male pre-flower – this is what male plants look like when they first reveal their gender

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.

If you don’t have a choice of seeds, and some of your seeds may be male (like if you just found seeds) than you will want to get your plants to reveal their gender right away so you don’t have to waste time and energy on male plants.
