female cannabis plant producing seeds

There is a good reason why most growers keep male plants away from their ladies: Pollination from males causes the females to develop seeds. As a result, females focus their energy on seed production, rather than on growing you some fine-quality bud. This seedy and unfortunate final product can be avoided by implementing a few basic techniques.

A good test to see whether the bracts have swollen is to take a pair of tweezers, grab one bract, and open it up. If there is a seed inside, you have a pollinated plant.

HOW TO TELL THAT A FEMALE PLANT HAS BEEN POLLINATED

Pollination of your female cannabis plants will make them produce seeds and spend less energy on producing quality buds. But when you recognise the signs of pollination early, you can avoid putting time and resources into a poor harvest.

To determine the sex of your cannabis plants, you will have to wait until the pre-flowering stage when plants begin to put their energy into reproduction. Female cannabis plants show their gender signs later than males. At the location where they will soon grow their buds (the nodes between the stalk and the stem), females will show wispy white hairs.

Female plants usually take several days longer than males to develop pistils or female sexual organs. The pistils look like small green seed pods and have white v-shaped stigmas, or thin hairs, which extend from them. Female plants are generally shorter, denser in foliage, and broader than their male counterparts.

To a non-expert grower, all cannabis seeds look alike. The gender of cannabis plants becomes more readily apparent when the plant approaches the flowering period .

A true female cannabis plant cannot be cloned from a male plant. Cloning is a process that is used by breeders to make genetic copies of robust, healthy female plants, reducing the guesswork that sometimes accompanies cannabis cultivated from seed.

Can you turn a male plant female?

“We found that it is better to remove the entire plant than cutting off the problematic branches,” explains Perlowin. “We do this by using a large plastic bag to cover the entire plant. Without shaking the plant, we move the bag down to the very bottom of the plant, seal it, cut the plant down at dirt level, then take it off the property.”

When female plants herm, or develop male flowers capable of disseminating pollen, the entire crop is at risk of pollination. Female flowers that have been fertilized by pollen will halt their development to produce seeds, limiting flower production.

The sex of a plant is determined by its genetics before germination even begins. With the sex genetically encoded, there is no way to make a male plant female, or a female plant male. There are techniques that can be used, however, to encourage a male plant to display female characteristics. These techniques require the use of chemicals, such as ethylene , to prompt a hormonal response from the plant.

Like all plants, however, cannabis has an inherent drive to procreate by propagating seeds. One way that the plant achieves this is by herming, when female plants become hermaphrodite to self-pollinate. The tendency to herm means that growers must take extra care to minimize any stressors that may cause the plant to perceive a threat and change its sex.

Every plant grown from feminized seeds will produce the buds we know and love. This plant was grown from feminized Swiss Cheese seeds.

But is there a dark side to feminized cannabis seeds?

letting buds over-mature – this is also known as “rodelization;” basically when the plant’s buds have gone past maturity without being pollinated (if the grower waits way too long to harvest), a female plant may make male pollen within its buds as a last ditch effort to pollinate itself and make seeds for the next generation

bad genetics – the plant comes from a line of plants that naturally create hermies for no reason, even in good growing conditions

The pollen that results from chemical stimulation is used to pollinate another female plant and make feminized seeds. If the parent plants would never hermie without chemical stimulation, then you have created feminized seeds that won’t ever make pollen in your grow room.
