Q: Does growing many feminized plants together causes some plants to turn hermie?
Plants do produce pheromones to communicate with each other. But I don't think that sinsemilla plants signal to one another that they basically need 'a man' to fertilize them. We have never seen anything pointing in that direction.
We can however say for sure that the plants grown from our seeds are not stimulated by other female plants to grow male flowers. Not even if you grow them together in a big room full with only female plants.
Plants grow male flowers when they are genetically predisposed to do so (male plants and genetically hermie plants.) We strongly select plants on not having hermie tendencies. But there is always a small change that when under enough stress, that some plants may grow male flowers. But this is NOT normal and healthy, well grown Serious' plants shouldn't do this.
When female plants are stressed to such a degree that they 'think' that their life may be at stack then this could happen. As a result from the stress they grow a few male flowers. The male flowers produce pollen to pollinate the fem flowers at the same plant. Just in order to grow self fertilized seeds. Producing seeds from male and female flowers at the same plant is a way to have their genes survive. Making seeds by totally producing them yourself is better than dying without any off spring.
This self-fertilization has proven to be successful in the evolution of the cannabis plant and as a result it is present in the genome of cannabis. That is the reason that when plants are stressed and 'think' that they may not survive, that this can stimulate plants to grow male flowers to produce their own seeds.
But it doesn't matter how many fem. plants are around them. Plants do this on their own and independent of what is happing to other plants around them. One plant can grow male flowers when pushed under certain circumstances to do this. Bad circumstances can force plants to become hermie. Breeders should never use plants
But plants from our seeds usually do not go hermie, even when under stress. We select our parent plants heavily to not do this. I cannot say it is impossible for plants from our seeds to go hermie, but it certainly is rare.
