It is often said that high humidity, low nitrogen, cooler temps and blue light help to bring up females. I am doubtful there is any real science behind this and is strictly anecdotal.
Blaze said:Yep you are 100% correct there is no real science to support the idea that environment or any of the above conditions determines sex in plants. There have been studies done on this with other types of plants and it was found that the sex of the seed is determined when it first forms. The environment that it germinates and grows in has absolutely no effect on the ratio of males and females.
I've heard/read the same theories about how temp and humidity can get you more females but all the real science on this subject has found the exact opposite to be true. However it has been found that the environment where the seeds form may influence the male/female ratio.
Blaze said:Because reptiles are not plants. They are very different living organisms. I think this is where the myth that plants are affected in the same way comes from. Environment can make a difference when determining the sex of animals but all the studies done on plants have never found an example of the same effect on seeds.
Sex triggered by environment , how ?....deeweeb
I have read various postings that state different environments will trigger the sex gene within a seed to produce a male or female plant....deeweeb
I thought the sex of a seed was predetermined in the gene and the environment has nothing to do with changing things as far as sex goes ....deeweeb
Are seeds "bisexual" so to speak , with both sexes contained within the one seed ?....deeweeb
Sexual expression is phenotypic. That means all the traits possessed by an organism that can be visually observed; but it also encompasses all the traits that can be made to manifest by manipulation or stimuli. Whether it appears to be 'male' or 'female' is condition dependent.
Here's the deal: ordinarily the environment shouldn't have such a profound effect on a seed, but irrespective of what they appear to be phenotypically, most Cannabis plants are genotypically intersex specimens (colloquially referred to as hermies).
That's just the way it is.
