Seriously....what amount of stress is going to trigger male flowers to grow on a female plant?
I know "they" say it does.
BUT
I can't say the same from my own experience. Quite the contrary, actually.
Revegging due to light leaks, sure, been there.
If a plant herms, it's genetics, period.
The ability in the plant is there, it's a herm.
That's not to say the seeds it came from are bad, at all.
Far as I know, currently, the only way to distinguish a female cannabis plant from a hermaphrodite one, is through the expression of it's flowers.
Environment or "stress" may trigger a certain flower response.
Same reason for stress testing.
There are female plants that'll never herm, whatever the stress or environment, so what about them?
And, before someone says "Rhodelization" I suggest considering what distinguishes a female plant from a hermaphrodite or male plant in the first place.
