General?

Well last year i grew a few plants outdoors which two i benefitted from. Now one turned inot a hermi. How does a plant decide to turn into a hermi? And how do i prevent this?

i think it has something to do with pH level, maybe it's too low

could be from stress, could be bad genetics, disrupted light cycles............

it is usually from some form of stress, but if you grew it from bagseed, it could be in the genes, meaning it could be seed from hermies.

so if the seed is from a hermi it will automatically make the plant a hermi? I headr that hermi plants produce mostly female seeds or atleast a certin percentage. So in fact there is some sort of hermi seed?

if the seed is from hermi genetics, you can't get a male. you either get female or another hermi. that's how feminized seeds are made

exactly what johnnybgood said. its a either/or situation.
