Are there any other better ways to force herm a plant, other than with screwed up lighting or chemicals? I'd like to do it in a way that will not affect the whole plant, or the plants growing around it, if thats possible.
I've heard stories (no facts, just word of mouth, sorry) about leaving plants in bloom indefinitely. Sometimes they die, sometimes they go into rejuvenation, and sometimes they hermie. I've seen the first two, never seen it pop 'nanas.
Other than that, stress in general can cause it to pop, heavy cropping, water stresses. Also depends on it's genetic likelihood of flippin. Some just go easier than others.
A lot of dispensaries are scared of "pollen spies" working for the competition. Releasing pollen in a dispensary is an expensive move. I doubt you'll find one with it available.
