It would likely not hermie if it wasn't exposed to those same stressors again. But as growers, we never plan on things to go wrong...we rely on the genetics to be strong enough to withstand environmental stress. So, when you get a strain that hermies from stress, the question becomes whether or not you want to roll the dice on whether or not you will have a good, stress free flowering period, or risk running into some problems and BOOM...your tent is full of hermies. I would prefer to go back, select a new stock of genes, and improve your statistical chances of success.
