light durring the flowering cycle will fuck it up and possibly turn it hermie......now with that in mind.....i have no idea how much light it takes to fuck it up, whether its the amount of time it was exposed to light or how much/what spectrum light it was exposed to. I'd imagine the only light that wouldn't have an effect would be an all green spectrum light with no other color in it. IDK though i have never tried it
sorry for all the typing haha
bottom line is if your plants have been exposed to light durring the photoperiod there is a possibility it will herm out on you. Just dont expose them to light and you wont have to worry about it
Avoid light leaks during flowering. It must be completely dark during the dark period, with no interruptions, even for a minute or two. Apparently, green light is okay, but even then, i would only use it in small doses, when there is absolutely no other choice.
Trust me, you don't want your yield halved, just because of a light leak causing a hermie.
