From a fellow grower: What will happen if our non-auto Goldleaf gets 13 hrs light and 11 hrs dark-ish (they get ambient light from parking lot). Will they flower or do we need to block ALL light for a solid 12 hrs?
It would be better to block all light if possible.
I’ve seen instances where residual parking lot lighting has caused hermies. Sometimes only on 1/2 of the plant.
Any way to put something up on the side of the plant facing the light ?
Good question as old guy mentioned I think it’s about a 50-50 chance that it could hermie. One reason I say that a few years back I had it happen to me from a street light. Mine did flower beautiful plant it just hermie. I would block the light if possible.
