yes, i always took everything out, bleached floor, walls and ceiling and basically sterilized all the equipment.

i don't have a grow currently do to 1 year probation, but when i did have a grow, my white widows would always hermie on or around week 10 of flower as did my master kush but my gypsy's kiss never had 1 hermie at all in any point of it's life cycle. because of this i have to assume it is somewhat determined by genetics whether a plant is prone to hermie or not.
