I finally finished drying my Master Kush crop and before chopping decided to find out once and for all if dark before harvest helped frostiness or if it was just the extra time I gave the plant before death. I allowed half of.my crop two days dark before chop, and the other half five days. During the extra three days the first half still received light to eliminate possibility of extra frostiness coming from extra growing time. Despite receiving three days less light, replaced with darkness the whole part of the crop that received 5 days darkness was WAY frostier than the half that only received two.
