Flowering temperature and light strength?The strain I'm growing can get hues of purple and blue if temps low.
I don't have a AC just fresh air in. If I drop the light % 100% - 75% my temp drops from 77 to 71.
last week before harvest is it best to keep lights full or drop them and get those girls changing colours?4y ago
