I was kinda curious how these outdoor grows that far north were going to finish out. This has been a hot arse summer here. 20+ days of 90's and above. The temps are not horrid but when you combine it with the humidity the heat index goes 104-108. They even delayed the start of school several days because of the heat. I would probably try it with an auto or fast finisher but I wouldn't expect much here outdoors sans a green house.
