well here in alaska where i live Im guessing the summer climate is the same. its usually 50 on cold days and 70 on hot days in the summer with about high 40 to low 50 nights with 3.5 months of growable time. the 12/12 starts in the middle fo freakin winter so there is no way i can flower the plants independantly so to conquor this, i just stole 15 garbage cans after the garbage man dropped them off on their garbage day, i spray painted them camo and i put them over each plant at night for 12 hours. i know its alot of work but its better than having an autoflower or no weed at all (= also i strictly only use northern lights for a non autoflower and lowryder 2 /easyryder or snowryder for outdoor grows in my climate, its the only plant that can grow up here.
