I try to keep my temps in the summer time in the mid 80's when the lights are on with about 50 percent humidity. Night time in the mid 70's. This time of year and during the winter I like mid 70's during lights on and low 60's lights off in my flowering cabs. When it gets about 2 weeks from harvest i'll drop the humidity in the grow areas down to 30-40 percent. My veg room stays in the mid 70's year around.
