Looks like just us? Only during the flower stretch, first 3 weeks of 12/12 do we try to keep the temps tighter to reduce stretch. If you want to bring out the plants response to temp change, do so and watch the trichomes swell.Ive always read you want to keep daytime and night time temps about 10 to 15 degrees different. This would mimic nature as it is warmer during day light hours and cooler at night. Seems like a no brainer to me.
