I am doing a closet grow and currently in veg state. I've been running 24 hours on. The closet I am growing in is in my room and when I go to sleep I shut the door. It usually stays cracked during the day. The temp reaches no more than 90 when the door stays shut and typically stays 75-80 during the rest of the day. The door is shut no more than 6-8 hours. I was just wondering if that is too much stress on the plant or if I should do a 18-6 so it wouldn't get so hot in there for that amount of time?
