This is my first closet grow. Was running lights 24 hours. When I go to sleep I shut the door and it gets no more than 90 with a humidity in the low 40s. I just switched to a 18-6 and within an hour the humidity is almost up to 60 and temp around 75. I do have a fan running 24 hours but no ventilation when the door is shut. Just wondering which one is "better".
