If you saw on my "temp increasing" my grow room temp has been increasing. i have direct ventilation from out side right now ( pics below) but i want to use venting pipes to air cool my lights and so i can start using CO2. i put all my plants under one light (1000w mh) instead of two and turned the other one off. this decreased my temp by almost 10 F and now they are around 75F. I need to know if i should have one pipe going through both lights and sucking air from the ceiling or if i should seperate it. will one 6 inch vent be enough air to cool my room (with air cooled lights) and refresh the air? do i need an exaust fan as well as an intake fan or just an exhaust fan? please help me, any info you can give me would be great. thanks ----- my grow room is 7' x 9' x 8'
