I Recently purchased a 100 watt high pressure sodium light to grow with.... and I am not financially ready to get an exhaust system to get the air out of my grow room... The room (an attic) is rather large (about 20 feet by 20 feet and about 6 feet tall) and there is a kind of small opening where air can escape and come in. Im Growing 2 plants at the moment and i plan on letting them grow big. The air temperatures reach about 75-80 in the day and 60-65 at night Do I really need any more ventalation for this room?
