I have a question for you guys , my growing room is sort of outside , like if I open the door the breeze comes in and and sun light but not direct , it is 1.2 mtr by 2 mtr at 6.8 foot high , so if I was to keep it open to help with Temps would that be ok , the lights are 2 x 600 watt Leds , also I am using the lights to Veg 20/4 , now I may be wrong here , but I don't see how it can hurt , Humidity as around 50 % with door open and I have fans in there as well . :dunno: The reason I do this is to speed up the Veg time , then when the go out side they will be on a 12/12 or there about .
