so ive recently stated an indoor grow in my closet(what would be a washer and dryer closet), and i cant for the life of me get a stable temperature. i have a small 5" fan bringing air in, an 18" fan blowing around the room, a small fan in the ceiling sucking air up, and an ac duct pushing cold air into the room. the light is a 600 watt. and the room dimensions are 7' x 4' x 4'. the walls are covered in foil until the roof. the thermometer is right next to one of the plants in a square paper contraption so its not getting direct light. the temperature has ranged from 66.9 f to 91.4 f. while i am around i can open the door or change the ac tempt to keep it at a relative heat, but when i go to sleep or leave i cant do that. i woke up this morning to 91.4 (bad i know). so thats why i am here, any suggestions? anything other variables i need to account for? the door to the room is not entirely sealed so air leaks out of it. why am i getting 20 degree differnce? out side temperature?
any ideas would be great, thank you
