I recently moved my grow into the basement where it is extremely cold but here is the link to my journal http://forum.grasscity.com/index.php?/topic/1271721-Indoor-CFL-miracle-grow-cabI am having trouble with temps being very low so I believe a space heater would suffice plus passive air holes and exhaust thinking about using 2 120mm PC fans to pull air through the room. Don't have the money for a inline fan so PC fans are in my budget. Should they be doubled up or have one inside the room pushing air out and one on the outside pulling the air out? Please help I'm so confused right now no problems *bongin* only solutions... yeah that sounds right
