Trying to find out if the air intake coming into my grow room HAS to be from outside? My room is in my basement which is already very cold down there and I had the air intake coming directly from outside. However, because it's freezing cold outside I'm getting ice buildup on the pipe and fan housing. Until warmer weather hits, can I have the air intake coming from the basement and pulled into the grow room? I need it in order to maintain levels temps and keep them from getting too high. I'm in the veg stage right now...
Thanks for any help!
