Thanks for the help, but the problem I am worried about is that my grow room is a GrowLab tent and it is in my room which is normally below 70 degrees so I was thinking I was going to have to pull air into it and not use the air in my room.white + ,black -, green ground
instead of using one as intake just cut a hole and the air is gonna get inside because of negative pressure, that way you use 1/2 electricity with just an exhaust fan, or u can put bothas exhaust if the temp is not cool enough... my ponit is that u dont need fans to bring air in the grow room.
peace
ps.sorry for my english
I know it won't go through the tent but if I only use fans to push air out and leave a vent open for air to be sucked in by the air getting pulled out, won't the temperature be to low in my room to use the air in my room. Sorry if I am over thinking this.I dont get the issue, the room the tent is in below 70 and thats not cool enough to go through the tent...........Don't overthink to hard.......
Not trying to be rude (there is a guy in the grow room area that will answer all the electic type questions).
