Hey guys, my cannabis grow room is too hot from what I have read, it's sitting at around 90deg f. How can I reduce the temp? I have 1 large fan swaying side to side on the plants to help keep them cool, should I add maybe another 1 or 2 more fans?

Ideally you need to build some lungs - fresh air intake and exhaust (the exhaust gets rid of heat buildup).

Alternatively, some people use air conditioners.

if possible leave door open for a couple hours, then shut it for a couple hours, then open it back up before the lights go off ! thats what i have to do for my 1000w light in my 5x5 tent... it will atleast get the temp down to 80-85 depend on temp on the outside!

Get a 20-inch box fan at WalMart for $15. Take 2 feet of rope and make a loop around the fans handle at the top.
Hang that loop on the top corner of your grow room door. Heat rises and you want to blow the hotter air out of
the room. Hang it high and make sure you have the fan turned to blow, not suck.

This sounds like a very good idea, don't know why I didn't think of that, thanks
