I got mine at The Home Depot.

It cost $78.00

Arent you growin indoors?

Remember the A/C units creat heat as well. Gotta have that vented out.

If you're indoors and you getting heat problems now....you need to vent more heat out. What kinda heat extraction are you running?

Now that its hot outside, in the garage and in the grow room, the temps are over 90 F.

In fact right now, 11:32 its 91.2 F

But I have major fan action and major heat extraction going on, and it feels good to me.
