I just recently turned on my 400w MH (AgroSun). I hit high temps...like 90-94 and I am freaking out. I have a fan that should be bigger than what I need for the size of my room. Let me break it down first.

My entire grow room is 3x7x7. I have two seperate rooms. The veg/mother room is 2x3x7 and the flowering room is 3x3x7. I am using CFL's in the veg/mother and the MH in flowering. I haven't started flowering yet...just getting the plants use to MH before flowering around christmas. Right now the entire room is open, as I am putting up the wall of seperation sometime before flowering. I am very worried now, but I can't imagine what the temps will get up to in the flowering room once it's closed off...maybe better, maybe worse. Any suggestions, other than the obvious...buying a bigger fan. Not quite an option right now, as christmas has me low on funds?

I know I will be getting a bigger fan before summer, as it is like 7 degrees outside right now, and when it is 70 in summer I can only imagine what my new oven room will be like.

Any help would be much appreciated. Thank you in advance.

P.S. - before turning on the 400w MH my temps were a constant 76-78.
