What you change anything on my grow cab?

Its got a 50cfm bathroom fan on the top blowing out and a 50cfm fan blowing in at the bottom. The 250w HPS has an 80 cfm inline fan hooked up to it as well. Temps are 80-85ish. I'll be growing autoflowering dwarfs, so i think i'll be good height wise. So, think it'll work? Or, would you change anything? Comments/concerns would be greatly appreciated.

thanks,

Great, thanks guys. I just wanted to make sure I didn't have a major design flaw or forget something important. I should be starting my journal sometime this week!

thanks again,

It looks very nice.

I would make sure that it is totally light proof. It looks like you may have some light leaks around the doors. $8 in quality weather stripping from Lowes will go a long way! I'd stay away from the cheap foam/rubber stuff that has the paper you peel off the back to expose the sticky side. I've recently had VERY good results from the type of rubber weather stripping you use to seal door jams on exterior doors. Maybe get some rubber grommets to seal the holes for your power cords.

You might try removing the fan blowing air IN...you may find that it will actually lower your temps.
 
your temps are a little on the high side - 75 f is a good number to shoot for. as this is clearly a stealth grow, what are you doing for odor control? one way to reduce temp and handle smell is to put a carbon filter in line with the light and get a larger fan - something on the order of 250 cfm.

I'm building a carbon filter for the bathroom fan now, its not done yet, but i figure I've got a couple of weeks before it starts smelling. I'll try finding a beefier fan for the exhaust to keep it cool, thanks for the help!!
