will I have heat problems??? HELP!

My grow room will be 5.59 ft long and 3.28 ft wide and 4.92 ft high. going to use a 400w hps. will I have heat Problems? and if s what sould I use to cool it down?

If you close your "doors" on the grow room yes, it will overheat without some way to vent out the excess heat. Summer time in S. Africa?

Oh yeah, to cool it down use a good bathroom fan, exhaust through the cieling or keep the grow room doors open with fans a blazing!

At least use an oscillating fan with the door cracked open ....

ok but If the door has to stay closed?

Yes gets temps are about 18-35 in day and 8-15 in night

I have a similar cabinet, just a little smaller. In order to keep those doors closed, you are best to put an exhaust fan in one of the top corners( 120-150 cfm in line fan or squirrel cage). Then in the opposite bottom corner drill/cut an intake hole at least as big, if not twice as big as your exhaust. by doing this I am able to keep my temps under control. you may have to play with the intake size a little to get the temps where you want them. I started with 1 2" hole and added a cppl more, one at a time, until the cabinet cooled down enough.

Hope this helps
Good luck, good grow
