This is a copy of a post I made in the Grow Room Forum... any help here would be appreciated as well!! HELP!!!!!!!!!!!!!!!!!

Hi all,
Got a question about cooling a grow room. I am certain that between the temps and the humidity that I am getting, my plants are suffering. I need any ideas on how to get the temps into a range that I can use and get the humidity up at the same time. I am hoping to find an inexpensive way of making this happen!
The room is a bathroom off of the master bedroom. Because of the fact that I have the lights on a 20/4 schedule right now, I sometimes have to close the door to the room at night so we don't have several hundred watts of light on while we try to sleep. When I have the door open, with a large fan blowing in cool air, I can maintain about 82 degrees with 35-40% RH. With the door closed, however, the temps jump up to around 90 and the humidity falls a bit. The plants are about to go on to 12/12 but I want the environment to be right for a good harvest. I need any advice about how to get the temps and humidity into the range that it needs to be, please help a beginner out!

This is the fan blowing cooler air into the room. I don't know the CFM, but I can say that it is pushing a lot of air into such a small room.

This is an overview of the actual grow area. The big fan is just out of frame to the left of the pic here.

A little closer in the grow area. Note the fan in the back of the shower enclosure blowing air across the plants and out of the enclosed area. The rags are wet and put in to try and help raise the humidity some in the enclosed area. Also, the door to the shower enclosure is never closed, I think that would make it well over 100 degrees inside....

And finally, a shot of one of my girls... BS 2 (Bag Seed #2) and the temp / RH gauge that I am using.

Again, ANY help or ideas to get these parameters into the best grow zone is greatly appreciated!

What is the ambient temp in the rest of the house? Without AC your grow space is going to ~10 degrees higher than ambient temp regardless of ventilation simply due to the immediate albedo effect of the items in the enclosure. I grew in a closet with CFLs in 100+ temps and had fine sucess (not saying I advise this but 86 durring the day wont kill em).

House temp stays right around 70 or so all of the time. Just seems that the growth could get a little stunted if the heat is too much. Also I was thinking that it may be a factor in why the one plant has always looked so droopy.... Thanks for the calming words!! LOL
