Here is my little closet, what you think about that ?? Any suggestions ??

They are 39" wide, 35.5" depth and 39" height. The temperature is about 75F when the door is open and 82F when the door is closed, and the humidity is about 50-60%. I have two computer fan which run 24 hours a day to bring in fresh air from a wall. There is also a big oscillianting fan which run 24 hours. I also have two small fan which run 24 hours and which point in direction of my light. My light is 400w MH/HPS with a digital ballast, for right now it's the MH bulb and they are at 18" from the top of my plants and run 18hrs.

Could some one help me to keep the temperature about 75F when the door is closed ??

all you can do is an some more exhust like what rolln1up said, so what i would do is get a better fan to pull the hot air out. but the plants do look real good

nice clean set-up. plants look good. Is that an air purifier? are you using that to clean up the smell and does it work for you?

My flowering chamber is almost identical, although taller.

I use an aircooled hood and also a high speed axial exhaust fan.

Temps are stable at ~75F.

Is that 2 computer fan that blowing out the air on the top of the closet would be enought to drop the temperature ??

I have a similar setup but i have a 120 cm computer fan at the bottom of closet to bring fresh air in and the same size fan at the top to remove hot air and i have a stable temp of 75 degrees.
Nice plants by the way! What strain are they?

allright thanks, I found a computer fan of 120mm with an air flow of 73.7cfm, if I put two of them in my closet to blow the hot air out, is this will be as much as I need ??

yes thats right but i think you have to have the same amount of cfm blowing air in (equal amounts) other wise you may get negative pressure inside the closet i think.Its something like that anyway so get 2 12cm fans blowing air in and two of the same fans blowing out and that should do it mate.

You want negative pressure at the inlet, and positive pressure at the exhaust--or an extraction fan. Generally, pushing/pulling enough air out should pull air in.
Alternately, pushing enough air in will displace existing air and force it out. You can use fans on both the intake and exhaust, but often that doesn't work as well as you might expect and you get diminishing returns. For myself, I like to use strong exhaust fans and passive intakes.

I will also need to remove the scent of the plants, I know that the best solution is a carbon scrubber, but it's not cheap, so I would like to get some help to do my own carbon scrubber

Check out the DIY carbon scrubber thread for a cheap box-based version that attaches to a duct. There's another thread out there detailing how to build one more like the store-bought cylindrical models that can be mounted directly to a fan. Alternately, there are people building and selling them on ebay @ $45 for a 12"x4" model. That's not a bad deal.
