ventilation problems

I need help with ventilation. My grow room is in my closet, and i have a fan inside but i have no way to vent in cool air and take out the hot. Here is a diagram. There's no a/c vent, the fan at that bottom is not there. I also need to the the door closed but i no it want work that way. I can not come up with reasonable way to acheive ventilation. Can some one help me please?

Supplies:

1 rubbermaid storage tote
1 cutting tool
1 Walmart fan
Duct Tape
Sink Water
ICE
Dryer Vent



Directions:

1. Cut hole in storage tote lid
2. Duct tape fan so that it blows outside the tote
3. Duct tape edges to Dryer Vent
4. Fill Rubbermaid tote with Water and ICE
5. Attach Dryer Vent to grow Box with Duct tape or some other method

Cut exhaust hole for grow Box... you can use a pc fan with a AT PSU computer power supply for this or any other fan you wish to blow out.

You now have a home made air conditioned grow box... cheap and works... just remember to refill water and ice as needed.

Run ducts to the attic to vent hot air up high. YOu are going ot need some kind of intake. What kind of lights are you using? How big is your room? BTW Don't use tinfoil on the walls, go with flat white paint or mylar

personally I am a fan of titanium white and elastomeric white
