Cheap ideas for closet exhaust

I plan on growing 5 plants in my closet with cfl's. about how many lights do you think I will need? Also my closet is located under the attic but what would be the best way to exhaust to the attic without costing too much?

cfl's dont really produce that much heat so before you put an extraction in, do a dry run to see what ur temps are like

alright so you think if the temps are in the 70-85 range I may not even need an exhaust? or is it still mandatory for fresh c02?

the only problems you will have with not having an exhaust is when your plants are in flower your house is going to stink! you need one even if its just for smell.

I run 22 CFLS in my flower closet and a 150hps and i use only 2 small fans and a 6inch clip on blowing under the hps but i have to keep the room AC-ed and the closet doors open half way to keep it under 80..
