I need some help with closet ventilation

I plan on growing around six plants in my closet. There was a light fixture inside the ceiling but I pushed it up, this left a hole that will let air vent out of the closet into the attic (I'm going to probably do this using a squirrel fan). the only problem I have now is how am I going to properly ventilate fresh air into the closet. I wont be able to leave the closet door open because there will be times when the plants need to be in absolute darkness. My closet door is completely flat, no vents, and folds in the middle when its slid open.

Any advice?

just opening the door to the closet a couple of times a day will let enough fresh air in i have did the same thing with only an exhast for heat

As long as you have air going out there is air coming in. It'll come in under and around the door mostly, and that's good enough.

what kind of lights are you planning on using ? hps will get very very hot and even cfls get hot when you have enough wattage to make them worthwhile .
you will probally be ok with a 250 hps if you got a powerfull fan sucking hot air out the top into your attic and pulling in colder air through the cracks door etc .id also have a big ass desk fan blowing on the the plants , it also helps stop dead spots in the air circulation

well i'm actually going to be using two different closets that are identical in size and structure..they are each 2' wide, 4' long, and 8' tall.one is going to be for vegging and one for flowering. in the vegging room i was planning on using a 250w metal halide. in the flowering room i am going to use a 250w hps. how many plants do you think i can grow in one closet(with a fan sucking air out through the ceiling)? i am worried that with too many plants there is not going to be enough air for them to share.

man,be careful,i had enough ventilation but four of my babies died whit out a ventilator,also had HPS and they get really hot..good luck

i would look into SOG or SCROG , these growing methods imho suit a 250w best ....check this thread out for inspiration . http://www.icmag.com/ic/showthread.php?t=22192&page=1&pp=15&highlight=250+hps
