Ventilation

So I will probably be using a 400W HPS in a 30 inch wide 70 inch tall closet. What would be my best bet for ventilation?

closets are tough if you dont have an attic above them. i got lucky and had an a/c duct above mine and i tapped right into it

What if you have no ventilation? I have a great fan keeping the air moving around inside the closet. But my only way to ventalate is to open the door a few times a day and point the fan out... My temperature is 93°

Thats too hot. They will grow but they will end up stretching a lot. I would cut a hole in the ceiling or somewhere with a fan getting rid of the heat. You will need a way to get fresh air in while the exhaust fan blows out.

How about this: The grow closet is in my bedroom which is in the basement. The whole house has central AC. If I keep the door to my closet open, and the door to my bedroom closed the AC should regulate the temp in the bedroom and the fresh air can be directed into the closet via a couple strategic fans!

For multiple reasons I cannot drill, cut or blast holes in the ceiling...

Edit: When flowering time comes, 12hr on / 12 off should be a "short" enough time to keep the closet door closed to exclude bedroom light. Also maybe the added heat will produce more resin?
