I am in need of advice on the best way to vent my closet grow. It is 2'x5' with a 8' ceiling and double doors. I am currently using a 6 plant bubbler hydro system. I was using cfl's for vegging but I bought a 400 hps light an threw it in there and now my temps are running high.I own this house so cutting holes is not a problem. There is a attic above the closet so I can run a vent up there. I am thinking of putting a vent down at the bottom of 1 of the doors or should I put a vent in each door? I guess what I am really wondering is what type of fan should I use for exhaust?I would like to be able to get everything at either Home Depot or Lowes and also do this with in a reasonable amount of money.Also I would like to be able to keep the ballast in there also (it doesn't seem to run hot anyway it's just slightly warm). I am using a small oscillating fan to move air on my plants.Any help and opinions will be greatly appreciated
