I have constructed a 32''L x 24"W x 32"H grow box, and I need to find out what's the best way to go about ventilating it. I have heard people talk about squirrel fans and computer fans, and After doing some calculation, I need at the least a fan capable of 3 cfm. I know there needs to be an intake and outtake fan. Do they need to be the same speed? And what would you guys reccomend is the best deal for 2 fans? Also, do they make them with power outlet adapters, or would I have to do some wire splicing? I would prefer a fan to hook directly up to my wall outlet. Any advice you can give me will be greatly appreciated. PS: What place has the best deals on Fox Farm supplies, and what types of Fox Farm products would I need to get? Do those same sites sell soil ph increasers and decreasers anda digital soil ph reader? -Superdragon
