i've got 2 box's, each 50ft cubed. but i just can't find any fans small enough for my box, all the hydro shops sell massive fans & computer fans would surely be too small. anyone know where i can get some small fans? (in England)
cheers

Don't be fooled by computer fans... yes, there are the small ones, but there are some big MoFo ones!Quote:

I don't know if you call them like that, because you British are like super-corteous... but anyways, they're called "fart fans" because they're the fans used in bathrooms to exhasut "farted" air. Get it?
LOL! Ok, what ever... well, I got for about $15 a 50CFM fart fan... and for around $45 a 6" 90CFM one.
Hope this helps...
BTW: Buy... if it doesn't work, take it back! :D
another thing you can do is buy Inline Duct fans. I bought one for 29.99, Canadian, and it's rated at 500cfm, but cfm is cut down significantly after adding ducting. From what I can tell, you can't have to much exhaust (to a point. You don't want fans pulling your plants over)
fart fans are the shit
cheers for the help guys.
my original idea was having 4 fans,2 for in-take & 2 exhaust fans. i was looking at some inline bathroom vent fans, their really cheap & quiet, but too powerful. u can get ducting that splits into 2, looks like a Y shape. would it be efficient enough to have 1 fan for intake of both boxes & 1 exhaust fan for both boxes, if i have the fans where the hole in my wall are?
if u look at the shower fans.. u can get a 12v version.. put a variable resistor on it then u can conrtol the speed.. its reeeeaaallly simple.. and ul be able to get the temp spot on by controlling the speed 2..
One exhaust fan... passive intake.Quote:
