Do you need to have intake and exhaust on a cool tube? I just purchased one, and a 6" 240cfm fan to suck the air out of the tube. Is it more effective to have another fan on the other end pulling air in?
cool tube question ...

I Have a 400w hps with a 200cfm 4in inline fan-filter. I think if you have any bigger of a light you need a 6in fan not a booster fan all though that fan you have might cut it if you arnt in a closet lol.

Growing in a 6'x3'x6' plywood box in my barn. I have 2 windows open all the time on each side of the box with a fan blowing fresh air in, also I have a intake and exhaust with 2 more oscillation fans inside box. Very well ventilated...

Ok good, it just gets so Damn hot in there. Even with all my ventilation its usually 90 degrees, and that's with cfls and t8s.

ALWAYS PUSH air thru a cool tube with a fan!
If you want to pull air your fan need to be in metal.
if you pull air thru a cooltube there is a risk for the fan to melt due to the heat.
cooltubes are usualy connected like this:
CARBON FILTER---->FAN--->COOLTUBE--->OUT
or
INTAKE----COOLTUBE-----OUT
good luck

i agree. You should try not having to use a cooltube, but at the same time i must agree that it can be very beneficial.
