Little Old Lady

Hello all,

I am looking at getting a Air Cool Cylinder from Inside Sun. I have a couple of questions. What is the difference between the 20 and 24" cylinders? I have 400w HPS, does it make a difference? They are both the same diameter, why would someone want one over the other?

I am growing in an attic, using one of those "Whole House" fans to extract the hot air, which does not help enough. I am hoping to install an exhaust fan and blowing it across the bulb in an effort to get the heat down.

If anyone has ideas on other ways to cool the area please speak up.

Thanks,
LoL

they way over charge you for those things. and they dont give you crap with em. just a glass tube and a reflector.

check ebay, last i saw there was a cootube /w inline fan for right around 100$

S.S.I.N.

i would just have 2 vents one on either side of the attic.
and a few osolating fans in between.

have all the fans blowing in one direction so the air comes in one side of the attic and out the other.
