I think that cool tube straight six is gonna be my best bang for my buck. Man, $52 and free shipping. I'm all about it.
hell yeah! htg has the best prices on just about everything. and if somethings too heavy and the shipping throws off your order price, go to there ebay and itll most likely have free shipping.
Saved me over $20 alone when i bought my carbon filter/fan combo that weighed a hell of alot. And occasionally theyll have prices on there ebay acount thatre a few bucks cheaper than there store site.
As for footprint, ive found that my air cooled hoods spread about the same, except for my euro air cooled hood thats super skinny.
I like the cooltubes better because i grow in tents and, although sturdy, when youve already got a carbon filter and fan hangin from your tent id rather have a light glass cooltube than a heavy metal one.
If i was growing room style,with thousand watts id probably go with the metal air cooled ones. Just because they spread light better for 1000watters.
