cool tubes for vert growing?

[gualapa]

I'll be doing 2 stacked 1000w hps's. Should I go with some cool tubing?

Or could I go bare lights but still having ducts? like this: http://i.imgur.com/E2stNpu.png

If you're going to stack 'em, consider the Dual Air Cool Tube, comes in 48" & 60".
Has two movable fixtures within for perfect light placement.

ok, only thing is i'm going donut style and the dual air cool tube has a reflector.

I could also go bare bulbs
