need help building copy of "mini caddy" from sunlightsheds..

[turtle420]

Dont vent the light like crazy as 75% of the energy a bulb uses is to get up to temp to run.

HMMMMMMMMMMMMM.....

I follow you... please, more input.

So... Ok, I've got a cool tube, which will get a 400W MH + a 600W HPS. I saw a figure the other day, that said you should get about 4CFM/watt.

So, my 1000Watt setup should be getting 400CFMs.

But, you bring up an interesting point... the bulb needs to be hot. ...

This seems like a delicate balance... any more input you can add?
