bejay - Thanks for your response, but here's the thing. I live in California and I'm growing for my sister and me. Both of us have prescriptions. I can grow 12 plants for me and 12 plants her - so I want to grow large plants.

In addition to that, I'm kind of a curmudgeon and little inconveniences tend to irritate the hell out of me. CFLs tend to present a lot of minor inconveniences and I just don't want to screw with them, at least not as a main source of light.

So I'm building this one veg cubicle right now and when it's done I'll build a flowering room. The box I have now will be for mothers.

And that brings me back to my original question which is, if I have 2 - 250w M/H's in a 3' x 6' area, is 22" is too far away from the MH lite for the young plants.

My reason for asking this is that in this small space it would be easier to mount the cool tubes stationary. But, I will do whatever is best and if I have to make the lights movable up and down, I will. Obviously, moving the lights up and down is no problem, it's the venting that's kinda tight.
PharmaCan Reviewed by PharmaCan on . Metal Halide vs cfls - some questions I've got a pretty decent grow box going using cfls, and it fits my immediate purposes, but I'm building a new vegging cubicle and I'm really wondering if cfls are worth it. Right now I have 11 - 26watt and 1- 125 cfl. Cost of the 26 watt cfls, with the socket and lampcord, were about $7.50, $82.50 total, and $75 for the 125 watt lamp and reflector. So that's $157.50 for the lamps I have, and I'd need at least twice as many lamps for the new vegging area, or a cost of about $315. I can buy Rating: 5
