Yeah as I said I was going to buy an HPS. Was worried about the heat though. All I hear is that you have to just about air condition a small area to deal with the heat an HPS puts out.

But a 600 watt HPS would smoke all these CFL's in lumens. Probably put out around 75,000 lumes. But I'd also be on a diet of baked cannabis for a while as I don't have the means to exhaust that much heat. So heat has been the deciding factor. That and everyone grows with HID. I wanted to be different and grow the old fashioned way. Cause I'm old...fashioned.

Don't know what it costs. Like running 5 100 watt incandescents for 12 hours a day so probably no biggie.

Only have two plants but man they got some light! I've got 'em hanging all around 'em at diffferent heights. Right over all the good flower sites. Couple surrounding the top colas. Plus the 2 footer and 4 footer stuffed in there! When I open the door you can't really see the plants! HA! Have to look around all the lights.

And of course the 14 pound harvest is just me funnin' ya. Have no idea what strain. Bag seed but have torched off some growing shoots of a hermie and a male and even they gave me a good buzz. But I'm a light weight.
