Yeah, we probably wouldn't go 600; maybe 250 to veg and 400 to flower with a photo. You are right, it may not be as expensive as I think. But it would really suck if we opened our electric bill and had a really high bill. I know a guy that lives just outside of Austin that has a little shed in his backyard that he grows in. I think that he runs several 400 lights that have ballasts built into the lights and he claims that his "growing shed" only pulls an additional $20.00 per month. I find that pretty hard to believe but that is what he claims. Like I said we are still kicking this around. Just curious though, if we did covert over to HID, what ballast/bulb combination would you recommend? It would be nice to use just one bulb throughout the entire grow, from veg to flush, but I am not sure if something like that exists. Back in my day, just after the Earth cooled, if seemed like you had no choice but to switch out bulbs from MH to HPS. Today, I am sure that growing is a completely different ballgame. Thanks for your advice and sharing your knowledge.
). I do have to say CMH does look really good though, 1 bulb start to finish and 315w at the wall that will hang with 600w HPS from what I've heard.
