Well we'll see. If I can keep my temps down, I might just stick with my 600w HPS and sell the CMH bulb, so keep an eye out for a cheap CMH that can supposedly run in a high freq ballast hahaYes the lamp has been designed to work on a HPS Ballast but the Ballast is not designed to run a CMH lamp efficiently.
Its a nice experiment that You and Renfro are doing (and Renfro is a nice grower) but its a hard ask wanting to make a HPS Ballast run anything better than a HPS. And it so far shows that that's the case. This is the first thread I've seen on running these lamps so its interesting the differences that we are seeing. Good square wave ballasts are expensive so I could see a huge market if they could get a CMH lamp to run nearly as good on a Hi Freq ballast
Really, I'm happy with HPS results by far. I've had buds longer and thicker than Pringles cans and round as 2 liter bottle with HPS, so not really needing a change other than for lower heat.
I buy things I think I need, then realize after trying to make them work in my area, that I really needed something different. For instance, I bought a nice 2'x2'x53" grow tent. Its made fairly well although a little on the thin side but no light leaks. I didn't think I could fit anything longer in my closet. Well I can, so now I'm getting a 3'x 2'x53" tent, or another "2 in 1" style . Anyways, point I'm getting at is, not everything I find fits in how I expected, so I'll be reselling a brand new grow tent, never used, and possibly a 630w CMH bulb. I've currently got slightly used 240v Gavita type ballast up on eBay, no hood, ballast and 1000w bulb only. Check back for the grow tent soon, with box and everything. Only opened to setup and verify function.
