Nuthing on the 630wDE CMH's though.
I did come across this though for them.
- PPFD: 1027.25 average umol m-2 s-1
- (Tested @ 60cm height over 1.2 -1.5m2 average)
- CRI: > 94%
- Kelvin: 3000k
yeah the 1000w does 2100 umol at same height for a 1.5m2 area

Have you got a grow journal going on?
na no grow journal ill do one next time round ill let ya no how this one turns out
yeah im running phillips green power
Which are the green power? I havent seen them. The Phillip's elite 945 was recommended to me by everyone I talked to so I just went with them. Expensive things for sure. I spent about 180$ for the two bulbs I'm using in my fixture now.
Not a cheap hobby for sure, but I needed something to fill my need to do something with my extra income.

CMH for the win.
phillips greenpower 1000w 400v $180 each expensive and addicting
While I like this type information, it does seem a bit unfair to compare CFL, LED, and Cmh to each other. Cmh would be the obvious winner in most ways. I'd really like to see a 630w cmh in a side by side comparison with 1k HPS
intersting
yeah im going to get a 630 cmh like luckys then ill compare with my 1000w de same strain
Someone direct messaged me with an actual side by side grow log between 630w dual bulb cmh (like mine) and 1000w HPS. Talk about an amazing read, and the pics of everything throughout the entire grow are amazing. Both lights did really well, but in the end comparing heat, density, growth, and the end product color.....yep, I love my cmh all the more

My bad, not polite to talk of amazing info without sharing the link at least. Lol

Ozzie,
Dude....seriously, if you go cmh, make sure to get the new square wave ballast. The options are fairly limited, but the Vivosun I got through Amazon had free shipping even to Alaska. 2 bulbs in one fixture? With the capability to run one or both at on e for either 315 or 630w?! Fuck, it's a win no matter how you do it, and the versatility is unmatchable
