Your light is THE most important factor in your grow. If you skimp here, you're setting yourself up for a disappointment.
I don't agree with that for the most part. If you know how to grow well you can get quality flowers from a shitty light. Your Environment has a bigger impact on quality than anything else.

another score! If memory serves these boost to 375 or 380 watts. Is that what the capped wires are for, can you shed any light here jhhnn? thanks so much!
Jhhnn got banned. Might be temporary?

Thanks hammerhead, lets hope its temporary.

Not Jhhnn, but I did just pick up a few of those GreenTek ballasts, and I believe the the capped wires are for dimming... at least the ones on my Philips are.
what kind of a footprint you guys get with the 630 cmh for nice vigurous healthy bushy veg?
I only have a lux meter to actually measure it. 20-30K is what Im getting. When at 630 I do 24" from canopy. I have it dimmed to 420 right now and 20" away. That gives me a 3x3 ft area.
It doesn't seem that powerfull compared to 1000K HPS, but maybe Im expecting too much magic. Afterall I am running 630 watts, 18/6 for a 5 by 5 footprint.

5x5 is what im using for 630. I have another area with about 6x4 under 2 315+200W LED.
When comparing 630 vs 1kw u want to compare GPW. This is where u see the magic happen.
I have posted hundreds of pics under CMH. I couldn't be happier with the results vs HPS.
PAR meters are more accurate then LUX. You can convert LUX to PAR.

Thanks Hammerhead, 5 by 5 for 630, sounds exactly like what I was doing. You have it 24" from the canopy to get that 5x5 footprint?
I only use it for my veg room so no G/P watt analaysis but 630 is 30% less than 1K roughly so I can see where math comes through when you look at it that way. In the bloom room I have 3K, Perpetual 8 plants go in every week for 6 weeks. Then three weeks break. So far this 630 is able to veg all those plants and keep moms nicely.
No, I have it as high as it will go. Depends how big the plants are.
I've found that a 315 in my hoods works best over about a 30"-36" area, and somewhere from 40-50 watts per square foot. 4' has been too much - the edges suffer. I would go with the 5x5.

They're great lights..
Some peeps might not know, unless i've not got far back enough in this thread, that they recently released an e40 to philips cmh socket adaptor so you can put cmh bulbs in any hood.. my thinking is to use them in aircooled hoods vertically, ya know the 360 degree glass ones and use a few quantum boards/ todogrow cobs above.
I read they were designed to be used vertically and since they pretty blue I figure that would be a sweet setup.

I don't think that's the type of vert design they had in mind. Look at the phantoms n cycloptic vert hoods, that's the orientation they were designed for, I believe your referring too. So the bulbs are mounted vertically but your still using them to grow on a horizontal plane. the vertical placement your talking about, I do all the time with hps bulbs. I am thinking about hanging some vertically bare bulb instead of with the glass shield though. The vertical position hoods kick ass though, as well as the horizontal hoods. Cmh in general kicks ass.

The independent (no ballast on-board) Sun System 315 cmh hood has a vertical orientation, and the data says the cmh are more efficient in vertical positioning of the bulb. The Sun System hood referenced has a slightly larger foot-print than the Phantom hoods.
From my records on my hard-drive, I believe this is the sku for the hood I referenced:
Sun System Hood SUN-906200

Those hoods where design for reflected light. For best results a multiple light setups is required. To be honest I prefer Horizontal hoods for flower. These do not depend on reflected light. I get better results from horizontal hoods.

Due to lack of room in my design, I'm still planning for the LED PAR 30-38 15-watt (+/-) floods positioned in corners, and angled down diagonally, but steep, (4 per area) with reflective (hardware-style shop) hoods, refitted to angle brackets, in an equivalent output of 100-120 incandescent, in 3000k to 4200k spectrum.
The reading I did stated that vertical displacement resulted in greater lumens ratings on the cmh 315s, which was why I went with the hood I did. The Phantom verticals were just too constricted in the angle of reflected light.
None-the-less, with a first-time go at (9) Ghost Train Haze #1 in a single 315 cmh in the specified hood above, and very little feed after the initial in the (mostly) organic mix, I got over 14 oz. in a 4'x4'x~6.5', dialing in new plants, new lights, new soilless mix, and new techniques.
Not my best at all, but considering the 315 acting solo, and the very good quality of the produce, I was very pleased with that run.
I strongly suspect that with better feeding regimen, same 315s and hood, added lighting LED floods as described in the corners to boost the watts/sq, ft., similar but better balanced soil, etc. I'll be seeing closer to my expected 17.5 - 20.5 oz. per same area.

Yeah I see what you mean about the hoods still being horizontal lighting whilst the bulb is in a vertical orientation within. I think them being mounted vertically shining at 360 degrees at plant level would work quite nicely but i'll just have to try it one day
