just one thing: i just finished 2 weeks ago my third (last) cycle with CMH. No photos for security concern.
IMPRESSIVE results, that's all i have to say

so, you're growing all along with a CMH and no HPS for flowering?

its a 400w mh ballast, and a 600w hps , inside one ballast, basically two outputs in one ballast, if they came out with a 600w cmh id probably be able to do it

yes.
From seed to bud.

My apologies for being so unclear smokadepep. I meant that if the power cord to the MH socket was not proprietary (i.e. it is instead, a male 3 prong plug), it might be possible to unplug the MH side of the Sunsystem and running your HPS ballast to the unused MH socket for the CMH and running it alongside the 600w HPS.
Namaste, mess

800w CMH = 632 Grams in soil
Next run I know I will get 800+ Grams and surpass the 1/1 gram/watt ratio with an additional scrog and clones of 1 know producer.

Smoka, im not following ya..
Smoke, aquarium hood would be best for footrpint but making one is easy.. (check some of the PC growers reflectors)
Gram good to hear..
Fid, Yups CMH seed to death
Micro, NICE i was waiting for you to chime in with results..
How potency (Super Dry a Nugy out tell us.. *harshness is acceptable to get max Effect as needed to be super dry to make thc good (short version)
Great though im just constructive criticizing a bit.. sorry..
satori check my sig..
cmh link and then last lamp on the right.

Ya...you can use it that way, but be forewarned, they can burn out quickly. Up to 4 times faster, it not quicker, than their rated life. Here are a couple of links where you can get either the horizontal or vertical bulb. Prices are as cheap as you will find just about anywhere and stealth shipping.
The 250w and 400w:

The ED17 here, 50w, 70w, 100w, and 150w, are rated universal.

Hope this helps.

does cmh run on econo light hps's??
If your econo light is a 250 or 400, maybe. Any other wattage NO. Open your ballast box and look for the ANSI code. S50 is for 250, S51 is for 400.
hey guys i was searching online for a 150W CMH and found this:

anyone have opinions on which 150W model would be best suited?

CMH is the way to go...so i have a question I am on day 6 of flower and my PPM is 900 and my PH is 6.1, now is this a good range to be in.....
My temps with the light off is 60 degrees....

where they fit... heat wise
where they fit... heat wise
it's been said that the run a lot cooler than standard HPS so could one run a 400w CMH in the same cab/tent where there was once a 250w hps with the same temps???
What about glass, does it alter the effects of the bulb investment? It'll take some UV away but what else. I mean with the glass the bulb can be RIGHT ON TOP OF them, can the same be done w/o glass with a CMH?
Need to know this!!!
How type of increse shold one expect from a 400wCMH vs Standard 250? Like worth getting a whole new light system for it. (My grower runs digital)

CMH runs cooler watt for watt but, you're talking about near double the wattage. I went from 150 hps to 250 CMH and temps climbed like an easy bake oven. Doubling my intakes cured the problem.
I don't use the glass and I'm right on top of the canopy. I've seen some 400s get pretty close.
I grew happily with the 150 hps for years. One grow with CMH and I'm never going back. Recently cloned a T*Haze x Skunk#1. The donor lived it's whole life under CMH, it's clone was started and spent the first 1/2 of it's life under the HPS. Now under CMH, the clone is stretched out, sad and puny compared to it's mother. No more HPS for me. It's "night" in the cab now, I'll try to remember to grab a photo tonight during the "day."
You don't need to replace the entire system, just the bulb and ballast. Possibly a new ballast box as well. Those magnets get pretty big.

i'm not sure but....
... has anyone noted a decrease in potency? Or is it just my imagination?
I should do a side by side with clones... but for me it's impossible...

While I haven't smoked any of the new grow it looks as trich laden as it's mom. It's just lesser growth in the same time period.
FWIW the clones, taken 3 weeks into 12/12, never revegged, even after 2 months in 24/0 they were still into assymetrical stemming and showing (tiny) flowers in new growth. When I cloned THAT clone, it went straight into 12/12 under 150 HPS. The original mom was from seed under 250 CMH and had a few weeks of vegging. What all that means, I don't know yet.
