I think cheep leaded glass is real good. I think the cheaper glass got more lead in it and thats good for the spectrum. Somethin like that anyhow. I know I remember somethin like that.

Untempered lead glass has a higher refractive value than borosilicate (Pyrex) glass.

1000 watt CMH
1000 watt CMH
I would expect with all the 1000 watt HPS parking
lot fixtures out there that it would be in Phillip's best interest to get
a 1000 watt CMH to the replacemnt/upgrade market;
especially if CMH output is in the vicinity of 140,000 lumens;
or about equal to a regular hps but with better color rendering
for showing off fancy parked cars.
the lumen maintenance is important for parking lots; so it's got
to be up there with hps or the market may pass on the CMH.

hoosierdaddy said:I would also be thinking the light is causing a deficiency to accelerate. Only problem with that theory is that I am only seeing the purple effect on the sides of the branches that face the light. The other side of the same branches are green as can be. It is apparent that the purple is only where the CMH light hits the plant. Buds facing away from the light are not seeing purple either. This brings me to believe it is much more light dependent than strain.
And Like I have stated before, I have a cut that was grown only under HPS and there was no signs of any other color but green. Same cut under CMH got lots of purple.
I am not a purple freak, and I see nothing special about the color, other than it brings a certain level of sight appeal to some.
THis is a bud from the cut I spoke about. You can clearly see how purple/black the stem is under my thumb...the other side of that stalk is green.
You can even see in this shot where the green line meets the purple.
If I showed the other side of that bud, there is NO purple whatsoever on the side that never saw the light directly.
Look close and you can see this side of the stalk at the top where the light was blocked and a clear indication of shadowing (green on purple).
So far, I haven't had any of my plants, other than the leaf stems, purple like that. But, then again, my lights-off temps are about 65F. I stumbled upon the following chart and happened to notice that the only two things that might cause your plants to purple like that, would be an N and P deficiency. However, if, all things being equal, the only difference you are providing in an optimal growth environment is the CMH bulb, would a plant "out-running," as it were, what it needs, make it appear as a deficiency? Your leaves seem to be healthy and green, so, I would tend to exclude an N deficiency. But, since I am not a plant biologist, I feel it is entirely within the realm of possibility, that the CMH is a bit like steroids for plant growth, thereby, causing an extra demand for certain elements (varietal specific, maybe?). I don't know, if such were the case, why it would only affect the parts exposed to the quality of light the CMH emits, but, maybe this can serve as food for thought. lol...I know...hardly scientific thinking, but, while buzzed, I can come up with some really off-the-wall thoughts.
Namaste, mess

Absolutly. I couldnt have said it beter. Thats exactly what I think I been see'in. Thanks alot for the chart! Mabey the purp petols indicate a p def? My mom's got every indicator on the chart for a n def. My petols are purpt up too.messn'n'gommin' said:So far, I haven't had any of my plants, other than the leaf stems, purple like that.

Some may think this as off-topic, but it all goes back to the CMH and how much better a lamp than either, or both, the HPS/MH lamps.
I found this under the "Terpenes and Phenolics" page...
Phenolics
Phenolics are a huge and diverse group of aromatic compounds (containing benzene rings) usually with hydroxyl groups. Phenol itself is the simplest member of the class, although it is not found in plants. Many plant phenolics have three carbon side chains and are called "phenyl-propanoids". Hydroxy-benzoic acid is one of the simpler plant phenols, whereas coumarin is a simple phenyl-propanoid found in some grasses.
More complex phenyl propanoids include the flavonoids (C6-C3-C6). The pigments in red, blue or purple flowers are usually flavonoids called anthocyanins. An anthocyanin is made up of an anthocyanidin with one or more sugar molecules attached.
The flavonoids also give a bitter taste to many plants and plant extracts (fruit juices) and form part of a very complex group, the tannins. Tannins are extracted from tree bark and get their name from their use in the tanning of leather (they are also present in tea).
Probably the most ubiquitous of the phenyl-propanoid derivatives is lignin. This is built up by the random polymerization of C6-C3 units and strengthens cell walls, particularly in the xylem of woody plants. It is a huge molecule that is interwoven with, and chemically bonded to cellulose. All kinds of linkages occur in lignin and it is not possible to show a complete structure.

This tells me that plants that are prupling under the CMH is normal and (extra?)-healthy. Hoosierdaddy seemed to know this on an intuitive level.

Hey, FreezerBoy, I had to take some time off for a while. I have been watching everything here on and off for a while and really felt inspired by the freezer idea. I had to discard my old rickity cab. So I grabbed an old freezer and built it up with one of my 400w CMH sets and a Building control computer. It is still a work in progress, but I wanted to say thanks for the inspiration. I have a thread in the DJ/Legends vendor forum with JohnnyBlazexSweetBlue(m) going in it. It is serving the tasks well.
Anyone questioning the full spectrum lighting of the CMH should check out my stem girth and compact growth with that much CMH in a 19 cubic foot cab!

az glad to see u around again here..
saw ya with sp.. i love them Pricing is an issue but i like the results..
on my girls here just harvested .6Lb Dry off a 250cmh in a 2 gal SP. (watered every other day, unless moisture meter went dry.)
(2nd grow for her.. im kinda impressed)
cscc.. im thinking you really need an air cooled hood in that footprint.. id kinda go a 250..
as far as the purpling goes..
as long as its not a Def..
i wouldn't worry about it..
infact like others id have to say i like it.. (my peppers always purp under cmh at the stems and fruit site when hps not so much purp)
side note the sugar /flavor content from HPS vs cmh in the peppers we grow with same nute reg.. we now use very little Bcuzz Flavor-c AKA Molasis even less as time has gone by using cmh..
even hardens it my mind full spd makes more internal goodness in the fruits Wether eatable or smoke able
i will say you cant us crap or over priced nutes with cmh the organics (bcuzz bio-nrg) and GH dry Maxi with silica, flor plus thats its.
organic is the best way IMPHO.. im Def convinced of it..
can over feed and NO Nute burn..
Last week just for chits.. I mixed up 1.5 cups growth-c and bloom-c with 4 gal of water and watered 10ish plants and they still going strong..
i typically say use at bottle doses but if u go higher no real risks..
(higromite & bcuzz bounce cococ 50/50) or organic soil, higromite 70/30)
i haven't phed my nutes in oh dam.. so long my hanna ph probe dried out LOL Freek there's 40 bucks to replace..
the only probs with my garden is Temps are way to cold to flower nicely and the day night is 30 drop.. even 2 hours ago the 400 in 3.5x4 was to cold..
(currently slowly revamping grow room from full room 15x22, now 3.5x4, and soon 6x15)

Just added a 400w CMH to my Veg lab. 1600w in the flowering chamber. Total of 2000w of CMH running strong!
Ive got a light mover, I am going to hook the 400 up to. Won't be needed until next week, when all those plants on the shelf, get put into 5gals.
CMH is your shit. period. Cheaper, last longer, grows better shit.
if you look close, there is even a PAR30 phillips master color, in the light socket!

I'm seriously thinking about 8-10 400/CMH's, instead of 6x600 or 4x1000.
Going to cost more initially, but within the range of recoup from cheaper bulbs after a few changeouts it looks like. My new 40amp timer/50amp breaker will handle 4x1000, looks like it will handle 12 400's with triple T expander plugs.
It'll look like a fire danger "Don't do it!" poster, but should be solid lol
These sure look & sound impressive.

Do it! 4000 watts of CMH would be insane!
Your plants will thank you for it. Your light placement will be more versatile, and cover more.

I just might 
What kind of light pattern would you say I'd get with a 400cmh & these ArticSun reflectors? 18 1/8" x 15 1/4" x 8"
My 600/Aurora 6's throw a tight 3'x4', been forever since I've run a 400 & never a cmh. Those ArticSuns are a bit wider/more open, which should be perfect for weaving a bunch together.
Thanks a bunch
