Ceramic Metal Halide (CMH)

[Azeotrope]

Just wanted to throw up some CMH pictures. You can grow big fat donkey dicks with lots of resin under CMH. Even when your dumb ass (or mine in this case) blasts them with too much PK boost.

Below are some group and individual shots. The big girl in the middle is a Reeferman "Bonus Mix" treat that is looking and SMELLING incredible!!! Been flushing with lemon juice and molasses (very light concentration) for some time now. That is a 1 litre bottle that used to have Cannazym in it behind that cola. I have given up on counting days anymore. My genetics are solid and mostly sativa so I watch trichs and other changes and ride it out.











Some SweetBlue X JohnnyBlaze girls next. Most in straight coco or 90% coco 10% EWC and acting test subjects at the moment.










Now some CanaBiogen Deluxe mix girl. Heavy lemon scent and very Sativa. I let her grow too the bulb and get burned once or twice.






Just had to share. Thanks for looking and remember full SPD is better than lots of the "L" word!!!

Thanks Simba - I will take it to the store and have them put a better cap in it to see if that helps. Other than that I will replace as its a beast to begin with. Northern Lights Company ballast - out of business...

hey simba, will this ballast work with a CMH?

heres the link:

150w ballstwise digi

enigmatik.. no unfort not.. its a high freq hid ballast. we need ballast specifly for cmh.. like
http://advancedtechlighting.com/vs150.htm
but they dont have for sale at moment.(if u order it will get rejected) i guess only suppling Co's at moment..
/ballastwise isnt greatest but ok..

This thread has a lot of good info.I can't believe I didn't find it a week ago when I bought a 600w hps with a lumitek ballast.So if I get a new hydrofarm 400w hps ballast it will work the CMH bulb?

CMH bud pics! I am guessing around 600-700 grams from 800 watts of CMH. One things I noticed is that CMH produces more leaves than HPS. I think the buds are the same size, but it took me 13+ hours to trim all them damn leaves! HPS was alot less of a hassle to harvest. But hey, who can bitch about harvesting?

 

[Azeotrope]

Very Nice!

I hate to trim and I love to trim. I go round and around with myself on how much to take off while still standing and how much to leave for a hang and trim.

 

[simba]

micro<Awesome First Pic/harvest.. ya trimming is a love hate relationship.. LOL

without going to deep into this.. LOL
more leaves are better in a way.. more energy able to be absorbed.. (nugs dont really suck in the energy in comparison)
also impo we all still need to shorten veg time a bit..start=begin of flower
u start with a bush ur gonna end with one..
u start faster.. cause the plant matures faster to flower stage than under hps.. (
hps is like a slow battery charger, cmh is a bit faster..)
many have come back even saying there Known strain is ready for harvest a few days to 1 week earlier...
IMPHO it has to be the full spd.. being used at once.. rather than small nm ranges to do all photosynth work..

 

[gramsci.antonio]

CMH doesn't Throw Heat like MH or HPS especially MH
it just so happens the arc tube (from the HPS side of the lamp) Blocks and absorbs allot of that energy and instead of radiating it it holds it and releases almost all up.. * Ya cmh does still throw some heat but Nothing compared to Equal Wattage in MH or HPS..

Sorry man, what does this means?


I mean: The only physically legal way of emitting less heat is to be more efficent. If energy is absorbed sooner or later will be emitted again...

 

[simba]

Gramsci.. glad to see ya around again..(at least here)
ya cmh emits most of its heat on the vertical Axis And is less heat then hps or mh to plant area (AKA just flowing off the top of the bulb and easily being able to be sucked out or atleast by physics not go to the plants directly without cooling a bit first. whereas HPS or MH.. the plants are getting bombarded with Heat.. like when you walk in a walmart during winter you feel that heater thats hps and mh.. (u look up and see nothing but a black pipe)

to ur Q more to it..
in a air cooled hood especially but and even without but with just active cooling on the chamber.. ..
a 400 cmh will not heat the environment/ plants as hot as hps or mh (mh is hotter than hps and cmh to envrio and plants)

ill have to really get on some temp differences between hps, mh and cmh.. ill do so soon as its getting warmer day by day (i use 50 watt cmh currently for clones and im needing to keep the fans off otherwise its to cold for them)
(Going to change to 70 watt cmh cuase it has highest LPW even though im not big fan of LPW or L in HPS or MH case.. or even CMH as much as actuall SPD ranges..

Just chopped the Reeferman bonus mix girl tonight. Looks great, budz are hard, smells very sour!!!!










I'm guessing 3 1/2 to 5oz.

 

[haze12421]

Simba quick ? you please. I have a big cooltube i have bought and plan on using for my grow. Is a cooltube good to use with a CMH ? Thanx

 

[simba]

Haze, . you can use a cool tube.. although a simple air cooled hood would do Better IMPHO..(cause more reflector surface area..) but ur Golden..

 

[haze12421]

Ok so i have a order for a 400 watt lumitech and 400 watt blue spectrum, 400 watt MH bulbs.
I am going to refuse the order and lose out 20 dollars or so for shipping.
I will be purchasing a 400 watt mag. ballast that can support CHM.
Reason for swapping is worried about heat issues. I was thinking id keep the 400 watt blue spectrum. Use the CHM for vegging and if theres no heat issues with the blue spectrum, use that for flowering.
What do you guys think ?
Here is the link of ballast i have to choose from. Anyone have any idea witch of these is most quiet
Thank you for the help.

Also 77hydro.com said that they would exchange my cooltube for another reflector. Witch reflector do you think would be the best chm/hps
i was gonna pay a extra 50 dollars and get the super sun 2 6' air cooled.

Hey simba, any new words on the 600 and 1k CMH's? I've been out of the forums for a few months but i remember you saying awhile ago they were 6 months or a year out, any updates?

 

[smokadepep]

what brand cmh bulb are you guys using to get good foliage during veg? im looking to put a 400w cmh in my veg chamber, and i was looking at the philips mastercolor 4k that ive heard about, but it seems to put off little blue spectrum, compared to the green spectrum. chlorophyl activity is most active in the blue and red spectrums and is almost non existant in the green spectrum, would this be better then a regular metal halide, or maybe a mh conversion bulb for veg??

 

[messn'n'gommin']

It is the Philips Mastercolor Retrowhite 4K you mention. While it is true that chlorophyl A and B use little of the green/yellow spectrum, it is the carrotinoids that capture the photons in those particular wavelengths and make them "available" for the chlorophyl's to use. So, in essence, the greens and yellows are still utilized for photosynthesis.

I changed my mind after seeing "simba" advertise the bulbs on like 10 other websites with 10 different screen names...

And I seen him on many more
After looking and looking for some honest facts from someone who grew with the cmh and didnt just follow simbas advise and go out and buy them i gave up and went with the opinions of growers who have 1200 or more posts.. The only reason i was gonna get the cmh is for heat issues. But for 2 degrees less heat and and super leafy plants i'll pass..
Goin with the 400 watt blue spectrum hps and blue spectrum mh with the digital ballast.....

 

[Azeotrope]

Wow are you lost!!! Post count is just that a count of how many posts a person has not how much skill or education they have. Good luck with your piece of shit HPS bulbs.LOL Come back when you grow up!!!!

 

[simba]

haze in the nicest way i can say this..
I am Beyond Offended By your post..

I SIMBA DONT POST UNDER ANY OTHER NAME THAN SIMBA>> AND>> i do 98% my posting here and 1% at HG 4-2-0 and the other 1% has been on a lr forum.. (there is one site out there that simba is not me i forget the site)
ill admit i hit up every site and Read what is said on cmh but only post under the name SIMBA, etc (above)


im sorry your hosing yourself over a misimpression of a lamp and people backing it..

to your comments they require a Responce:

that first one i wont bother it Upsets me as its Outright-BS....any grower that uses cmh and Learns It will suceed.. (did u not see az pics and i thinki it was microwidows right above his)

heat issues allot cooler than 2 degrees like 5-10 if done right.. and 2 is a big diff to plants..

super leafy plants.. mean theres more area to absorbe the energy and turn it into goodies.. DUH>. (i have also said most of these Bushs have been veged to long.... cmh requires a bit shorter veg)

last point EYE HORTILUX is selling a wana be.. CMH.. (cause its mainly blue in its full spd cmh is more red)
there eye blue.. for $109 and in email from iawaski the cmh we recommend is admitted by them to doing better for One lamp use.
there eye blue has half the life and half the lumen maint to.. so its actually 3 times more expensive than CMH..
dont cut ur self short..
we have said over and over we dont care where u get ur cmh.. just get it..

i just relized i did have the handle Macgyver but that was my CB handle from 1990-1997ish.. cb got boring.. and internet was Alive then.. LOL>
