Ceramic Metal Halide (CMH)

Azeotrope

le Marcel - Something makes me think that your thumbs are deep green!!!! Nice job. I will throw up some pics tonight to illustrate (as you so skillfully did) that big dense buds are the norm with these bulbs.

Wish me luck this week it is going to be over 90degF here. 800w CMH in 6square feet!! I made it through last year but, man talk about pushing it. Try that with 800w of HPS. :rasta:
 
Yay, ordered my 70w CMH and ballast from ALT last night for my mother/clone chamber.

Im gonna be doing a DrBudGreenGenes style SOG in my flowering chamber. 6 zones, harvest every days 10 days 24 clones at max capacity in a 2'X1.5'x3' space.

I wanna get the 250w CMH but im worried about heat since im gonna be using an open air reflector. Do you think I can get away w/ a 250? Or should i go w the 150? Using a S&P TD100 inline fan for cooling (http://www.hvacquick.com/spfnconfig.php?fm=td&PHPSESSID=m90ms6m1lcv48pknkdeb1kpvo5).

Ya Nocal, They do jump colors while warming up.. thats the salts/metals mixing ya i like it..

Silica any brand as long as its potassium silicate..
it Provides for Cell divison,
Heat Drought and other toloronce go up..
also creats Glass-Type Inner Stucture on Cell walls on the stems holding them up allot better.. making them stand to atention even with weight..

Messs, ya go with 12G Grounded Heavy duty extension cord or Romex 12/2+ground
what it comes down to is the resistance from the ballast core/ignitor to bulb..
(it has to be less then x.. and if you lengthen coper wire it gets there fast)
we have delt with 35 watt HID Xenon and when extending the ignitor from ballast it needed to be Very closely watched with Ohm meter to stay in regulation..

Green looking Good. Good run..

Lem..im coming over LOL/ JK
Looking Reall Good.. you def got green thumb going on..

Smoke trich..
ya a 250 is easy to cool what was the cab dimensions again.?
if you have a small fan blowing up into the reflector and then have your intakes at the bottom and exhaust at top with Constant flow it should be good..



Ya, AZ goodLuckk but ya dont need it..
something we have thought about is a Dimmer Setup based on temp and when/if goes over 90F Room temp it would Dim lamp to 75% obv simple ya think people would want it.. i have the plans already..(schem with thermal and relay for the extra cap)


That 680 CMH is not Open Fixture Rated and has a LIFE issue.. Thats why adv tech dont carry it.. (failures) but they are working on it.. from my understanding.. i expect philips firts but either way.. adv will have first useable unit..
i have not said anything about GSY for ever because i dont want to get the hype up..
again i have seen 600 and 1kw cmh and NOT FOR US>>
You will be BLIND Well sever snow blindness. (they are for HIGHBay or even Some high LOw bay)
also gs best cmh is 122lpw.@360watt.. its 680-1000 Drop LPW to 100
philips to announce 144lpw cmh
so you loose because inv sqr law and then lpw.. (effeicancy(
it comes back to more lil sources better than one big one..
adv tech has the gs cmh pdfs.. showing all data..
(adv hopes gs yuasa lighting will have open fixture and lamps we want soon)
guys really forget about using cmh more than 400 watts..
we really have to rethink lighting.. needs. (think the shadows your 1 600 or 1kw has.. even if you go 2 600s.. vs 4 400s (ya at that point ud be using more watts but the area would increase and actually provide more..
guys.. i have people coming from 1kw and 600s saying how after they harvested they still cant believe that they dont need to use space heaters any more (600's and 1kwrs) to achive Same to better results (more of better the same are the ones still learning it..)and we are talking 3KW+ Opss

i know few peeps even with 3-6, 50-100 watt CMH par lamps using 3-6 50-100 watt vs using 400 HPS and they have increased there grow size. because of the better/uniform coverage.
Ya higher init cost (3-4 bulbs and ballasts) no reflectors though help allot..
and the cooling of them is so much better..
many of the micro/mini growers go down 20 watts from hps.. (IE 100 watt hps now using 70cmh.. and even a 50hps user now using 25 watt CMH with same results.. (shows the extra hps energy is Outright wasted IE my posts about hps wastes ourtright 20-30% and then some..

The following pics are some of a "bonus mix" that one of reefermans guys sent me a few years back. I feel stupid that the leaves show so much nute burn, but I have found some nutes that I can get locally that are working well in coco. I have yet to dial in the dosage on the 3-20-17 bloom booster.LOL












The next is a JohnnyBlaze Girl




And some SweetBlue(m) X JohnnyBlaze(f) that are in 90%coco/10%EWC and 12/12 from seed.
:joint:

Let me try that again:

One more of the JohnnyBlaze girl and then one of the SweetBlueXJohnnyBlaze.





Peace
 
Thanks for the input Simba, decided to go w/ the 250w CMH. Gonna rig a pc fan to the other end of the reflector, and have it on during the light session. Man I wish I'd ordered earlier in the week, cuz I won't be getting my stuff till mid next week. :(

Os -

I don't think my 5yr old 3megapixl does the trich coverage much justice. Those colas are hard and dense and have 3-4wks to go. I will update closer to their end and see if I can get some better pics at the end. However, I respect your thoughts and hope that your growing is everything you desire. Peace and best regards.

What would you suggest for a small box to run several plants?

The dimensions of my box are 19inches wide x 22 inches long x 29 inches high.

Looking for something that will work good without HUGE ventilation problems..and i think i'll need a small carbon scrubber as well for it..(suggestions are welcome here as well)..

Thanks everybody.

Harvested one of my plants. The buds were too heavy for it to hold up anymore and I wanted to try some early harvest bud anyway. It was maybe 50/50 cloudy/clear.













And here is the larger of the two. I'm going to keep it until it is 50/50 cloud/amber. It's also starting to drop its colas.

OK..been thinking. I would really like to put the 150W CMH inside my 19x22x29 box. Do you think i'll be able to do this and keep it cool?

If so, wheres the best place to get the whole 150cmh setup?

alright...so i think i wanna get the 150CMH...You say cooling is not going to be a problem...what fan (CFM) should I look at and whats small and quite? Also, For this ballast kit? Can I get that from Advanced tech as well? or would i be better off gettting a other 150HPS ballast Honestly this whole ballast kit thing scares me a bit. Whats that about the ignitor and the fuse the customer will have to supply w/ advanced tech?

IDK..maybe somebody can explain the ballast info a bit better to me..

Heya, B10
ya fans i dont recommend brands etc.. to many.. i honestly lately i been going for the cheapest (like pulls from PCs)

its a pulse start MH ballast you need..for cmh
only the 250,400 retro whites are HPS ballast-able

ya with a ballast kit you will need a fuse.. No ballast kit comes with one..
most ballast boxs u buy dont have fuses it will have a fuse only If it says UL LISTED on the outside of the ballast box (brand name expensive units that ur only paying for that fuse and name)

Ignitor.. its a ballast kits meaning it comes with everything needed on the ballast side.
you will need a socket (medium pulse rated) which u can buy from adv tech.. $3.00 with ballast purchase.

also when u buy ballast and bulb from adv tech you pay only shipping for one box.. Saving $$$

wiring ballasts are super easy..
I have pics on my cams mem stick but i cant find the dam thing...Ill get pics up Tonight Promise
 
U

UBER21

Simba need some help wiring the ballast if u plz.....connected all the wires as in the diagram but no juice to the bulb.....the ballast is working as its getting warm....but the bulb doesn't ignite....what's weird is when I unplug it a shot of light hits the bulb for a quick sec......?
