Ceramic Metal Halide (CMH)

Also... First grow EVER... Simba's info convinced me enough to use 400w CMHs in both Veg and Flower, and supplement with a HPS in flower also.

Progress is vigorous!

You are doing the right thing.
BTW....flip em now! That spot is going to be overrun if they are still in veg.

ya flip them babies now!!! if you can get some canna organic bloom stimulator to force flower onset as fast as possible..
 
Hoosier and Simba... no worries. That is only the veg room. My flower room has 2.5 times the depth, and 1.5 times the head room.

Thanks for the warning though. Also, my flower room has a vertical Philips Retro-White and a vertical Growbright HPS.

What do you guys think... CMH higher than the HPS or vice-versa?

CTSV showing yet again how it's done!

GE, th4e way I sees it...the higher the sun is in the sky, the higher concentration of blue light. When the earth's axis is tilted in the fall, the sun is lower in the horizon and the more red of the spectrum is prevalent. This reasoning is why I put the CMH on top, and the HPS on the bottom.

Thanks man. I am actually about to switch my configuration up. I am currently running 1600w in my flower room, and 400 on a mover in my veg lab. The 1600 are hung statically from above. I used to run 1200 close together on a mover, and got better results, so I am going back to that method. I am going to take the extra 400 and add it to my Veg Lab and run 800 watts on a mover.

I have also decided to experiment with the 8 site water farm. I am going to run two in my flower room, and keep another 8 site in Veg, and switch buckets out in a staggered sequence.

Should work really well. Ill post some pics of the new configuration when I finish it.

I don't really understand what your deal is?

In another thread you said "HPS rocks...CMH blows", Now you say:

show us those huge CMH nugs
Do you have something against CMH? A type of light bulb???

CMH produces top notch resin production. Hence, all the macros. In case you don't know the little crystals are what you want. I know have grown all different ways. Where as you have pictures of....nothing...

I grow 100% organic, which means I am not really concerned with yield per plant. If I was a commercial grower, I would go Hydro or Areoponic (like I used to). However, the best weed is produced under CMH in organic soil. I have come to this conclusion from years of experience with MH, HPS, CMH.

No reason for you to act like a smart ass.

Let's see some of your HUGE colas...

Then when you get a bunch of crystals together, you can make this...

I would like to set-up a 250 watt cmh in a 2'x2' grow lab. What is the best ballast/lamp/reflector kit currently available for this..?

Hey guys


Im thinking about putting together a dual bulb hood for my 5x5 tent


I want to do 1000w hybrid hps/mh + 400w cmh

both inside a growzilla hood


any recommendations?

No, the 150 requires a pulse start metal halide ballast. Just the 250, and 400 will run on a magnetic HPS ballast.

Is it time for a CMH social group? One for true believers?

CSTV or Simba? or anyone; of several others?...the ball is in your court....:headbange

Build it...they will come

Sounds like a great idea!

I don't know how to do that though...

Just to update things. I was running 1600w of CMH hung statically. I have now changed everything. I dropped down to 1200w and put them right next to each other on a mover. I am using a two CMHs on each side of a HPS. I then took the other extra 400 and put it in my Veg Lab for total of 800w of CMH!

I've decided to document a plant with 800CMH and 400HPS, and then document a plant using 1200w CMH. Same strain, nute regimine, wattage, just the 400w HPS is a variable. If there is a difference, then it will show.

I know CMH is better, but I want to document the difference between a mixed CMH/HPS spectrum and a 100% CMH. Should settle everything once and for all. I'll keep you posted!
