HPS, MH, Floros, Phillips Cermamic Metal Halide has 'em all beat.

Well I have to say that after much research and many months of pondering over Plasma and buying LED's that I am absolutely blown away by the CMH lamps. There is nothing anywhere else that can touch them. Phillips have made these lights SPECIFICALLY for growing but can't say that now can they ????????. Get on the wagon and rejoice in the fact that we now have the next stage in the evolution of grow lights. If you don't believe me. Try them, go on, I dare ya .

Many Thanks.

for all ya disbelievers there is plenty of grows on icmag that use CMH and have fantastic results. the proof is in the pudding now go find the pudding. from my research ive concluded that...

-CMH gives a very slight less yield compared to HPS

-CMH puts out slightly less heat, but the big factor is that the way a CMH bulb is designed the heat tends to flow up through the top of the bulb more so than an HPS, therefore less heat is pushed downwards towards your plants.

-CMH gives plants full spec at high intensity allowing the plant to use light where its needed when its needed instead of being forced to work with what its got (HPS). because of this the plant looks and smokes more like outdoor weed, which i think is always a better smoke. the plant is probably more potent although i have not seen numbers for that statement. because of full SPD the plant is more floral smelling. MMMMM

-buds are leafier because of added blue light

this is all based off observations that ive made from following CMH grows, for the past year or so.

this is not to say HPS does not have its place in growing. the yellow-orange spike HPS has is great for flowering plants, but from what ive seen if i had to choose one bulb CMH wins hands down.

the best plants ive seen indoors were 1k HPS and 400w CMH under the same hood. WOW

Think I'm going to have to give these a try . Regular 400W pulse start MH throw off too much heat Good thing there are some spare HPS ballasts laying around here somewhere....

ok im new to this but i have a 400w ballast (not digital) runs mh hps and hg bulbs...it says luminaire fittings idk if that will help, but can i run cmh on my setup??

If it can run a HPS, then you should be good. Also, just ordered one of these ceramic pieces of goodness to try out...

THATONEDUDE,

Awesome pix man!! Love it! Can you please help me out and give me the top 2 ways you got you girls to get the fat and round? I keep getting tall skinny plants...

sweet...let me kno how that bulb does for ya...and what did u pay for it??? i can get a 400w for 70 and i can only order it online...no hydroponic stores carry them around here yet

Yeah got it ordered with shipping for 55$. Won't be here till around the 22nd? though due to a back order. I'll for sure post how it does. I've worked on a whole shit pot of HID lights, including LED, but have absolutely zero experience with CERAMIC MH. Hoping for good results..

Just starting on making my new micro cab and so far I thought of going 150w cmh+70w hps but the specter from 250w retro white is just awesome =O. You guys think I should forget the normal cmh+hps and go for 250w retro white?

Where do you buy these bulbs in EU?

Thanks!

this is the lamp i use in my grow - i actually use the 575 watt, but this 250 has the same benefits

it has a quartz shield on it so you don't harm your eyes from the u.v.
also, check the spectrum: just like the sun, but in a modern lamp -
you will have to build your own ballast because this is for industry, and you
may need a remote ignitor if you decide to go for it
