2019年5月2日 · Just doing Thread on 315w CMH lighting, for those interested in it, or finding out about it. Firstly.... CMH- CERAMIC METAL HALIDE , or LEC- LIGHT EMITTING CERAMIC. It looks an old school MH or HPS digital ballast and bulb set up..... But its a WHOLE different ball park! I use a Lucius Recom 315w CMH Broad reflector kit.

2025年3月4日 · I think it is good to wear sunglasses as CMH light produces high light output which can cause damage to eyes. So, I recommend to wear polarized or mirrored glasses to lessen light effect directly into eyes. You can take useful …

2020年11月8日 · For the CMH growers I thought I would share my experience from a distance from light perspective. I have a 4x4' tent and run 2 x 315CMH with Phillips globes. The reason for 2 CMH in the 4x4' tent, is I don't believe you get the strength of light with one and is better suited to a 3x3' grow. I've completed 5 grows now, 4 period and 1 auto.

2019年1月25日 · I've got 2x 6'x4' cupboards, I've just put 1 x HiPar 630W CMH in one on a light mover and 2 x HiPar 315's in the other, it will be interesting to see the results for comparison. Initially I tried 1 x 315 on a light mover in one cupboard and I was so impressed i bought a 630 to throw in there as well and turned the mover off.

2020年2月6日 · Ive been happy with my Sun System 315w CMH with internal Phillips ballast...for my first grow...drying now. Yield is on me for non light related issues. I needed some heat due to ambient 65F basement temp and full corner to corner light coverage for my 3x3x6.5 customr grow cabinet. Temp ranges 65 to 81.

2017年2月9日 · New to :420:, hello all, happy farming.. I have a light spacing question. I have a 1000 watt air cooled in between 2 CMH 315s. They are within a few inches of one another, I am trying to deliver a heavy mixed spectrum to all plants …

4 天之前 · If you want a light to take you from veg to flower look into a 315 cmh I have used one in my 3x3 with good results.I would recommend getting a Phillips bulb for the cmh as they are the best and get one that is 3100 k as that is the right spectrum of light to take you from veg to flower. Another option is Quantum boards which you can get from hlg.

2020年1月2日 · The most likely time to have condensation in your grow space is when the light first comes on, as that's usually when the temperature is the lowest, and humidity the highest. The water carrying capacity of air doubles with each 10°C / 18°F rise in temperature. With a CMH the humidity will drop quickly.
