Heres my first 315 cmh grow. This light is all i could hope for. 2 mainlined super skunk sensi. 4 week veg. Second week in flower. The one super thing about cmh for me is the tricomes. Every leaf on the plants is busting with em. I will post again in a week when the frost is comin on. That little room is a steady 78 degrees and 40 percent humidity. They get organic plancton twice a month and phd water inbetween. I finally got the watering down. Oh yea its plain old potting promix nothing else. Hmmmm... oh yea Happy New Year. Man i'm baked. Lol.

No they made for open hoods. If they’re behind said glass the uv they produce would be blocked thus defeating the purpose of them.

They definitely aren't made for open hoods, the double jacketed bulbs can be used in open hoods because in case of bulb failure the explosion is contained within the extra layer of glass. The second layer also blocks UV which Philips most likely considers harmful to humans (since it is), since the bulbs weren't originally made for growing cannabis.

If you intend to be working near the lights I'd definitely use the double jacketed bulbs, even though I agree that the UV is good for potency. Safety first!

Its the 3100 that came with it. Its a fusion bright. From growlights canada. From what i have seen you will ne good with the nanolux. Ushio makes a great bulb bjt for 110 bucks. I dont think my skunks care. Lol. Cheers man. I had to raise i it today. Go figure. My old led sucked. Lol. Now i got light to spare and the tricomes........ be sure to tell me how you do.

Hello happy holidays everyone.
Just seeking advice on new lights.
I was just curious on your thoughts about a 315 CMH light.
I grow autos and maybe a 2 photos at a time, I grow just for a hobby.
Are these lights worth it?
