Supplemental UV for LED grows

Those UV bulbs are not designed for 12 hours of continuous use. You do short incremental blasts. 15 min on and 2 hours off during the lights on cycle.
 
Update... I purchased an evaluation unit for my grow from California Lightworks, a Solar Storm 1100. It came with two UVB fixtures that hang off the side of the 1100. Oddly enough there was no documentation at all either in the manuals or on their site (that I could find) that lists amount of time and when they should be used. If I'm reading things correctly here and other places it sounds like I should leave them off until last few weeks of flower, and then only for very short bursts on a timer every couple of hours. That sound right?
 
I don't know if this will help you are not, but I use a 10k finishing lamp with uvb,in it,from GrowersChoice,in my 315cmh, for the last
week or two, growing autos, and I keep it on 24-7, my plants seem to like it just fine, doing it that way. GoodLuck

Serapium
 
D.A.A.S.69 thanks. I had looked at those finishing lamps and intended to run a couple once I get to that stage. I'll have about 14 CMH going total from three different brands, all running alongside some LED's from various manufacturers and a few HID as control groups for comparison. What is your overall impression of the effect of the finishing lamp compared to the standard Phillips CMH lamp? Have you finished with both and been able to do a comparison between the results?
 
Serapium Man of man, you got some plants growing for sure,
I only grow a couple of plants at a time, 3-4,but I usually grow 2 of the same kind, most of the time, and you are right the Phillips lamps are the best ,imo.
But having grown the same plants a few times with just the Phillips lamp,which does great, I can easily see the difference in the stickyness, resin with the 10k finishing lamp, even with my old eyes.lol,
They are kinda expensive though, but you don't have to run them long either.Which helps.
Your SolarStorm, should be a great light, to,good luck with it.
