UV lights

[sato108]

Good morning folks,

I had a question regarding UV lighting. I was looking at adding a few of RapidLEDs
SEMILEDS ULTRA VIOLET UVA LED (390-400NM) to my current light setup.

I'm lighting a 4x4 area. Using 8 CXM-22 @~75w each (the light frame is 3x3). Was wondering how many of the diodes I would need and if anyone has used them? Also can I run these 12hrs without hurting my plants? Any thoughts, suggestions, are greatly appreciated. Thanks!

I use UVA 385nm for improved taste and run them for 12 hours. Low wattage I run 8-3w UVA in a 2x4. works for me.

Vegas, where did you get your diodes?

I decided on the luxeon deep reds and UVA from Steve LEDs. My question is, they are both rated as 3w chips. But the Fv on the deep reds @ 700ma is 2.2 and 4.6 on the UVAs. Can I still run these on the same driver or should I separate them? Don't have a problem separating them, just trying to figure it out for wiring purposes. Thanks again for any info!

what attempts have you made to ensure

you ain't gonna get eye cancer within the next 1-2 years

with the use of these diodes?

please explain

Aside from not staring directly at the light? I'm joking. Lol.

As with anything we do, especially in DIY, there's always a risk. I did look into it. I do wear glasses that are photochromatic and block UV light. As far as the skin, I try not to work under the lights. I'm not in a tent so I have space to pull the ladies out and work on them. I'm also figuring that at 3w the risk is much lower than tanning for example. At least according to what I've read. Everything else aside from that, is a crap shoot.

i don't know about the diodes, but some agromax t5's will kill you plants if you run them all night every night.

i run for 15 mins every 4 hrs in the middle of the light cycle. have 2-3 feet above the canopy too. so in the case of this particular T5, a little goes a long way.

why not just run Arcadia d3 + 12% entire cycle....

because i bought two agromax's

I'd like to know how I can tell if the UV is too much for the plant. Are the symptoms similar to light stress, e.g. bleaching? What are the first signs?

Plants start to wither and wrinkle on top

Left my 26 watt on for 3 hours once. The branches it was pointed at, had leaves that were damn near black, and curled upward on the ends. Leaves were purple before burn, prolly what made em black.
