Lighting Custom spectrum / UV advice?

[thetreeman]

Looking at an apollo 8 with the following LED's / panel.

Is 8 UV's too much for a single light?

15 3w LEDs total / panel

UV: 380-410nm 1
IR: 730-850nm 1
red： 620-630nm 2, 7 660nm
blue： 460-470nm 2, 1 430nm
White： 6500 1

Any changes you would suggest? This will be used for a variety of plant types, primarily leafy greens.... :check:

Hello Treeman, Its all about what type of uv you are talking about. you dont see Uv-C in lights but that mostly kills germs cells, uv-b is whats called "dangerous" uv but it works really well with canna plants its cause them to produce more resin glans as a self defense kind of like plant "sun-block" but with that too much can also cause problems. you really only see "high end" leds use Uv-b and it can get pricey i think solor storm leds use Uv-b light and i only see good grows coming from those lights, which comes down to Uv-c its the weakest of the three it is what you find in black lights but its promotes flowering. you can google the different types of uv and get a more general idea of how each effect plants.

200-280 nm: Germicidal UV (UV-C)
280-315 nm: Dangerous UV (UV-B)
315-400 nm: Black Light UV (UV-A)

here is a thread i started to share some of the reasearch i found out about my blackstar.

Ok, so Ive learned a few things. Would you not include the UV LED's at all if they are in the blacklight spectrum instead of UV-b spectrum then? Also, if this light is intended for full life of plants, would it be better to not include the IR also?

Another thing Im considering is actually getting 2 apollo 8s for a 4' x 4' enclosure. I could get one with no UV or IR and add an additional red and blue diode for veg and then add the one with UV and IR for flowering, say 30-40 days into growth....
