I order Quantum board but decided to go without the IR and UV diodes. I've read they burn out and I also think the UV was token. I've worked in UV photography before and know a little about UV but unable to find much info on how much UV is required to get the extra results.
I was thinking that I could look at some UV and IR strip lighting but are there any other options?
I've got an old UV led strip that I can do a test with in one tent.
My setup will be 2 x 8 x 4 tents with 2 x 480 per tent, the lights are from Yuanhui on Alibaba.
One friend has recommended putting a HMS in each tent too....
Interesting to know what combines well with these these new quantum boards :-)
Bit of research needed @Tommy_Green
UV a & UV b different in terms of effects and largely the one needed is not supported by light comp mies ( think UVb is needed but most lights dit UVAa?!?)
Same goes for other end of spectrum red/far reds (=Emerson effect?!)
So will come down to what you want to achieve with the additional lights.
Oh how I have missed this thread.... Not lol FWIW. Blue (~450–520 nm) and UV (< 400 nm) Light Blue and UV-A light triggers cryptochrome (320–500 nm) and phototropin (phot1 and pho2; 320–500 nm) function (Jones, 2018). These two photoreceptors regulate various physiological and developmental...
And @MIMedGrower said let there be red and far red info. An there was red and far red info 😁 Red (~625–700 nm) and Far-Red (> 700 nm) Light Red light impacts photomorphogenesis, leaf nutrient content, and stem growth. It is essential for chlorophyll synthesis and for straightening the epicotyl...

I'm in the same boat kinda, got some qb288's (with lm301h chips only). And would like to add some spectrum to my grow.
What do you think of the following products:
I use UV as a supplemental by hanging a 2' T5 High Output Fluorescent on either side of my main grow light - 24" hang height (not attached to it, just on the sides of it) . Each T5 is angled at 30° toward the center of plants at height of 12" from canopy. I have two different bulbs that are used in rotation : Eye Hortilux Full Spectrum + UV and Agromax Pure UV. The FS+ UV is used starting in veg (stay on when lights on) and Pure UV switched out intermittently only starting last two weeks (starting from only 5 minutes every hour for 4 hours in middle of lights on and increase by 1 minute per day up to max 15 min/ hour and no more than that as Pure UV is super strong.
Agromax Pure UV - 280nm and above Hortilux FS+UV - 300nm and above
Careful when using Pure UV as the spectrum goes down to more energetic range at 280 along with having more intensity at the UVB range over the FS+UV.
Tanning lights work great for adding uvb. 2 hours a day in the middle of the day. I like the tanning lights with built in reflectors. Tanning lights have a 4‘ range. All you need to do is trick half the plant into thinking it is being sun burnt for the whole plant to respond and create more trichomes. The way I understand this is, Trichomes are light refractors like a prism and protect the buds (seed sites) from damage from the suns rays. THC is then secreted through a membrane in the bottom of the trichome and up into the ball of the trichome to help the light refraction process.
