The Ideal spectrum.

I have not had anyone try to replicate nature regarding running high amounts of blue/uv and green for a few hours a day during flowering stages. I believe that changing the colour and smashing the plants with a high colour temperature say 5000kfor a few hours then reducing it down to around 2000k should be beneficial. As you are using the solstrips you could do this by cranking up the mono colours to 36 watts per board for a few hours. Green is missing from the monos to try this out though, green is responsible for stomatal control. Stoma means mouth, it should open the receptors up to absorb more light. If you want to do it I should have some spare pc greens from nichia around that I could get mounted to a board for you if you would like to try it out.

Anyone hanging around played with the royal blue COBs much? I was thinking they might be fun to experiment with. Big ole' blasts of blue light for a few hours a day at various points in the cycle.

You could try it, I suspect you would be better off doing this with 6500K cri70 or 80 though due to the extra green. My personal belief although not tested properly yet is that each colour has a role and different colours work together to increase results across the entire spectrum. Not sure if that makes sense but I will post it anyway.

Well I've already got 6 3000k QB288v.2s and 4 of the QB96v.2s between two fixtures in a 5x5. Each fixture has three channels with two in use. I'm waiting to bite the bullet on 2-4 blue COBs per fixture. I want to also add other channels for side lighting using more exotic spectra.

Will there be enough room to use the cobs with even coverage, as you are using quantum boards they are usually alot lower than a cob set up would be to spread out the coverage

Multichannel as in a Chilled board type?
Both spectrums look good, the reds seem to peak in right place.
Are they top of the range diodes ie Cree, Samsung , nichia?
I've seen some spectrums with a lot more blue than what you've shown
Fluence for instance.

I posted the writeup (the little info i have) on the Cutter/Solskin thread: the chips are cree j-series, cree xq and some other custom made phosphor coated reds:

Im getting 6 to try out, had them custom made.

Great thread guys!! Just curious though as to what sensors you guys use to test spectrum? I’d like to get one and get a reading on my cheap Frankenstein setup.

I use Amnesia Haze and Zkittlez ;)

Mote seriously: lighting passport comes to mind but i dont have any, they are quite expensive up to +1000$$
