I'll try getting the 90W UFO light with the mixture of the blues using the absorbtion peaks you've shown me in those charts. Let's see how the plants like it with just blues for veg.

Excellent! I'm curious about the blue peaks but 430 nm. leds appear to be a rare beast. At least they were last year.
And I love a well thought out experiment.

For the flowering light I'm going to load up on the 660's per your advice. Though, with me using the 1W LED's as opposed to the 15W ones that you use is that ratio still alright?

Wish I knew that as a certainty.
Since the 15W emitters are actually 4. 5 Watt dies on a single substrate, it would seem that the ratio holds.

Or, should I use more red and less blue since they are weaker lights? More like an 8:1 ratio because of their weakness? (they bow down and cry in the presence of your lights!)

Pshaw! "Many hands make light work".
Just keep yours closer to the canopy.
And if you cut it to 8:1 you may have more stretch than you want.

Your thoughts?
Oh, no, brah!
You nevah wanna say dat to an ADD.:tin foil hat:

Betta you re-phrase dat or we be here all night.

I only half kiddin' 'bout dat.
My brain is "on the loose wig alla time".:jointsmile:

But, thanks for asking.
