So it sounds like you use a lot of these as supplemental lighting? Sounds like you are really dialing in on very specific spectrums for your plants. Are you growing the same genetics?I'm very limited in heights and using only CRI90 is to much far-red for my taste. I would use ⅓ CRI90 only in flowering mode and on a secondary driver simply to enhance the red part of the spectrum.
