I find it interesting that they are using 450. According to my charts that's about in the middle of the death zone for chlorophyll absorption or activity for vegging. 440 and 465 are the veg peaks on my graphs, and there is a drastic dip between the 2. Assuming my charts are correct for a second, growth should almost double if the other 2 were used in place of the 450 and produced about the same brightness total. Assuming SnS's plants are abnormally bushy, why? I guess either (1) my charts are wrong for weed, or (2)an array with proper wavelengths would do even better than the procyons, at least in veg., or (3)it's because all LED's emit in a spectrum believe it or not, and the plants are still getting some small amount of 440 and 465. Just bouncing ideas here, hope y'all don't mind.
