Please discuss/argue current wisdom about deep red.
in veg and flower Ive seen better growth adding 660 than not
I don't think there is any question as to the benefits of having some 660 present. As to the percentage of 660 in terms of the overall flux in this range I would point towards this side by side where the percentage of 660nm is approximately 15% of the overall flux output. Check the gallery images and the notes below the images which show fruit counts,densities, size comparisons where 660nm diodes are used against a phosphor blend that peaks at 640nm and 1/2 peaks at 650nm.

hey , do you know what pic # these are at? I'm not seeing any of it pop up for me..
another question, is that light in the link, the 420 watt model?
Hey Chaz, but isn't the indagro bulb like 5600? A bit too cool for good fruiting. Here's a quote I go by, and am in the process of proving it now
