Absorption of the different wavelengths mediates phytochrome activity (which is associated with vertical growth, flowering, fruiting and a bunch of other things), but not photosynthesis.

On the topic of equipment, little of reefing equipment is novel. For example, plant growers were using halides and T5s long before we were.
Photosynthetically available radiation.

Buuut anyways, yes, interesting note about the phytochrome mediation. That makes more sense.
