ok. here are my current 'calculations' based on what i've read so far: IF a procyon is equivalent to a 250w HPS, then I'm going to assume a UFO equals a 200w HPS. I will dedicate a single UFO per 2'x1.5' DWC tub in flowering, supplementing with roughly 2x40w of T5 flourescents per tub. This should give the appearance of a 280w HPS per tub, at 6-8" from the top of the canopy.

How do these figures sound?

also, should I be supplementing with red spectrum T5's, or blue, or a mix? The UFO's have only 630nm and 460nm LED's @ 8 to 1, respectively.
