Procyon vs UFO LED

[macnasty]

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.

Your figures are good for the UFOs, 1 per that size tube sounds reasonable. I asume you are talking about using T5- 2' tubes. They are 24watts each using T5 HO. You can get single strip fixtures ready to run and use two each or a 2 light fixture, or even just buy end caps and a ballast and make your own. Now if it was me, I'd probably use a IceCap ballast (you can run four bulbs from it) and drive those 2 footers to 40watts each. Slightly more expensive that way tho. I would use red spectrum, 2700K if you can get them. Google "access discounts" sorry I don't have the link, but they have had T5s with that K, or next choice is the more common 3000K. BTW even tho they are warm color they have plenty of blue in them and will get you more orange and red, maybe some more energy above 630nm. Hope this helps.

I saw your grow log, and I'm interested in how well those panels do. That height recommendation seems high to me. That's 4.5' to 6' above the plants, I am not sure you are going to get enough light energy to the plants from so far away. I realize that will give a very large footprint but at what light level?
Do you know how many diodes are in it and how many watts each they are?

You can post your answer on your grow log thread, and I'll catch up with you there.
