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.
oldmac Reviewed by oldmac on . Procyon vs UFO LED Hello and hi, Does any kind gardener have the scoop on this here comparison? What I'd like to know is how these much more affordable 90W UFO's compare with the much more expensive Procyon 100's. While I do expect the Procyon's to outperform their lesser competitor, perhaps this 'lesser' is not so less? I don't expect anyone to give an answer who has done a scientific, side by side experiment in a NASA laboratory, but any advice from some UFO experienced growers would be thirstily Rating: 5
