I'm only just setting the tray up right now so I don't have an answer for you. But I've built 2 smaller/cheaper trays for others that are both in use for awhile.

One is 2'x2' and is lit by 2-Procyon 100s, plus 2-T5HO 2' (48w total) and 1-25w red glass incandescent. They use 2-T5s (with 6500K bulbs) only for rooting the cuttings (24/0) for abt 10-14 days, then the Procyons are added for another week or so of veg (all at 24/0). Switched to 12/12 and after the first 2 weeks of flower the T5s are switched over to 2700K tubes. The total is abt 275 watts. This tray has an average of 1.1-1.2 grams/watt. BTW this system is not using any CO2 supplement, so it could go a little more with it.

Hope this helps with your curiosity.
