hey oldmac,

I was hoping your uber-experienced butt would pay a visit. much obliged.

I'm glad you mentioned SOG, because that's exactly what I have in mind. And the CO2 as well. Running an HPS I have some significant heat issues, which disqualifies me from making good use of it, but with LED's I figure I can make up for some of the lack of light power by implementing CO2. And though I've never used it myself, I've heard it can increase yields by about 20%. If that number is realistic, that means I'll only have to provide 80% of the light I'm currently pumping with my HPS to get the same results. One step closer already, and the LED hasn't even turned on yet!

I'm happy to hear that the hybrid T5/LED puts the equivalent HID to shame. Another reason I want to switch to LED is that I can distribute the light much more evenly across the entire canopy than with a single light.

About your last point; thanks for clarifying for me from an authoritative source the truth that a procyon is not equivalent to a 400 W HID. To tell you the truth, I never believed that drum racketting anyway. My question is, is it reasonable to assume that 2 of these 90W lights would equal a single 400 W HID? If so, I am sold. Perhaps I'll throw in some T8's for good measure, or some T5's if I can find some.

In sum: the even light distribution, [potentially] lower energy consumption, and opportunity to utilize CO2 without the nuisance of running a continuous exhaust seems irrestable to a learning grower such as myself.
