Hey, sorry guys - didn't think anyone was still lookin' at this thread.
amstercal, I wish I'd been that efficient, lolz! For that run I had 10 sites, 85ozzies, and 2400W, which works out to almost exactly 1 g/W. Good, but not mind-blowing, y'know? A new thread hasn't been made 'cause I haven't done a summer run at my location yet, and there have been some unexpected challenges.
Now I'm running a 9-unit grid with three different strains. I'll flip 'em in the next day or two, but obviously I can't expect anything like my last success, as I doubt I'll be able to optimize conditions for all three strains. It's an experiment! Huzzah for science! ;)
