The last time I actually did the math, I was still in the 4x4 flower room. I was averaging a qp every 2 weeks, with that coming from a 1x4' space, which means I'd have gotten a pound if I pulled all at once, for 450ish grams out of a 600 watter. That puts me at .75 grams per watt, not exactly stellar but not bad. Over the next month or so, I think i can blow that number out of the water. My system has been in a perpetual state of flux for the last month or so, but things are looking good for the near future. The older plants are a little stunted from all the changes over their lifetimes, but the younger generations are looking like little bud factories. Here's a look at a JtR, followed by a Sour Grape.
As far as the CMH goes, yeah, I really am seeing close to an inch a day some days, it's ridiculous. I was running a 250 watt HPS before, I just switched bulbs. I veg little plants in shelves with CFLs, but I also have my 3x3 veg box for for the plants in buckets. You'd think I'd just put em all in the same room, but it's easier space-wise to have the box and the shelves seperate. But yeah, not only faster growth but lusher as well, the fan leaves are huge compared to before, the stems are thicker and juicier. Even the roots seem to grow faster.
That pic was about 10 days after transplanting 2 10" topped plants into the bucket. In that time, the 2 little plants got big enough to train around the rim and developed those massive leaves. I'm psyched. That's my first bucket of Mountain Bastard, my bagseed creation. Oh yeah, and while Bill Nye is the man, I'm gonna have to go with Mr. Wizard, cuz I'm old.
