Nice looking buds Gray!
Maybe I assumed you grow in larger containers. Would you mind breaking down what size containers your doing? Prefer? Etc.
Well, because of my room size and dimensions (45"x 53"), I decided when I got into growing that I wanted to stick with these 6 gallon square pots that I have. I could go to 10s, but I wouldn't be able to grow as many plants. The 6s nest in there perfectly in a 3x3 pattern - 9 of them. That's 54 gallons. Round pots waste space, and I'd have to go to four 15 gallon square pots to get as much total soil in there.
But I have a back wall that's underneath a stairway, so the ceiling is slanted and lower there, and I wondered what would happen if I ran small short plants back there in smaller pots. I did some measuring and sure enough, I can fit 8 smaller 3 gallon square pots into the space that 3 of the 6s take up. That's 24 gallons of soil instead of 18.
The question was whether it would work in a live soil. Doc has always said that the Kit will work best in 7 gallons or more per pot. But so far, the 3s are doing almost as well as the 6s. That lets me grow a LOT more variety.
So to answer your question, the small ones are 3 and the large ones are 6. The first couple runs with the small pots, I flipped too early and got less than an ounce from 3 gallons, and I noticed that the rootballs weren't completely filled out. So I gave the next batch more time and/or training and they're yielding 1.5 - 2 ounces now and filling the soil with roots. The 6s average 4+ ounces.
I've also done a long fluffy Haze in a 15 gallon bin and that went quite well. Halfway through bloom, I upcanned it from a 6 and it thrived. I got almost 6 ounces out of that one.
