Here's what my tent looks like atm.... I start the small pots when the big plants are 30 days or so from being chopped. Then they get up a little size the big ones are chopped and the small ones tower over the sprouts but do not block the light. By the time the sprouts get large enough to need the entire tent the small pots are chopped.
I see folks making the "mini dwc" in the Solo cups it's really cool and I hope it works. But the key for me in small pots of growing is treating it as a "passive hydro" system..... using a soiless medium (coco or peat) then watering 2 or 3 times daily with run off.... that's a passive hydro system and the root mass doesn't have to be as large to do the same job... if you notice the guys who run passive hydro with drip feeds pull massive weights from 1 gallon pots
The plant on the left is auto purple amnesia the one on the right is smaller but in a 1 quart pot (more medium) but it's a spur blur from mephisto it's a smaller strain and not eligible for Mr. Marz comp here
