You widen the margin for error in anything smaller than 10-gallon pots in organic gardening like your no-till system but you don't veg out very long so smaller pots should work for you. Your last few grows have looked good to harvestThat's all it is - bio-mimicry. Trying to bring the outdoors in.
I'm still a stubborn bastard though because they tell me that 5g pots are too small. Fuck 'em, it's twice as big as what I did grow in, I'll make that shit work!
