Fabric or plastic pots

It can depend a bit on the substrate. I've never had a problem (in past) but i know others that had lots of water streaming out the sides. I think it was a living soil that just didn't have a good flow of water through it naturally, because like i said, in 1.5-2 years of using them, I never had this problem -- I used simple soilless promix/perlite (50/50) or 70/30 coco type substrates. shouldn't be an issue, but possible. the other thing is cleaning them. It's a fucking pita... if such things are no problem for you, easy to ignore. I didn't like soaking and scrubbing and washing to get the scale off and pull any roots out of the fabric. and often still had plenty of scale on the sides as i reused them. It was nice that it air-pruned the roots, but i don't overgrow my plants so becoming rootbound is not a concern of mine. Context matters. I liked them but the convenience and virutally no difference in outcome to the human eye made me prefer good quality nursery pots. Easy to clean. Last decades. YMMV technically better, but you can't see any difference.. if you do it's more likely inconsistency of method or genetic variety. I have the same vege times needed to reach my yield goal per plant as i always have -- whether in coco or sphagnum peat (with similar 50% air mixutre per pot volume) or whether in nursery pots or fabric bags... so little difference that it is imperceivable.
