Here is my take on it, having done almost everything in these past 10 years as a grower. From DWC/RDWC, coco, soil, top feed, bottom feed, run-to-waste, mapito, organic etc ... I think the only I've never done is NFT and aeroponics.
- Round plastic pots - tried and tested, they work
- Root pruning air-pots. Love the performance but hate using them. Difficult to water, loads of leaking through the openings. Hate the mess they make. It is impossible to give a good drench and typically that ends up making the grower underwater to avoid the mess
- Fabric - horrible when using coco/mapito and hydro nutes. Major salt build-up on the fabric that is near impossible to clean and burns roots. Also, easy to attract negative fungal activity, unless you have a rigid inter-crop cleaning/sterilisation procedure. Hard to give a good drench without water shooting out the sides just like air-pots. Never tried using organics though, may try it one day when doing outdoor, never indoors. Reason is, I freak out moving plants around/training. Feel like l disrupt the soil/root system too much as the fabric pot is not rigid
- Squared pots - What I am using currently and liking the best. I can bring plant closer together (as opposed to round pots) and easier to train them indoors. The root bound argument doesn't convince me at all. I feel no decline in performance compared to round pots.
Depends on your setup I would say. I am definitely partial to fabric pots for obvious reasons, just that indoors managing a tight spot needing to move plants around and training them, I'm not a huge fan. However, there are lots of dudes and dudettes out there who are happy training plants with fabric pots. I've been known to try it too, but snapped some branches when attempting to move plants around.
