air pot, smart pot, cool ring.........they all have the same function
by design smart pot is better, no assembly, they are sturdy for it being a fabric, light weight, easier to have a large quantity shipped, and the least expensive.
OK i know I'm new around here, and I'm with ya that sounds to be the case from what I've been reading in this thread here, no personal experience true. however lets revisit a thought or two for a moment if we may?
one downside to air-pot and the fabric one's etc, is that they leak. that last bit there addresses that. and as for how to keep the fabric together, i would think that staples should be fine. no worries on moving/rotating the plant as its in the pot. pot in picture was white... but i would think that any ubercheap pot that holds water would serve. so if I've a bunch of normal pots i would just grab some fabric, a stapler, and go for it. I'm actually curious as to how this would/could be adapted to one of those feed to waste with no waste auto valve dealios. coco+perlite+drip to waste?
now! as to the air-pots. i think one might be able to fashion something very like that quite easily out of metal, tho coating it might be a bit tough. another option might be deforming a plastic bucket.
for this one i would not recommend that most consider my latest harebrained idea as good enough to try. I'm sure this is where the usual warnings go that if you don't do it carefully, and in the right area, you could ... well it might be bad and don't blame me
ok so get a 5gal bucket and grab a metal rod [iron might be good? like they use for branding, try not to burn yourself ;D] that has a cone shaped tip. take that and heat in flame or a hotplate or whatnot. it doesn't have to get white hot, a dull red should be enough. proceed to poke bucket from inside out, melting tip outwards, no need to poke through unless its easy [again not tried this one to date hehe]. when your happy that say every 2" there's an outward going cone shaped impression, do the same from the outside in in the area's between the one's going outwards. grab whatever is handy to open any cone tips you might need [file, sandpaper, dremmel, hand sander, or whatnot], do the same to the bottom of the bucket, and set that bucket inside another [so that there's air underneath] or just set it on two boards at the edges.
to visualize:
OK OK so! we now have a bucket that i would imagine that should serve us long time
