I admit that I haven't read this thread post to post, but pots that use air pruning to terminate root tips should work, IF, and this is a big if, the ambient RH is fairly low. FWIW, copper hydroxide painted pots is foolproof. It always works.
Good luck,

Not to sound like a noob, but I assume you mean ambient "relative humidity"? I bet I'm outside the range you speak of. Right this second it's right at 50%. It's usually about 60%. After a watering it gets up into the 70's before coming back down. I let the soil get fairly dry.....but not dry. I've read a bunch of your work, like your sticky on moisture stress. I "think" I'm seeing evidence that letting the roots gets O2 is a good thing. It's tough to tell unless it's a controlled experiment.
