Can you wash them in the washing machine? Are they hard to clean?
How well do they work for perennial plants in winter? They are pretty airy after all, does this insulate the cold, or makes it even more destructive for the hibernating roots?
How long do they last under those conditions? Will they disintegrate after some time and shed microplastics?
Do they dry out significantly faster than regular pots? How is the water consumption?
When using coco coir, should I use less perlite?

Thanks a lot!

I've been using them for the past couple years and they've lasted so far. Can't say anything beyond that yet.

Overall I've had a good experience. They are space efficient when not in use, reduce girdling root issues, and are cheap. Biggest issue is that they do dry out a little faster but it's a minor thing.

I'm sure they will turn into microplastics eventually but so does every plastic option. Terra cotta would be really your main option if you want to avoid that.

Thanks! Then, I'll try them.

Terracotta isn't my thing. It breaks too easily, especially when it freezes.

Should I include less perlite (10 instead of 30% v/v) in bigger pots when using fabric? Is the aeration/ air pruning significantly better?

I haven't really changed my potting blend so I'm not too sure on that one.

I've found the air pruning effect is noticeable. The prop-tek air pruning pots are the best but too pricy for me.
