i had a lot of problems with my 5 gallon fabric pot, soil would loose a lot of moisture everyday. They were perpetually under watered, the soil became hydrophobic, it was a mess. I think I mentioned it earlier but apparently you need larger fabric pots for them to really work. I switched to plastic pot bags and the rest was history. My worms don’t have a problem with plastic pots, as long as they have enough room. I did find one worm that escaped, but other than that I have never seen a mass exodus. Now I finish my plants in SIP’s and the worms like it.
I made this thread a long time ago and have learned much since. I recycle my soil and amend it each time, I store it in like a 20 gal bin. Works great. People will discourage others on breaking the soil up. In my system I take roots out and whole plant put them in a worm bin. The castings go back into my soil, so in a sense it comes back better. My only concern with recycling the soil is the nutrient content. I amend 1/2 the amount of coot’s mix and add more aeration. I use straw as a mulch and top dress with castings every other week or so. I think after the next crop is over I’ll get a soil test before I amend it
