TYVM to both, very helpful info!! I'm pleased to hear that the water can wick up so well. I thought if the wick was more than a few inches out of the pot that gravity would need to help but it does not sound like that is needed.
What about clay vs. plastic? Any tries with unglazed clay? I have 3 of those that are drying so often. I'll be moving those to bigger pots before it gets hot again next year, but whatever is in those pots is going to dry as quickly.
Will, do you prefer wool because it wicks more quickly, or evenly, or some other reason? I'm curious but would still be hesitant to use anything natural because of the way everything grows black mildew/mold here, when moist. Handy to have an alternative suggestion in case the nylon is disappointing.
