I found it!
The perfect self-watering pot for my strep. It's basically like the self-watering AV pots that have an outer and inner pot (glazed and unglazed, respectively). It's 6" in diameter, generously tall, and the perfect shade of green. So, I'm wondering now just what kind of potting mix I put in it. When I put my AV's in the 4" AV pots, I have to take soil off the root ball for them to fit. My strep is in a 4" pot now, and will be sizing up dramatically. (But I don't think it will be overpotted . . . this plant just keeps on growing and growing).
Anyway, should I just get a bag of good AV mix and add 50% perlite, or what?
Thanks so much for your help. Sooner or later I'm going to post pics of my gessie seedlings so I can figure out just what they are, and how to care for them.
Take care, and have a great weekend!
