I found these ceramic "upside down" planters online and ordered two of them. I like to use fresh herbs in my food and the thought of not having any while I traveled was disappointing. I hope these will provide at least basil and parsley. I am hanging them in my shower under the skylight. I will have to devise how to keep them from "clanking" or breaking while I am driving. Each planter has a clay reservoir at the top (bottom). At the end where the plant is, there is a round screen to hold the potting soil in and then a locking ceramic collar.
