Of general interest on the subject of clay vs plastic pots, it may be relevant that we are in the process of repotting our very large cactus and succulent collection (thousands of taxa) in our Arid House and have decided to switch from traditional clay to black plastic. I could go into our reasoning but suffice it to say that the plants are responding well in the first year (or sooner). I'm begining to think that the main argument for clay is esthetics (but it's in the eye of the beholder). Paul Licht, Director Univ.
