Plastic pots vs. clay pots. Advice from an article by Joyce Stork. Posted on the AVSA website
Most growers favor plastic pots for a number of reasons: 1) Constant water methods (wicking or capillary matting) work best with plastic pots. Clay pots allow too much evaporation and become covered with mineral deposit very quickly. Sometimes the soil will go dry at the top of a wick-watered clay pot, probably because the moisture is evaporating out the sides. 2) Plastic pots are more easily available in smaller and more squatty sizes. Violets seem to bloom best in pots that are about one-third the diameter of the leaves, and the roots do not extend much beyond two or three inches below the surface of the soil. 3) Plastic pots are less expensive to buy and easier to clean for reuse than clay pots. 4) The biggest problem with plastic pots is the sharp rim that cut leaves that rested on the rim. That can be resolved by selecting only pots which were designed with rolled edges. Clay pots seem to accumulate salts in the rim which burns leaves that come in contact. Now there are times when a clay pot is desirable-- most especially in hot climates or greenhouse growing. The evaporation from the clay works as a cooling device and actually keeps the roots cooler. Since many growers are in climate-controlled environments, this feature seems to be less important these days. Happy Growing! Joyce Stork

Since I am in a very hot climate maybe I should look into using clay pots, only problem can't find them in very small sizes.thanks for the article tip
