Styrofoam Peanuts
Anyone heard that Styrofoam peanuts can cause problems when used in a mix or as drainage at the bottom of a pot? I read an article some time ago that suggested they are not good for orchids - that the Styrofoam released formaldehyde, and that the newer the Styrofoam the more it released. The article also suggested that perhaps chemicals, chlorine, flourine, etc., which are added to water supplies reacted with the Styrofoam. Like to hear what others think.
