In almost all of my plants I use perlite and SPM. I went to a garden center and asked for sand once and they gave me a bag of top dressing sand for cacti. It is very fine stuff and I'm not sure it is OK to use. I doesn't say what it is composed of, I thought I read that you should use silica sand. Is the sand you buy for kids' sand boxes OK?
