A little more on vermiculite and perlite I copied from somewhere:
Vermiculite is a alumino-silicate clay mineral that is mined and heated to expand the particles. It’s sterile, soaks up 3-4 times its volume in water, and attracts nutrients such as calcium, magnesium, potassium, and phosphorous.
Perlite, on the other hand, is a silicon-rich volcanic rock. It’s also mined and heated to expand the particles. It will soak up some water but is mainly used to aerate and improve drainage in potting mixes.
