What is the difference between Vermiculite and Perlite?


In use, vermiculte holds moisture. Perlite speeds drainage, gritty,
lightweight. Vermiculte is very good in getting woody cuttings to
root (never tried rooting with perlite but I guess it might work).
Both mediums are inorganic and sterile. For some reason it is harder
to find vermiculite for sale, perlite is availailable in many stores.
