Sorry if this has been asked before:
I have always used Silica sand, also sold as Quartz silica sand in my CP mix. The main reason for this being that it is readily available, as it is sold in 50lb bags under many brands for a host of different applications. The other reason being I know it is free of unwanted contaminates.
The silica sand is very very fine, is their any benefit to using a courser sand? The bulk of my sand usage is for Drosera, however I am interested in hearing thoughts on other forms of CP's as well (Dionaea, Cephs,Sarrs...).
Thanks for letting me pick your brains,
