Ideal Rooting soil Mix ???

[BobCt]

For my abundant Opuntias and Euphorbias is there an ideal rooting mixture such as Desert sand, Pumice, Perlite, Clean topsoil or constituents that are the chosen best for successful rooting ? Right now I am running about 50/50 with rooting success, meaning healthy dense roots versus sparse short length roots. Is there any benefit to using rooting hormone to tip the success scale in my favor ?
