Hi Kristin, Beatiful growing and beautiful photos. For your succulents you can add not only a lot of perlite to the mix, but expanded clay (LECA) or volcanic cinders. This leads to much less heavy pots. Where people can get it, pumice is used, but there is no reason to ship pumice to a non-volcanic region when perlite and expanded clay are available.

Ordinary horticultural perlite with its small particle size retains a lot of water, so many C&S enthusiasts use large particle perlite. Be sure it is sold for horticultural purposes, because large-particle perlite is also used for insulation, and some of it has toxic levels of fluoride.
