I'm still trying to figure this out, because as much as I love everyone's input- I can throw crassula ovatta out my window and as long as I don't hit it with the lawn mower it will grow May to October, even on concrete..

There has got to be an easier way to do this. I have a gbarrage ( a garage full of garbage) with half bags of sand, play sand, pool filter sand, cement gravel, pea gravel, turface, Perlite, vermiculite, peat moss, long fiber spagnum moss, coair,, mulch from every tree on the planet, plus a yard full of dirt and leaf compost. I'm not buying any more varieties or brands Of dirt(ish))... . Not when I just bought 3 x $7 ea 3.5" inch diameter 6" deep Pots of echiveria, grapulatum and sedum that are clearly planted in typical potting soil, peat and perlite
