thank you I was thinking about cutting the bottoms off to grow new roots. But just laying em I like that better. :) What are they called? The one with your cacti pups.

The Haworthia with the cacti pups is a H. truncata. I'm not the biggest Haw fan, but I find truncatas really beautiful:). The two baby cacti are both a Trichocereus 'Paramount Hybrid' and then the the bigger one is a Rebutia I forget what species:).

Beautiful! So they will survive on purely pumice so will they do well with lava rock? Just got em and I have a easter Lily cacti waiting for replanting.

Ya they would do fine in lava rock as long as the lava rock is about the same size as the pumice. If they're big pieces of lava rock that wouldn't work;).

My normal mix for cactus is about 60%-70% pumice and 40%-30% cactus mix. I just bought some perlite and I think I'm gonna start adding some perlite in the mix. Just because I go thru pumice so freakin fast. I'm always buying big bags of pumice. Plus the perlite lightens up the pot. So I'm gonna have to experiment. For a general arid cactus mix I'm going to try 50% pumice 20% perlite and 30% cactus mix. I may have to adjust so we will see:). I pretty much use cactus soil as filler.

This is usually what my mix looks like:). A good sucvulent mix should fall apart in your hand.

Let me know how it goes! I realized I don't like 50/50 with c&s and perlite cause they would float up top and then I'd worry about fast draining so yeah I ended up buying crushed lava rock online.

crushed granite chips are sold at Tractor Supply- don't get the crushed oyster shell, but get the granite, both are marketed by the same brand and are sold in feed stores and TSC.

Yup I've had thought of tsc, gonna be next stop for next soil mix trip.
