How does this look for potting mix? 2:1 inorganic to organic. the inorganic is 3 parts pumice, 1 part lava rock, 1 part turface. organic is equal parts coco coir and bark chunks. I plan on using it for my indoor cacti in 4" terra cotta pots. It looks very mineral heavy to me, but maybe thats ok?

Good potting mix besides the bark retaining moisture too long. But it also depends on the type of cactus you’re going to be potting this in. Normally you sift out the bark
Looks good. May throw in a little earth worm casting if you can get it but this is wonderfully gritty. Well done. Add tomato fertilizer to the top before you top dress your pots
For the inorganic your cocoa is good but you can add some worm castings
I personally don’t like bark in a cactus mix but I know growers much more experienced than I that use it (outdoors in a very low humidity environment). I personally would get rid of the bark and coir, add some decomposed granite and a little compost or worm castings. Desert cactus typically have very little organic matter in their native soil.
OK sans the bark
Would work fine with lithops or conos. Would not recommend for larger cactus/ succulent because the pumice is too small. I would recommend a something a little bigger for larger plants 4-6mm should be a good size.
One more thing, Since you’re also using terracotta I would also recommend extra organic to help with water retention since terracotta wicks water. And will dry out quickly
