My media mix with 3 major component:
- A. Charcoal from rice husk
- B. Mix of red and black lava rock
- C. Mix of pumice, perlite, and akadama (depends on what available)
- some compost and small amount of balanced fertilizer
The mix will be 2 cups of A + 2 cups of B + 2 Cups of C + 1/2 cup of compost and 1/2 spoon of fertilizer, so far the succulents are quite happy with this mix
