Propagation, Clean Soil Mix
Clean Kitty Litter
Pumice is widely used to make lightweight concrete or insulative low-density cinder blocks. When used as an additive for cement, a fine-grained version of pumicecalled pozzolan is mixed with lime to form a light-weight, smooth, plaster-like concrete. This form of concrete was used as far back as Roman times. Clean Kitty Litter can be used on shop floors, for small seeding pots, light weight stone brick, etc.
