Each 8 x 4 x 2 inch brick is made from 100% coconut pith and fibers, compressing many times its expanded volume so a small package creates lots of usable substrate. Low electrical conductivity (EC) and a balanced pH make the coir easy to hydrate and blend into custom mixes for indoor and outdoor plants.\u003c\/p\u003e\n\n\u003ch3\u003eHow do Riare coir bricks expand and prepare for planting?\u003c\/h3\u003e\n\u003cp\u003eRehydration is simple: add water and let the brick absorb and break apart into a loose, fibrous medium within minutes.
