Horticulture grade perlite derived from volcanic rock expands up to 10x when furnaced, creating a lightweight and porous growing medium (Supreme Horticulture).
Coco coir blocks expand 5x when hydrated, providing an alternative to sphagnum peat moss with increased nutrient retention (Hydro Crunch).
Perlite introduces pore spaces into soil/media for balanced air and moisture conditions around plant roots, minimizing chances of rot (Supreme Horticulture).
Both mediums can be used alone or blended with other organic materials like compost, bark, topsoil etc. for propagation and growing (Supreme Horticulture, Hydro Crunch).
Perlite is sterile, lightweight, non-toxic, pH neutral while coco coir is 100% organic fiber (Supreme Horticulture, Hydro Crunch).
