Horticultural Vermiculite is a natural, non-toxic silicate mineral. After high-temperature exfoliation, its unique layered structure provides excellent water and nutrient retention, as well as aeration. Our vermiculite for plants is lightweight with a high cation exchange capacity (CEC), effectively adsorbing nutrient ions like ammonium and potassium and releasing them slowly for plant uptake. Common particle sizes range from 1-3mm to 2-4mm, with customizations available. Widely used in soilless culture, seedling nurseries, soil conditioning, and rooftop greening, it significantly promotes root growth and transplant survival. Whether used alone for cuttings or mixed with peat and perlite, vermiculite is a core component of an ideal growing medium. Quality vermiculite creates a loose, aerated, and nutrient-rich microenvironment for plant roots.
