Hydrolite™ is a natural, silica-based, volcanic mineral with a unique, porous, crystalline structure which allows it to hold nutrients until plants need them. Hydrolite’s ability to retain essential plant nutrients and aerate the growing medium makes it an ideal amendment for both hydroponic systems and soil gardens.
