How It Works
Earthcare Water Crystals are tiny polymer particles that swell into gel-like water reservoirs when hydrated. Plants draw moisture from these crystals during dry periods, helping maintain consistent soil moisture and reducing stress during hot or dry conditions. The crystals release water and dissolved nutrients as needed, helping improve plant health and growth.
