Spongelei water retention crystals absorb and release water in the soil. Spongelei™ is a product used as a delivery system to release water into all types of potting soil. It absorbs water, similar to a sponge and slowly releases moisture as the surrounding soil dries out. Mix into soil when planting and water immediately after until saturation is reached.  Ideal for all plantings, indoor and outdoor: containers, baskets, trees, shrubs, vegetables, flower beds, greenhouses, and turf. 

• Reduces water stress in plants and helps protect plants during hot weather or drought

• Environmentally friendly, biodegrading into potassium, CO2, and water.
