The Environmental Factor Spongelei Water Retention Crystals
Best soil additive for gardeners looking to simplify plant hydration.
The Environmental Factor Spongelei Water Retention Crystals significantly improve soil structure and water management. These crystals absorb water, swelling to increase the soil's available water holding capacity. By slowly releasing moisture as the soil dries, they help reduce watering frequency by up to 50 percent, effectively protecting plants from water stress during hot weather or drought. Ideal for both indoor and outdoor use, this environmentally friendly product biodegrades into potassium, CO2, and water, helping to prevent both over- and under-watering issues in your garden.
