Powdered Oxygen. Grotek Oxy-Cal is a time-released supply of calcium and oxygen for the soil. Oxygen is a life-line for all living organisms and is required by all plants throughout their life cycle for optimum growth.

Oxy-Cal increases the microbial activity to provide a strong, disease-resistant growth medium. This enables the plants to better absorb and use the available nutrients and water.
