With the Botanicare Supplements Kit, gardeners receive one, eight-ounce bottle each of Cal-Mag Plus, Sweet and Clearex. Cal-Mag Plus (2-0-0) works to prevent calcium and magnesium deficiencies in plants and also contributes iron, boron, zinc, manganese, molybdenum, copper and cobalt. AquaShield bio-fungicide guards against damping-off disease and root rot while Clearex leaches potentially toxic salt deposits. Help customers pair this kit with the Pure Blend Pro Soil or Hydro Kit for a complete fertilization program that doesn't break the bank.
