We’ve been searching long and hard for a calcium25 replacement. The wait is finally over! Grow-Cal is derived from non-synthetic calcium chloride and is amino acid chelated with no EDTA chelators used at all, meaning this is safe for microbes. We believe multiple sources of calcium create the best results when considering immediate and long term needs. Grow-Cal can be used not only as a foliar but also as a drench and we’ve seen great results doing both.

Due to the chelation, when used as a drench, Grow-Cal may also help with the availability of other forms of calcium. Calcium carbonate is one of the most abundant sources of calcium but it does take time to become bioavailable. Grow-Cal may increase the rate at which calcium carbonate and other forms, become plant available.

*This product is approved for use through the NOP program when dictated by a sap or soil test.


Application Rate:

Shake well before each use. Apply Grow-Cal in the early morning or evening while there is still dew on the plant. Avoid applying Grow-Cal in direct sunlight when temperatures exceed 86ºF (30ºC). Apply with high nitrogen amino acid products like Pure Protein Dry for even better results.

Fruit, Vegetables & Flower Gardens: Apply 12-16 oz of Grow-Cal per 1,000 sq. ft. of planting area before planting. *Hose end sprayers/injectors work best for this.

Soil Drench, Transplant, or Watering Solution: Dilute 2 oz of Grow-Cal per 1 gallon of water. Use 4 oz (1/2 cup) of the diluted solution per plant every 2-4 weeks.

Foliar Spray: Dilute 2 oz of Grow-Cal per 1 gallon of water and mist evenly onto plant foliage every 3 to 4 weeks. *Water as usual

Derived From: Non-synthetic Calcium Chloride. Soluble Calcium: 10%
