Consistent Calcium Nutrition, Crop After Crop

Calcium Formate in a 4 lb resealable jar is the go-to size for dedicated home growers and small commercial operations running regular fertigation or foliar programs. With 30% calcium and 98% purity, you get a clean, nitrogen-free calcium source that won't throw off your nutrient balance — crop after crop.

Why Calcium Formate?

• Zero Nitrogen — Supplement calcium freely during bloom, fruit set, or late-stage finishing without excess N
• 30% Ca, 98% Pure — Dense calcium content means lower use rates and more applications per jar
• Fully Water-Soluble — Dissolves completely; no residue, no clogged emitters
• No Chloride, No Sodium — Safe for recirculating hydroponic systems and salt-sensitive crops
• Resealable Jar — Keeps product dry and free-flowing between uses

Best For

Ongoing calcium supplementation programs, tip burn prevention, blossom end rot correction, and post-harvest firmness improvement across vegetables, fruits, herbs, and specialty crop.

Application
