Bulk Calcium Nutrition for Commercial Operations

The 20 lb pail of Calcium Formate is built for commercial growers, greenhouse operations, and serious hobbyists who run high-frequency fertigation or foliar programs. At 30% calcium and 98% purity, it delivers a dense, nitrogen-free calcium source that scales efficiently — lower cost per application, fewer restocks, and consistent results across large canopies or multi-bench setups.

Why Calcium Formate?

  • Zero Nitrogen — Stack calcium without affecting your N budget — critical during bloom, fruit development, and late-stage finishing
  • 30% Ca, 98% Pure — High-assay formula maximizes calcium delivery per pound; ideal for high-volume mixing
  • Fully Water-Soluble — Dissolves completely with no residue — safe for drip, NFT, DWC, and foliar systems
  • No Chloride, No Sodium — Won't contribute to salt buildup in recirculating systems
  • Resealable Pail — Keeps product dry and free-flowing; easy to scoop and measure at scale

Best For

Commercial calcium supplementation programs, large-scale tip burn and blossom end rot prevention, post-harvest firmness protocols, and custom fertilizer blending across vegetables, fruits, herbs, and specialty crop.

Application

Pre-dissolve in water before adding to main reservoir or spray tank. Compatible with most water-soluble fertilizers. Suitable for fertigation, foliar, and hydroponic systems. Refer to label for crop-specific rates and dilution guidelines.
