🌿 Boca Hydro Calcium Nitrate (15.5-0-0 + 26% Ca)

Premium Greenhouse-Grade Calcium & Nitrogen Fertilizer

Boca Hydro Calcium Nitrate is a high-purity, professional-grade fertilizer formulated to deliver 15.5% fast-acting nitrate nitrogen (N) and a superior 26% plant-available calcium (Ca) — far higher than the 18–19% found in standard double-salt products. Designed for hydroponics, fertigation, foliar feeding, and container gardening, our formula offers unmatched solubility, clean performance, and consistent results.

Calcium is essential for strong cell walls, blossom-end rot prevention, improved fruit firmness, and better shelf life, while nitrate nitrogen fuels vigorous vegetative growth without ammonium buildup. Boca Hydro’s greenhouse-grade purity ensures maximum absorption and precise nutrient delivery, making it trusted by commercial growers and home gardeners alike.
