Product details

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

Premium-Grade Calcium and Nitrogen Plant Food

Boca Hydro Calcium Nitrate is a high-purity, greenhouse-grade fertilizer delivering 15.5% Nitrogen (N) and 26% highly available Calcium (Ca) – significantly higher than the 18–19% calcium in common double salt blends. Our ultra-refined formula provides superior solubility and cleaner performance in hydroponics, fertigation, foliar feeding, and container gardening.

Calcium is vital for cell wall strength, fruit firmness, and disease resistance, while nitrate nitrogen drives vigorous vegetative growth. Boca Hydro’s premium formulation ensures quick absorption with no residues – ideal for professional growers who demand precision and performance.

Sodium Free, Chloride Free, 100% Available Plant Macronutrients.

Perfect for Hydroponics, Drip Irrigation, Flood & Drain, NFT, DWC, Soil, Soilless, Coco, Foliar, Tower Gardens and Raised Beds.

Symptoms:

The most prevalent sign of calcium deficiency is blossom end rot, in which a plant or tree drops its fruit or buds and appears to rot at the tip.

Calcium Defeciency will also result in distorted growth and deformation of root tips, leaves, and shoot tips. In addition weaker plants are more suceptible to fungus and disease.

Other symptoms include distorted fruits that do not form correctly or partially rot while growing, low density of buds, significaly reduced quality, potency, flavor, yield of harvest and shortened shelf life.

Designed by plant science professionals and sourced from the highest quality ingredients to make the purest and cleanest product available.

Contains no harmful chemicals and will not damage or pollute soil or water in any way.

Easy to apply at every watering or fertilizing cycle or throughout the growing season.

Easy to apply with other nutrients. Approved for all fertigation and irrigation injection systems.

Avoid application and contact with sulfates and phosphates. (MKP or Sulfur)
