Boca Hydro Chelated Calcium 14% (EDTA)

Premium Calcium Supplement for Healthy Growth and Maximum Yields

Boca Hydro Chelated Calcium 14% delivers a fully chelated, highly bioavailable source of calcium formulated with EDTA to ensure superior stability and efficient uptake in both soil and soilless systems. Calcium is essential for strong cell wall development, healthy root tips, fruit quality, and overall plant resilience.

This premium formulation is designed for hydroponics, fertigation, foliar applications, soil drenches, and container-grown plants. It rapidly corrects and prevents calcium deficiencies while improving plant structure, fruit set, and disease resistance.

Why Calcium Matters

Calcium is a critical macronutrient for plant growth and plays an important role in:

Strengthening cell walls for sturdier plants
Promoting healthy root development and new shoot growth
Supporting flowering, fruit set, and bud formation
Reducing the risk of blossom-end rot in tomatoes, peppers, and melons
Improving fruit quality, shelf life, and overall yields

Calcium Deficiency Symptoms

Plants lacking calcium often show visible signs, including:

Blossom-end rot and fruit drop
Deformed or misshapen leaves, buds, and root tips
Distorted, undersized, or partially rotting fruits
Low flower and bud density
Poor flavor, texture, and reduced shelf life
Increased susceptibility to fungal infections and disease
