Boca Hydro Magnesium Nitrate – 10% Mg + 11% N (Nitrate Nitrogen)

Premium-Grade Magnesium & Nitrate Supplement for Plants

Boca Hydro Magnesium Nitrate is a high-purity, fully water-soluble fertilizer providing essential Magnesium (Mg) and Nitrate Nitrogen (NO₃⁻) – two key nutrients for photosynthesis, chlorophyll production, and overall plant vigor. Our advanced formula contains 10% magnesium and 11% nitrate nitrogen, ideal for correcting magnesium deficiency and promoting lush green growth in all crops, especially under hydroponic or fertigation systems.

Sulfur-free and chloride-free. Safe for all crops, from leafy greens to citrus and flowering plants.

Supplies both magnesium and nitrate nitrogen in highly available forms.
Supports chlorophyll formation and photosynthetic activity.
Improves nutrient uptake and flower development.
Excellent compatibility with calcium nitrate and potassium nitrate.
100% soluble – ideal for hydroponics, fertigation, soil drench, and foliar feeding.

Unlike Magnesium Sulfate, Magnesium Nitrate can be combined in concentrate (dry or liquid) and applied with Calcium Nitrate and will not clump or lock.
