Boca Hydro Potassium Nitrate – 13.5-0-46.2

Premium Water-Soluble Potassium & Nitrate Nitrogen Fertilizer

Boca Hydro Potassium Nitrate is a premium-grade, fully water-soluble fertilizer delivering Nitrate Nitrogen (NO₃⁻) and Soluble Potassium (K₂O) in one clean, fast-dissolving formula.

It is ideal for crops requiring fast-acting, immediately available nitrogen and potassium, making it perfect for fruiting vegetables, ornamentals, leafy greens, and flowering plants during mid-to-late growth stages.

13.5% Nitrate Nitrogen 46.2% Soluble Potash Water Soluble Greenhouse Grade Hydroponics Approved

Nitrate nitrogen promotes lush green growth without ammonium buildup, while potassium boosts flowering, fruit quality, plant resilience, and overall performance.

Chloride-free and highly soluble. Excellent for hydroponics, fertigation, drip irrigation, foliar feeding, pots, containers, greenhouse crops, and garden plants.

Product Benefits

High Potassium Nutrition	Supports flowering, fruit sizing, sugar movement, color development, crop quality, and overall plant strength.
Nitrate Nitrogen Source	Provides fast-available nitrate nitrogen for healthy green growth and efficient plant uptake.
Flowering & Fruiting Support	Ideal for potassium-demanding crops during bloom, fruit set, fruit fill, and heavy production stages.
Fully Water Soluble	Dissolves quickly and cleanly for hydroponics, fertigation, drip irrigation, foliar spray, soil drench, and hand watering.
Clean Fertilizer Source	Chloride-free and safe for hydroponics when used as directed. Compatible with many professional fertilizer programs.

Compatibility: Potassium Nitrate is commonly used with Calcium Nitrate, Magnesium Nitrate, and micronutrient products in complete fertilizer programs. Always dissolve completely and perform a small compatibility test when mixing with unfamiliar fertilizers, pesticides, or water sources.
