Boca Hydro Potassium Nitrate Greenhouse Grade 13.5-0-46.2 Water Soluble Plant Food For all Fruits and Vegetables

Boca Hydro Potassium Nitrate 13-0-46

High-Purity Nitrogen and Potassium Fertilizer for Vigorous Growth & Bloom

Boca Hydro Potassium Nitrate is a premium-grade, fully water-soluble fertilizer delivering 13% Nitrate Nitrogen (NO₃⁻) and 46% Soluble Potassium (K₂O). 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. Nitrate nitrogen promotes lush green growth without ammonium buildup, while potassium boosts flowering, fruit quality, and plant resilience.

✅ Chloride-free and safe for hydroponics
✅ Highly soluble and quick-dissolving
✅ Compatible with most other fertilizers and micronutrients
