The Complete Nutrient Solution for Vigorous Growth and Healthy Yields Whether you are a home gardener, a hydroponic enthusiast, or managing a large vegetable patch, providing your plants with the right balance of nutrients is critical to success. Calcium Nitrate 15.5-0-0 is a premium, professional-grade fertilizer designed to deliver two essential nutrients your plants need most: Nitrogen and Calcium. Unlike all-purpose fertilizers that rely on slow-release mechanisms, this 100% water-soluble formula goes to work immediately. It provides a pure source of nitrate nitrogen—the form plants can absorb instantly—combined with soluble calcium to strengthen plant structure from the roots up. This dual-action formula ensures your plants don’t just grow fast; they grow strong, resilient, and productive. Why Choose Calcium Nitrate? 1. Prevent & Correct Blossom End Rot One of the most frustrating issues for gardeners is Blossom End Rot—those dark, sunken spots that appear on tomatoes, peppers, eggplants, and squash. This condition is caused by a calcium deficiency during fruit development. Our Calcium Nitrate fertilizer delivers a readily available source of 19% calcium to help prevent this disorder before it starts, ensuring your harvest is healthy, market-ready, and blemish-free. 2. Instant Nitrogen Availability The nitrogen in this formula is 100% nitrate-based. Unlike ammoniacal nitrogen (which can be lost to the atmosphere or require soil bacteria to convert), nitrate nitrogen is absorbed immediately by the root system. This results in rapid greening, vigorous vegetative growth, and quick recovery from transplant shock or environmental stress. 3. Strengthen Cell Walls & Improve Shelf Life Calcium plays a vital role in building strong cell walls. Adequate calcium levels result in: Stronger stems that resist lodging (falling over). Improved fruit firmness and resistance to bruising. Extended shelf life for harvested fruits and vegetables. Better disease resistance against fungal pathogens. 4. 100% Water-Soluble & Versatile Engineered for purity, this fertilizer dissolves completely in water with no residue or clogging. It is suitable for a wide range of application methods: Hydroponics: A staple nutrient for commercial and hobby hydroponic systems. Foliar Spray: Mix with water and spray directly onto leaves for rapid nutrient absorption. Drip Irrigation / Fertigation: Safe for use in irrigation systems without clogging emitters. Soil Drench: Apply directly to the root zone for sustained uptake. Guaranteed Analysis: Total Nitrogen (N): 15.5% 15.5% Nitrate Nitrogen Calcium (Ca): 19% Derived from: Calcium Nitrate Formulation: 100% Water-Soluble Crystalline Powder Application Rates & Instructions: Note: Application rates vary by plant type and growing method. Always perform a small test before a large-scale application. For Soil & Vegetable Gardens: Mix 1 to 2 tablespoons per gallon of water. Apply every 2 to 3 weeks during active growth and fruit development. Water the soil around the base of the plant thoroughly. For Hydroponics: Use as part of a balanced nutrient solution. Mix at a rate of 150–200 ppm (approximately 1–2 teaspoons per gallon of water), depending on the growth stage and other nutrients in your system. For Foliar Spray: Mix 1 tablespoon per gallon of water. Spray leaves thoroughly in the early morning or late evening to avoid leaf burn. Avoid spraying during peak sunlight hours. For Lawns (Greening): Apply 2 to 5 pounds per 1,000 square feet diluted in water via a sprayer, or apply lightly before irrigation. Use every 4–6 weeks during the growing season. What’s Included: 25 Lb of High-Purity Calcium Nitrate Fertilizer Key Benefits at a Glance: Feature Benefit 15.5% Nitrate Nitrogen Instant uptake for rapid green growth and stress recovery. 19% Soluble Calcium prevents blossom end rot, strengthens cell walls, and improves fruit quality. 100% Water-Soluble No clogging; ideal for hydroponics, drip systems, and foliar sprays. Professional Grade High purity with minimal insoluble matter. Versatile Use Works for vegetables, fruits, ornamentals, turf, and cannabis. Frequently Asked Questions: Q: Will this fix Blossom End Rot once it appears? A: While it cannot repair fruits already affected by blossom end rot, it will provide the necessary calcium to correct the deficiency for subsequent fruits, preventing the disorder on new growth. Q: Is this safe for hydroponics? A: Yes. Calcium Nitrate is a foundational component in almost all hydroponic nutrient formulations. It is fully soluble and mixes well with other fertilizers (except sulfates and phosphates, which should be mixed separately to avoid precipitation). Q: Can I use this on my lawn? A: Absolutely. The high nitrate nitrogen provides a quick green-up without excessive growth flushes, making it excellent for turf management. Q: How should I store this product? A: Store in a cool, dry place with the bag tightly sealed. Calcium Nitrate is hygroscopic, meaning it absorbs moisture from the air; keeping it sealed ensures it remains a free-flowing powder.
