Greatindos NPK 4:18:38 Hydroponic Fertilizer

Greatindos NPK is a premium-grade hydroponic and water-soluble fertilizer developed for the flowering and fruiting stage of high-value crops. This is an NPK 04:18:38, a low-nitrogen, high-phosphorus, high-potassium blend with chelated micronutrients, designed for tomatoes, peppers, cucumbers, leafy greens, and other fruiting vegetables. The low nitrogen content keeps leafy growth in check, while the high phosphorus and potassium drive strong root development, flower formation, fruit size, sweetness, and shelf life. Greatindos NPK is 100% water-soluble, leaves no residue, and works in hydroponics, drip irrigation, fertigation, soil culture, and foliar spray.

Key Features and Benefits of NPK 04:18:38:

• High Potassium and Phosphorus: NPK 04:18:38 supplies 18% phosphorus and 38% potassium, the perfect feed for flowering and fruiting crops.

• Low Nitrogen Profile: Greatindos NPK contains only 4% nitrogen, preventing excessive leafy growth during the fruiting stage.

• Chelated Micronutrients: NPK 04:18:38 fertilizer carries chelated Iron, Manganese, Copper, Zinc, Boron, and Molybdenum for fast and complete uptake.

• Better Fruit Quality: Greatindos NPK improves fruit size, weight, sugar content, flavour, colour, and post-harvest shelf life.

• Hydroponic-Grade Purity: NPK 04:18:38 fertilizer is 100% water-soluble greenhouse grade, with no oily residue or clogging in drip lines and emitters.

• Stronger Cell Walls: Greatindos NPK strengthens plant cell walls, supporting structural resilience and natural disease resistance.

• Versatile Application: NPK 04:18:38 fertilizer works in hydroponic NFT, DWC, drip irrigation, soil culture, coco peat, tower gardens, and foliar spray.

NPK 04:18:38 Fertilizer Uses:

Greatindos NPK is recommended for the following crop groups:

• Fruiting Vegetables (Tomato, Pepper, Capsicum, Chilli, Brinjal): Improves flower formation, fruit setting, fruit size, weight, and shelf life.

• Cucurbits (Cucumber, Watermelon, Bitter Gourd, Pumpkin): Boosts fruit development, sugar content, and uniform sizing.

• Leafy Greens (Lettuce, Spinach, Basil, Kale): Provides balanced nutrition for healthy growth in hydroponic and soilless culture.

• Fruits (Strawberry, Grapes, Pomegranate, Banana): Improves berry size, sweetness, colour, and post-harvest shelf life.

• Hydroponic Systems (NFT, DWC, Drip): Acts as Part B of the popular 3-2-1 feeding schedule paired with calcium nitrate and Epsom salt.

• Flowers and Ornamentals (Rose, Marigold, Gerbera): Boosts bloom count, flower size, colour intensity, and stem strength.

NPK 04:18:38 Fertilizer Dose:

Mix Greatindos NPK in clean water and apply by the suitable method. For hydroponics, pair with calcium nitrate and Epsom salt:

Note: Do not mix concentrated NPK 04:18:38 directly with calcium nitrate, as it causes nutrient lockout. Apply separately.

How to Use NPK 04:18:38 Fertilizer:

1. Take the right quantity of Greatindos NPK based on the application method and crop stage.

2. Pre-dissolve the powder in a small bucket of clean water and stir until fully dissolved.

3. For hydroponics, prepare Part B (NPK 04:18:38 + Epsom salt) and Part A (calcium nitrate) in separate stock tanks.

4. Add Part A to the reservoir first, stir well, then add Part B; never mix the two concentrates directly.

5. For foliar spray, dilute the dose and spray on both the upper and lower sides of leaves using a fine nozzle.

6. For fertigation, dissolve the product fully and run it through the drip line during regular irrigation.

7. Flush the drip line with clean water after each fertigation to prevent salt buildup.

8. Reseal the pack tightly after use and rinse the sprayer or mixing tank with clean water.

Best Time to Apply:

Apply NPK 04:18:38 fertilizer from the early flowering stage through to fruit ripening, when the crop demands extra phosphorus and potassium. For hydroponics, use throughout the reproductive cycle. Spray in the cool hours of early morning or late evening, and avoid the hot afternoon.

Frequency of Application and Re-entry Period:

• Frequency of Application: Apply Greatindos NPK every 7 to 10 days through foliar spray or fertigation during flowering and fruiting. In hydroponics, change the nutrient solution every 7 to 14 days for fresh feed.

• Re-Entry Period: There is no waiting period. Field work can resume once the spray dries or the fertigation cycle ends.

• Compatibility: NPK 04:18:38 fertilizer is compatible with most pesticides and fungicides, and pairs naturally with magnesium sulfate. Do not pre-mix with calcium nitrate, as the two react and form a precipitate that locks up the nutrients.

Safety Precautions and Handling:

• Never mix concentrated NPK 04:18:38 fertilizer directly with calcium nitrate in the same tank, as it causes calcium-phosphate precipitation and nutrient lockout.

• Always add nutrients to water and never the reverse, to avoid clumping or sudden temperature rise in the stock tank.

• Check EC and pH only after all nutrients are fully mixed; target pH 5.5 to 6.5 for most hydroponic crops.

• Keep the hydroponic reservoir between 18°C and 22°C, as nutrient uptake drops sharply outside this range and roots get stressed.

• Cover the nutrient reservoir with a light-proof lid, as direct sunlight causes algae growth and weakens chelated micronutrients.

• Wear chemical-resistant gloves, goggles, and a dust mask while measuring and pouring; the high potassium salt can irritate sensitive skin and eyes.

• Handle the pack with dry hands and use a clean scoop, as the crystals pick up moisture quickly.

Storage Instructions:

• Store Greatindos NPK 04:18:38 fertilizer in its original sealed pack in a clean, dry, moisture-proof place away from sunlight.

• Keep the product separate from food, animal feed, seeds, drinking water, and other agrochemicals.

• Always keep NPK 04:18:38 fertilizer out of reach of children, pets, and farm animals.

• Storage Temperature: Between 10°C and 30°C in dry conditions.

• Shelf Life: 2 years from the date of manufacture when stored sealed and dry.

Frequently Asked Questions (FAQs) — Greatindos NPK / NPK 04:18:38 Fertilizer:

Q1. Why is the nitrogen so low (4%) in NPK 04:18:38 fertilizer?

NPK 04:18:38 fertilizer is designed for the flowering and fruiting stage, when too much nitrogen causes excessive leafy growth at the cost of fruit. The low 4% nitrogen lets the crop focus its energy on flowers, fruit size, and sweetness instead of leaves.

Q2. Can Greatindos NPK be used in regular soil farming, or only in hydroponics?

Greatindos NPK works in both hydroponic systems and regular soil culture. It can be applied as a foliar spray, drip irrigation, fertigation, or soil application for tomato, capsicum, strawberry, and other fruiting crops grown in open field, polyhouse, or pots.

Q3. Why should I not mix NPK 04:18:38 fertilizer with calcium nitrate in the same tank?

Mixing concentrated NPK 04:18:38 fertilizer with calcium nitrate causes a chemical reaction between calcium and phosphate, forming an insoluble precipitate. This locks up nutrients and clogs sprayers. Always keep them in separate stock tanks and add to the reservoir one at a time.

Q4. Can Greatindos NPK 04:18:38 fertilizer be used for terrace gardens and pots?

Yes, Greatindos NPK 04:18:38 fertilizer is great for terrace gardens, kitchen gardens, and pots. Use 1 to 2 g per litre of water as a foliar spray or soil drench every 10 to 14 days during the flowering and fruiting stage for tomatoes, chilli, and other vegetables.
