How to Use the Fertilizer Dilution Calculator
Our NPK to PPM calculator helps hydroponic growers, container gardeners, and greenhouse operators achieve precise nutrient mixing ratios. Whether you're growing tomatoes, lettuce, peppers, or ornamental plants, this tool converts your fertilizer's NPK values into exact measurements.
Step-by-Step Guide:
- Enter your fertilizer's nitrogen percentage - This is the first number in the N-P-K ratio (e.g., 20 in 20-10-10)
- Choose calculation mode - Select PPM for hydroponics or percentage for traditional gardening
- Set your target - Enter desired PPM (parts per million) for precise nutrient control
- Specify water volume - Enter the amount in liters or gallons
- Get instant results - See exact grams needed for your nutrient solution
Common PPM Targets for Hydroponics:
- Lettuce & leafy greens: 100-150 PPM nitrogen
- Tomatoes (vegetative): 150-200 PPM nitrogen
- Tomatoes (flowering): 100-150 PPM nitrogen
- Peppers: 150-200 PPM nitrogen
- Cucumbers: 150-200 PPM nitrogen
- Eggplant: 150-200 PPM nitrogen
- Strawberries: 100-150 PPM nitrogen
- Herbs: 100-150 PPM nitrogen
Why Accurate Fertilizer Dilution Matters:
Proper nutrient concentration is crucial for optimal plant growth. Too much fertilizer can burn roots and waste nutrients, while too little stunts growth. This calculator eliminates guesswork, ensuring your plants receive exactly what they need for healthy development.
Ideal for:
- Hydroponic systems (NFT, DWC, Ebb & Flow, Drip)
- Container gardening and potted plants
- Greenhouse production
- Indoor growing with grow lights
- Fertigation systems
- Foliar feeding applications
