🌿 Hydroponic System Calculator
Plan your hydroponic garden with precision. Calculate nutrient solution mix ratios, pH targets, water usage, electricity costs, expected yields, and monthly nutrient expenses.
Hydroponic Calculator
Your Hydroponic System Estimate
How It Works
Our hydroponic system calculator uses established horticultural data to estimate nutrient requirements, water consumption, energy use, and crop yields for common hydroponic system types and plant varieties. Values are derived from university extension research and commercial hydroponics industry standards.
Nutrient Solutions & EC/PPM
Electrical Conductivity (EC) measures the dissolved salts in your nutrient solution, typically expressed in mS/cm or converted to PPM (parts per million). Different plants require different nutrient strengths: leafy greens thrive at lower EC (1.2–1.8 mS/cm), while fruiting crops like tomatoes need higher EC (2.0–3.0 mS/cm) during fruiting stages. PPM is roughly EC × 500 (using the 500 scale) or EC × 700 (using the 700 scale).
