EC ↔ ppm ↔ TDS — nutrient solution strength
Convert liquid nutrient electrical conductivity (EC) to parts per million (PPM) under Truncheon, 500 (TDS), or 700 (Hanna) scales.
pH buffer amount — solution volume ↔ ml of pH up/down
Estimate the volume of phosphoric acid (pH Down) or potassium hydroxide (pH Up) needed to adjust nutrient water reservoirs.
Nutrient dilution — concentrate ratio ↔ final EC
Calculate water and liquid concentrate volumes for multi-part hydroponic reservoirs to achieve target mixing ratios and EC.
Light intensity — PPFD ↔ lux ↔ watts per sq meter
Convert between Photosynthetic Photon Flux Density (PPFD/PAR), illuminance (Lux/Foot-candles), and grow light wattage requirements.
Growing medium volume — container size ↔ liters needed
Determine the volume of clay pebbles, coco coir, perlite, or soil needed in liters based on net pot size or grow container dimensions.
Water temperature ↔ dissolved oxygen capacity
Calculate the maximum theoretical dissolved oxygen (DO) saturation limits in water reservoirs across varying water temperatures.
