Hydroponic Lettuce Nutrient Guide: EC, pH and Fertilizer Ratios | Current Gardening Home > Hydroponic > Hydroponic Lettuce Nutrient Guide: EC, pH, and Fertilizer Ratios Explained Quick Answer: Hydroponic lettuce needs a nutrient solution at pH 5.8–6.2 and EC 0.8–1.0 mS/cm for seedlings, rising to 1.2–1.6 mS/cm for mature plants. The most important individual nutrients are nitrogen (100–150 ppm), potassium (150–200 ppm), and calcium (80–120 ppm) — calcium being the single element most responsible for tip burn when it falls short. What you’ll learn in this guide The exact EC range for each lettuce growth stage — seedling (0.8–1.0), vegetative (1.0–1.4), and mature head (1.2–1.6 mS/cm) — and why going…

Home > Hydroponic > Best Hydroponic Systems for Lettuce: NFT vs DWC vs Kratky Quick Answer: The ideal setup depends entirely on your cultivation scale; active Deep Water Culture (DWC) offers superior root thermal stability for hobbyists, while active Nutrient Film Technique (NFT) arrays maximize Energy-Use Efficiency (EUE) for commercial growers. Active NFT setups reach harvest maturity in exactly 28 days when maintaining a continuous root-zone temperature of 20°C and a pH of 5.8. What Most Guides Miss (And What You’ll Learn) NFT and vertical towers produce the fastest commercial harvests (28–35 days). DWC grows larger, more tender lettuce heads with highly reliable consistency. Kratky is the ultimate beginner-friendly system—no…

Quick Answer: Hydroponic lettuce typically takes 4 to 6 weeks from seed to harvest under optimal conditions. NFT and vertical tower systems are the fastest, often delivering harvestable lettuce in just 28 days. What Most Guides Miss Water Temperature is Crucial: Maintaining optimal water temperature (65-72°F) is vital to keep dissolved oxygen high. Nutrient Refresh: Simply adding water for evaporation isn’t enough; change the solution fully every 1-2 weeks. Light Spectrum: Balanced blue and red spectrums promote robust leaf development.
