  • Kratky Method for Hydroponic Lettuce (No Pump, No Electricity)

    Home » Hydroponics » Kratky Method for Hydroponic Lettuce (No Pump, No Electricity) Last Updated: August 08, 2026 | Reviewed for accuracy, clarity, and safety Quick Answer: In traditional active hydroponic systems (like DWC or NFT), water pumps or air stones continuously dissolve oxygen into the water. In the Kratky method, oxygen transfer occurs passively within the enclosed air gap. Relative humidity inside the sealed reservoir remains above 95%, preventing air roots from drying out while maintaining an aerobic environment that suppresses anaerobic pathogen proliferation. ⏱️ Time: 30 Minutes 💪 Difficulty: Beginner 💰 Est. Cost: $50 – $150 💡 Key Term The Kratky method for hydroponic lettuce is a non-electric…
