DIY Unlimited Kratky Hydroponics: Easy Gravity Fed System for Automatic Refills

Description: In this video, I’ll show you how to build a fully automated Kratky hydroponics system designed to be completely passive during the growing season. Using a gravity-fed design with float valves and tub outlets, this setup ensures a consistent nutrient supply with minimal effort. While I’m using this system for an outdoor tomato grow, it’s versatile enough to work with other crops like chillies, capsicums, peppers, cucumbers, lettuce, basil, and more. What You'll Learn in This Video: Setting up a gravity-fed system with 20L buckets. Installing float valves and tub outlets for automatic nutrient regulation. Using net cups and substrate for tomato seedlings. Managing outdoor challenges like rain and temperature fluctuations. Hardware and Parts Used in This Build: 20L Buckets: For holding the nutrient solution. Float Valves: To regulate the nutrient level automatically. Tub Outlets: Positioned for gravity-fed drainage. 13mm Poly Tubing & T-connectors: For nutrient distribution between buckets. Step Drill Bit: For creating precise holes for outlets and valves. Net Cups: To securely hold tomato seedlings. Substrate: Clay pebbles to support root growth. Teflon Tape: To ensure leak-proof seals. 500L Nutrient Reservoir: A central tank to feed all buckets. Mulch: For outdoor protection and temperature regulation.
