The Kratky Method is one of the simplest and most beginner-friendly ways to grow hydroponic vegetables — no electricity, no pumps, and no moving parts.
🧪 How It Works
Plants are suspended above a nutrient solution with their roots partially submerged. As the plant grows and consumes the nutrients, the water level drops, creating an air gap that provides oxygen to the roots.
🛠️ Components You Can 3D Print
- Net pots (to hold the plant and grow media)
- Lids for jars or containers with built-in net pot slots
- Spacers or supports for stacking
🌱 Ideal for: Leafy greens like lettuce, spinach, and basil.
🇦🇺 Aussie Tip
Place the system in a sunny indoor spot or patio to avoid algae and evaporation. On the East Coast, late spring to early autumn is perfect for Kratky setups.
