Metode Kratky adalah teknik hidroponik pasif, non-sirkulasi di mana tanaman tumbuh di atas reservoir larutan nutrisi tanpa pompa atau listrik. Saat tanaman mengonsumsi larutan, celah udara terbentuk di bawah pot jaring, memberikan oksigen langsung ke akar.

- Lowest cost and simplest setup of any hydroponic method
- Best for leafy greens, herbs, and short-cycle crops
