The Kratky method is passive hydroponics: plant in a net pot, roots reach a nutrient solution, air gap stays above the water line, and you mostly leave it alone. No pump — which means no hum in a studio.
Why apartments like it
- Silent
- Cheap to try
- Easy to move (no drilling)
- Teaches water + light without a $100 gadget
What you need
- Wide-mouth jars or a small Kratky kit
- Net pots + rockwool / sponges
- Hydro nutrient (follow dilute instructions)
- Clip LED if the sill is weak
- Waterproof tray under everything
Week-one checklist
- Germinate seeds in damp plugs until roots peek out.
- Set water line so roots touch liquid with an air gap for oxygen.
- Put jars on the tray under light 14–16h.
- Top up with plain water as the level drops; remix nutrients when growth stalls.
What not to grow first
Woody herbs (rosemary, thyme) are awkward in small jars. Start with lettuce, basil, or mint cuttings.
Key takeaway Kratky is a learning lane and a silence lane — not a replacement for every kit. If you hate measuring nutrients, buy a small Click & Grow after one successful jar cycle.
