Kratky Hydroponic Nutrients
Kratky fertilizer made for passive hydroponics. Mix once and grow lettuce, herbs, and greens with the kratky method no pumps, no fuss.
Why it works:
- 4-3-6 NPK — gently potassium-forward — steady growth with the root and stem strength potassium provides
- Sea kelp (Ascophyllum nodosum) for natural growth compounds
- Gentle liquid formula — mix it into your normal watering, no separate feeding routine
