From Small Spaces, Mighty Brews:
A Complete Guide to Indoor Herbal Teas with the Kratky Method
Even without a sprawling garden or backyard, the soothing, healing world of herbal teas is well within your reach. Thanks to the Kratky method, a simple and passive hydroponic growing technique, you can cultivate a wide variety of beneficial plants right on a sunny windowsill, countertop, or shelf. Whether you live in an apartment, tiny home, or just want to grow indoors year-round, this guide will help you grow, brew, and enjoy your own herbal teas — fresh from your indoor garden.
🌱 What Is the Kratky Method?
The Kratky method is a passive hydroponic system that requires no pumps, electricity, or circulating water. Plants are placed in containers with a nutrient-rich water reservoir. Their roots hang into the solution, drawing up nutrients, while part of the roots remain exposed to air for oxygen. As the plant grows and uses the water, the water level drops, creating a natural air gap and eliminating the need for complicated equipment.
Why it's perfect for herbal teas:
-
Easy setup and maintenance
-
Great for small indoor spaces
-
Clean and soil-free
-
Allows for year-round growing
