How it works

Understanding the Kratky Method

The Kratky method is a passive hydroponic technique that allows you to grow plants without the need for pumps or electricity. This method is perfect for beginners and those looking to cultivate herbs in a sustainable way. By suspending plants above a nutrient solution, roots can access both air and water, promoting healthy growth. The Kratky method is cost-effective, easy to set up, and ideal for growing a variety of herbs in limited spaces. Using indoor grow lights, you can easily grow abundant herbs in a short amount of time.

The idea is simple. A net pot holds the plant in the lid of a container filled with nutrient solution, with the bottom of the pot just touching the liquid. As the herb drinks, the level slowly drops and leaves a pocket of air in the container. The upper roots breathe in that air gap while the lower roots keep drinking, so the plant gets oxygen without an air pump or bubbler. That is why Kratky herbs need no moving parts at all.

Getting started

Start Your First Kratky Herb Jar

Kratky herbs need only a container, a net pot, nutrients and light. Here is the whole setup in five steps.

  1. Pick a dark container

    A mason jar or plastic tub works. Opaque containers keep light off the solution, which stops algae.

  2. Mix the nutrients

    Fill it with water and a hydroponic nutrient made for herbs or leafy greens, mixed as the label says.

  3. Set the net pot

    Put a seedling or cutting in a net pot of growing medium in the lid, with the pot's base touching the solution.

  4. Give it light

    A sunny window or a grow light. Most herbs on this site do best with 12 to 16 hours of light a day.

  5. Let the level fall

    As the herb drinks, the level drops and an air gap forms for the roots. Harvest often to keep it bushy.

FAQ

Kratky Herbs: Common Questions

Which herbs can I grow with the Kratky method?

Many herbs thrive with the Kratky method, including basil, mint, cilantro and parsley. Each herb has its own needs for light and temperature, so check the guide for the one you are growing.

Do Kratky herbs need a pump or electricity?

No. The Kratky method is a passive hydroponic system. The plant sits above a nutrient solution and the air gap that forms as the level drops gives the roots oxygen, so there is no pump, air stone or timer. A grow light is the only thing you may want to plug in.

What type of container is best?

Opaque containers are ideal because they keep light away from the nutrient solution, which can cause algae growth. Make sure the container is large enough for the plant's root system.

Can I use tap water?

Tap water can be used, but it is best to let it sit for 24 hours so the chlorine can dissipate. Filtered or distilled water also works well.

Can I grow herbs indoors all year?

Yes. With the Kratky method and steady light and temperature, herbs such as mint can be grown indoors throughout the year.
