DIY Kratky Method

What is the Kratky DIY Method and How to I Get Started?

The Kratky Method is a hydroponic technique that enables plants to grow in a nutrient solution without the need for pumps, aerators or other active mechanisms. This makes it an ideal choice for those looking to create their own hydroponic system at home, as it requires minimal setup and maintenance.

To get started with Kratky Method Hydroponics, you’ll need:


Kratky Method can be done in any watertight container that is big enough to accommodate the amount of water and plant you plan on growing.

Nutrient Solution

The Kratky method uses a nutrient solution instead of soil. You can buy pre-mixed solutions from your local garden center or create your own customized solution.

Seeds or Plants

Kratky Method works best with lettuce, tomatoes, cilantro, basil, leafy greens and most herbs. Other plants can be used as well, but will require more tweaking of the nutrient solution to find the optimal growing conditions.

The picture above shows my Kratky system which is a simple 2-shelf unit in my office. I use mason jars with net pots and clay pebbles to grow lettuce, tomatoes, herbs and more.

You can easily start from things you have on hand, such as empty food-grade glass jars and food containers with holes poked through them for net cups. The clay pebbles are hard to duplicate though I found, as they wick up moisture. When I got into Kratky a bit more, I bought some professional supplies and love them. These are the 4 things I would recommend should you wish to go that route as well.

You can see the top shelf, which is “open” allowing air into the enclosure. I use cardboard to block the light which can get bright and hot during the day. The second shelf below the open one has plants, it is just closed at the time the ic was taken.

Once you have all of your materials gathered, it’s time to get started!

Fill Container with Nutrient Solution

Start by filling your container with an appropriate amount of nutrient solution, making sure that there is enough space for the plant and its roots once it’s placed in the container.

Prepare Medium in Net Pot

Add clay pebbles or other medium to your net pot or otehr container with holes for roots to grow downward. The net cup or container should sit in the nutrient solution so the roots will touch.

Place Your Seedling or Plant

I use rockwool to grow seedlings and that works well to start seedlings in the container. Place the plant in the center of the container, ensuring that it’s securely in place and nestled into the growing medium. The rockwool should reach the nutrient solution so is can “wick” moisture to teh roots.

Monitor Nutrient Solution Level and Roots

Once the Kratky Method Hydroponics system is established, all you have to do is monitor your plant’s progress, top off the nutrient solution when needed, and check the roots. You want bright white roots, which indicate. a healthy plant.
