The Magic of Kratky Hydroponics: Grow Your leafy greens in a Mason Jar!

Hello budding Tower farmers.



Today, we're going to dive into a slightly different form of 'ponics' - rather than aeroponic towers the world of hydroponics and specifically the Kratky method. If you're new to the term, don't worry, we'll break it down for you in a fun and easy way.

By the end of this post, you'll be ready to start your own mini hydroponic garden using just a mason jar and a seedling. So, let's get started!





What is Kratky Hydroponics?

Invented by Dr. Bernard Kratky, the Kratky method is a simple, passive hydroponic system perfect for beginners and those who prefer low-maintenance gardening. It doesn't require electricity, pumps, or wicks. Instead, it allows plants to absorb water and nutrients as they grow, creating an air gap that provides necessary oxygen to the roots. This method is ideal for leafy greens and herbs, but with some tweaking, it can accommodate other plants too.


Why Try Kratky Hydroponics?

  1. Simplicity: The Kratky method is straightforward and easy to set up. You don't need any complex equipment or technical know-how to get started.

  2. Low Maintenance: Once set up, the system requires minimal attention. Just sit back and watch your plants grow!

  3. Eco-friendly: It uses less water than traditional soil gardening, making it a sustainable choice for home gardening.

DIY Kratky Hydroponics: Mason Jar Edition

Now, let's get our hands dirty (or rather, clean, since there's no soil involved) and set up our own Kratky hydroponic system. Here's what you'll need:

  • A mason jar (or any other transparent container)

  • A seedling (we're using lettuce for this example)

  • Rockwool (a popular growing medium for hydroponics)

  • Hydroponic nutrients

  • A net pot

  • Aluminum foil or paint (to block out light)


Step-by-Step Guide

  1. Preparation: Soak the rock wool in water for a couple of hours. Then, make a small hole in the rock wool and gently insert your seedling. Make sure the roots are touching the bottom of the rockwool.

  2. Nutrient Solution: Fill your mason jar with water and mix in the hydroponic nutrients according to the package instructions.

  3. Set Up: Place the rockwool with the seedling in the net pot, and then place the net pot on top of the mason jar. The bottom of the rockwool should be touching the nutrient solution.

  4. Light Protection: To prevent algae growth, cover the jar with aluminum foil or paint it to block out light. Make sure to leave the top uncovered for the plant to grow.

  5. Growth: Place your setup in a sunny spot and watch your plant grow! Remember, the Kratky method is a set-and-forget system, so no need for daily watering.

And voila! You've created your own Kratky hydroponic system. It's that simple. With this method, you can enjoy fresh, home-grown greens right from your windowsill.
