What Is Kratky Method Hydroponics?

The Kratky Method is a simple, passive hydroponic system developed by Dr. Bernard Kratky. It operates without electricity, pumps, or aeration systems by using a single container filled with nutrient-rich water where plant roots are partially submerged.

The method allows the roots to access both water and oxygen by maintaining a static nutrient solution that decreases as plants absorb nutrients.

This passive system is unique in hydroponics as it requires minimal maintenance and is suitable for growing plants that don’t require constant water circulation.

Who Created The Kratky Method Of Hydroponics?

Dr. Bernard Kratky, a researcher at the University of Hawaii, developed the Kratky Method. His work focused on creating a low-cost, low-maintenance hydroponic system that could be used in areas with limited resources or in educational settings to demonstrate the principles of hydroponics.

How Does Kratky Method Hydroponics Work?

The Kratky Method works by suspending plants above a nutrient-rich water reservoir. As the plants grow, their roots extend into the solution, absorbing water and nutrients.

As the water level drops, a gap forms between the water surface and the plant roots, providing the necessary oxygen. This method is ideal for leafy greens and other fast-growing plants.

A Kratky hydroponics kit typically includes:

• A container or reservoir with a lid
• Net pots or plant holders
• Growing medium
• Nutrient solution mix
• pH test kit or pH adjusting solutions

These kits provide everything needed to start a Kratky hydroponic garden and are available for purchase from various gardening and hydroponic supply stores.

Setting Up Kratky Hydroponics Kit

1. Container Setup: Plants are grown in a container (such as a bucket or reservoir) filled with a nutrient solution.
2. Roots and Water Level: Initially, the roots are partially submerged in the nutrient solution. As the plant grows, it absorbs the nutrient solution, and the water level decreases.
3. Air Gap: An important feature of the Kratky method is the air gap between the top of the nutrient solution and the bottom of the net pot or growing media. This gap allows oxygen to reach the roots, promoting healthy growth.
4. No Aeration or Pump: Unlike other hydroponic systems, the Kratky method does not require aeration or pumps because it relies on the gradual consumption of the nutrient solution by the plant and the oxygen available in the air gap.

Kratky Method Nutrient Solution

What Is the Nutrient Mix for Kratky Method?

The nutrient solution for the Kratky Method should provide all the essential macro and micronutrients required for plant growth.  A common nutrient mix for leafy greens includes:

• Nitrogen (N): 150-200 ppm
• Phosphorus (P): 50-75 ppm
• Potassium (K): 150-200 ppm
• Calcium (Ca): 150-200 ppm
• Magnesium (Mg): 50-75 ppm
• Sulfur (S): 50-75 ppm

The solution should contain trace elements like iron, manganese, zinc, copper, molybdenum, and boron. Commercial hydroponic nutrient solutions are available and typically provide the correct balance of these nutrients.

The nutrient solution for the Kratky method needs to be carefully balanced to provide all essential nutrients required for plant growth.

Best Plants For Kratky Method

The Kratky Method is best suited for:

• Leafy Greens: Lettuce, spinach, kale, and Swiss chard are ideal for the Kratky method due to their relatively shallow root systems and fast growth.
• Herbs: Basil, cilantro, parsley, and mint also thrive in the Kratky method.
• Some Fruiting Plants: Compact varieties of tomatoes, peppers, and strawberries can also be grown using the Kratky method, though they may require larger containers and more nutrient solution.

These plants thrive in the Kratky system due to their fast growth and relatively low nutrient requirements.
