Growing Tomatoes With the Kratky Method
The Kratky method is an easy, low-maintenance way to grow tomatoes. It uses a self-watering container and requires no pumps or electricity, making it an ideal option for those with limited resources or space. Unlike traditional hydroponic systems, the Kratky method doesn’t require any regular maintenance since the water level remains constant.
Growing Hydroponic Tomatoes Using the Kratky Method in Mason Jars
To begin, you’ll need a container with drainage holes drilled into the bottom. A plastic storage bin works well for this purpose. Fill the container with a soilless growing medium such as coco coir or peat moss. You’ll also need tomato seedlings of your choice and enough nutrient solution to fill the container up to about two inches from the top of the container.
Once the container is filled and the seedlings are planted, fill the remaining two inches of the container with water and add a few drops of pH adjuster if needed. Place the container in a sunny location and allow it to sit for one to two weeks until roots have grown into the nutrient solution. During this time, check that there is enough water in the container every few days.
After two weeks, you can begin feeding your tomatoes. Slowly pour additional nutrient solution into the container at regular intervals for about four weeks or until your plants start producing fruit. Make sure to keep water levels consistent throughout this process as over-watering can damage tomato roots. Once fruit begins appearing on your plants, you won’t need to water them any more as the plants will draw the moisture they need from their roots.
The Kratky method is a great way to grow tomatoes with minimal effort and resources. With this low-maintenance system, you can be sure to have delicious home-grown tomatoes all season long! Try it out today and enjoy the taste of success.
Steps to Grow Kratky Tomatoes
• Establish the container—Set up a container with net pots, hydroton beads, and water.
• Start seeds in water—Soak tomato seeds in warm water for 24 hours before planting them.
• Plant the seeds—Gently place two or three tomato seeds into each net pot filled with hydroton beads.
• Add nutrient solution—Fill the container with a nutrient solution such as fish emulsion or an organic fertlizer to feed the plants while they’re growing.
• Monitor growth level—Check periodically to monitor and adjust the nutrient levels and pH balance in the container if necessary.
• Harvest tomatoes when ready—Wait until tomatoes are ripe and ready to be harvested, then enjoy the fruits of your labor!
• Repeat—Empty and clean the container out after harvesting and start the process over again for a new crop of tomatoes.
Nutrients for Hydroponic Tomatoes
Tomatoes grown in the Kratky method require the same basic nutrients a regular hydroponic tomato needs. These include nitrogen, phosphorus, potassium, calcium, magnesium, iron, and trace elements such as boron, zinc and manganese.
When growing tomatoes with the Kratky method you’ll need to use a fertilizer that is available in liquid form. You can either buy this pre-mixed or make your own using commercially available powders. The concentration of the nutrient solution should be kept between 1-2 EC (electrical conductivity) for optimal growth and fruiting.

You can also add additional minerals such as dolomite lime and Epsom salts to buffer the pH of the nutrient solution, which is especially important when using tap water. It’s best to add these minerals at the start of your tomato crop cycle and adjust as needed throughout the season.
Finding Hydroponic Tomatoes Fertilizer
If you’re having trouble finding a fertilizer specifically designed for hydroponic tomatoes, it’s also possible to use a basic hydroponic nutrient solution that is designed for lettuce or other leafy greens. Just be sure to check the label before purchasing to make sure it provides all the necessary nutrients tomatoes need.
Kratky Tomatoes are very prolific and you can even clone the plants easily in this method. By following these tips, you can easily grow delicious Kratky tomatoes in no time! So get started today and enjoy fresh home-grown tomatoes any time of year.
Kratky tomato gardening is a hydroponic method developed by Dr. Bernard Kratky, an agricultural researcher from the University of Hawaii. It is a simplified form of hydroponics that does not require electricity, pumps, or complicated nutrient systems. Instead, it relies on the principle of passive water delivery to provide plants with the necessary nutrients and water.
Here’s how Kratky tomato gardening works:
Container Setup: Start by choosing a suitable container for your tomatoes. It can be a plastic bucket, a large food-grade container, or any other vessel with a lid. Make sure the container is clean and has enough capacity to hold the roots of your tomato plants.
Nutrient Solution: Prepare a nutrient solution by mixing a hydroponic fertilizer into water. The fertilizer should contain a balanced blend of essential macronutrients (nitrogen, phosphorus, potassium) and micronutrients (calcium, magnesium, iron, etc.). Follow the instructions provided with the fertilizer for proper dilution.
Planting: Germinate tomato seeds in a separate container filled with a seed-starting mix. Once the seedlings have developed a few leaves, transfer them to the main container. Make a hole in the lid of the container and place the seedling, ensuring the roots are submerged in the nutrient solution.
Water Level: Initially, the container should be filled with the nutrient solution up to the bottom of the lid, allowing the roots to come into contact with the solution. As the plant grows and consumes water, the level of the solution will gradually decrease.
Air Gap: The Kratky method utilizes an air gap between the bottom of the lid and the nutrient solution. This gap allows oxygen to reach the roots, preventing them from becoming waterlogged. The size of the air gap should be sufficient to supply oxygen to the roots while still maintaining contact with the nutrient solution.
Light and Temperature: Place your Kratky tomato garden in an area with ample sunlight or provide artificial lighting if necessary. Tomatoes require at least 6-8 hours of direct sunlight per day. Maintain a suitable temperature range for tomato growth, ideally between 60°F (15°C) and 85°F (29°C).
pH Monitoring: Regularly check the pH level of the nutrient solution using a pH meter or test strips. Tomatoes prefer a slightly acidic pH between 5.5 and 6.5. Adjust the pH using pH-up or pH-down solutions if necessary.
Maintenance: Monitor the nutrient solution level and top it up as needed. Refill the container when the solution is almost depleted. Be cautious not to overflow the container, as it can lead to oxygen deprivation.
Pruning and Support: As your tomato plant grows, provide support such as stakes or a trellis system to prevent it from toppling over. Prune the plant by removing suckers and maintaining a single main stem to promote stronger growth.
Harvesting: Tomatoes grown using the Kratky method will eventually produce fruit. Harvest them when they are ripe and enjoy your homegrown tomatoes.
Benefits of Kratky Tomato Gardening:
It is a simple and low-cost hydroponic method suitable for beginners.
It eliminates the need for complex equipment and electricity.
It allows for water conservation as the system is closed, and water is not continuously circulated.
It can be used in areas with limited access to fertile soil or where traditional gardening methods are challenging.
However, it’s important to note that the Kratky method is not suitable for all plant types, and it may have limitations in terms of plant size and growth. It is primarily recommended for smaller plants like lettuce, herbs, and certain varieties of tomatoes.
