How Do You Grow Hydroponically with Mason Jars

To grow hydroponically with mason jars using the Kratky method, you will need mason jars, net cups, growing medium, nutrient solution, and plants. Start by filling a mason jar with the nutrient solution, ensuring that the bottom of the net cup touches the solution. Place the plant in the net cup filled with the growing medium, making sure the roots are submerged in the solution. As the plant grows, the roots will absorb the nutrients from the solution, promoting healthy growth without the need for a pump or electricity. The Kratky mason jar method is a simple and low-maintenance way to grow plants hydroponically, making it ideal for beginners and small-scale indoor gardening.


Begin by gathering the necessary materials, including mason jars with lids, growing medium (such as clay pellets or perlite), nutrient solution, and seeds or seedlings of your chosen plant.


Place the growing medium in the mason jar, leaving enough space for the roots of the plant. Insert the plant into the growing medium, ensuring that the roots are adequately covered and supported.

Nutrient Solution

Fill the mason jar with a nutrient solution specifically formulated for hydroponic systems. This solution provides essential nutrients to the plant, replacing the role of soil in traditional gardening.


Ensure that the roots have access to oxygen by either leaving the lid of the mason jar slightly open or using an aerator to provide oxygenation to the nutrient solution.


Place the mason jar in a location where the plant will receive adequate light for photosynthesis. If natural light is insufficient, consider using artificial grow lights to supplement.


Monitor the nutrient levels in the mason jar and replenish the solution as needed. Check for any signs of pests or disease and take appropriate measures to address them.


Depending on the type of plant being grown, harvest when the plant reaches maturity. Enjoy the fruits, vegetables, or herbs grown through your mason jar hydroponic system.


Mason jar hydroponics offers a compact and easily manageable way to grow plants indoors or in small spaces. It’s a great option for individuals interested in sustainable gardening practices or those looking to experiment with hydroponic gardening on a small scale.
