• How to Grow Radish Hydroponically

    radish Radishes are regular ingredients to salads as they provide a distinct taste aside from the nutrients that you can receive from eating the vegetable. Although quite easy to grow, you don’t usually see this type of root crop in many groceries in the United States of America. Quite popular in Asia, radish is a common crop planted in farms and gardens during the warm season despite being a cool weather crop. Indoor gardening though will allow gardeners to plant and grow the root crop all year round.

    Hydroponic system is an organic way of growing radishes either indoor or outdoor. It has lots of disadvantages compared to the disadvantages it presents to the gardener. One of its advantages is that it allows you to use minimal amount of water from sowing to harvest. The initial investment in setting up your hydroponic system is one of the disadvantages of using an alternative method of growing plants. In the long run though, its cons are usually outweighed by the benefits it provides to the gardener.


    Since hydroponic gardening is a soilless culture, you don’t have to worry about the type of soil you use on your garden. Set up your hydroponic kit instead by checking whether the mechanics are running in good condition or not. Start the pump to run a test on your gardening system. Turn off the pump after several minutes and prepare the growing medium for your seeds. You can expect best results if you plant and grow your radishes when the temperature is between 50 to 70 degrees.


    When sown in 60 degree temperature, the seeds of radishes usually sprout out of the growing medium within 3 to 7 days. Place each seeds on the holes of the media 8 to 10 inches apart to avoid overcrowding by the time they grow up and mature. The germination process usually takes place within a few days.


    The only thing you have to do when growing radishes on a hydroponic system is to supply the needed nutrients from seedlings until they mature. Avoid using fertilizers that are high in nitrogen as you can’t get the roots to grow big. Just like with other root crops, they require more growing medium as they need a large container as they grow up. Add more medium to your hydroponic system to support they as the radish grow bigger.

    You can also eliminate any infestation of weeds as much as possible to prevent them from competing with the radishes as they grow up.

    If grown outdoors during the spring, covering them up with something to keep them warm such as mulch will keep them warm. You can also move your hydroponic system if the radishes do not get the right amount of sunlight in their original location.

    Pests and Diseases

    When grown indoors, radishes do not usually get bothered by pests and diseases. Crops that are planted outdoor though are prone to flea beetles, root maggots, and other insects that tend to eat the leaves and roots. You don’t have to panic though as organic pesticides are enough to get rid of the problem. Diseases usually infest a hydroponic garden if proper sanitation has not been met.


    By the time the radishes are big enough, you can start harvesting them by pulling them out from the growing medium. Store the harvested radishes right away if you are not planning on eating them right away.
