Why should you grow radishes in an aquaponic system?

Radishes are perfect vegetables for meals. They can be eaten raw or mixed in during cooking. They can be added to healthy juices or incorporated in salads.

Factors and Considerations

To many people, aquaponics systems seem like a lot of work and very tedious ventures, especially at the start. However, the key to a successful aquaponics system is following the specific requirements for the entire system- fish and crops. These are some important factors to help you grow radishes in an aquaponic system:

The kind of radish to grow

Most people are familiar with the red radish or the white daikon radish. However, there are other varieties that you can grow in your aquaponics garden depending on your preferences; black, watermelon, round, French breakfast, or horseradish. Some radishes are sweeter, while others are zestier.

The Aquaponics setup

The Aquaponics setup using wicking beds is an excellent way to grow radishes. With such beds, the roots of the radishes will get water adequately. They also allow for the plant to be hydrated successfully without the bulb getting soaked. Soaking alters the flavor and can cause the loss of the desired crunchiness. Since radishes like cool temperatures, you can have tilapia or use koi. 

Planting

Planting the radish seed germination rate is 80% which makes them very easy to grow. Sprinkle the seeds on your preferred growth medium and provide a spacing of 2-4 inches. 

The pH requirements

Radishes will typically flourish with a water pH of between 6-7.

Temperature and sunlight

Radishes grow well in a cool environment. An ideal temperature would be 60-80 degrees F. If you go beyond this range, the bulb growth can stop. Expose the radishes to full sunlight for at least 6 hours daily.

Harvesting

Based on how well you regulate the required growth factors, you can harvest the radishes 45-75 days into planting. Varieties may have variable harvest times. 

Final Thoughts

The only thing to ensure is that you keep the factors that favor their growth maintained and under control. Add in the effort and watch your radishes thrive.
