Radishes are among the most popular vegetables that can be quickly grown hydroponically. Hydroponic gardening is a method of growing plants in a soil-less medium. Instead, the plants are grown in a nutrient-rich water solution that directly delivers nutrients to the roots. Hydroponic gardening is gaining popularity because it requires less space, water, and maintenance than traditional soil-based gardening. In this article, we will guide you through how to grow radishes hydroponically.

Select a suitable variety of radishes.

Radishes come in a variety of shapes, sizes, and colors. Some popular types of radishes suitable for hydroponic gardening are Cherry Belle, French Breakfast, and Early Scarlet Globe. You can choose various radish seeds that suit your taste and requirements.

Choose the correct container.

The first step in hydroponic gardening is choosing the correct plant container. You can use any sturdy and large container to accommodate your plants. Some popular options include plastic buckets, PVC pipes, and storage totes. You can also use specialized hydroponic containers designed for hydroponically grown plants.

Prepare the nutrient solution.

The nutrient solution is the key to hydroponic gardening. It contains all the nutrients your plants need to grow healthy and strong. You can purchase a pre-mixed nutrient solution from any hydroponic store or make your own nutrient solution at home using fertilizers.

To prepare the nutrient solution, you will need to mix the fertilizer in the right proportion with water. You can use a TDS meter to measure the strength of the nutrient solution. The ideal TDS level for radishes is between 800-1000 ppm.

Plant the radish seeds.

Once you have prepared the nutrient solution, you can plant the radish seeds. You can either plant the seeds directly in the hydroponic container or start them in a separate seedling tray. If you are starting the seeds in a separate tray, transplant them to the hydroponic container when they are around 2-3 weeks old.

To plant the seeds, make a small hole in the growing medium and place the source inside. Cover the basis with the growing medium and water it thoroughly. Ensure to maintain the right temperature and humidity levels to encourage faster germination.

Maintain the right conditions.

Radishes require the right conditions to grow healthy and strong. They prefer a temperature range of 60-65°F during the day and 50-55°F at night. They also need a relative humidity of around 60-70%. You can use a thermometer and hygrometer to monitor the temperature and humidity levels.

Maintain the nutrient solution.

The nutrient solution is the lifeline of your plants. You must maintain the proper pH and TDS levels to ensure your plants receive all the nutrients. The ideal pH range for radishes is between 5.5-6.5. You can use a pH meter to monitor the pH level of the nutrient solution.

You must also change the nutrient solution periodically to ensure it remains fresh and nutrient-rich. You can change the nutrient solution every 1-2 weeks or as required.

Harvest the radishes

Radishes are ready to harvest in around 20-30 days after planting. You can check the maturity of the radishes by gently pulling them out of the growing medium. The radishes should be firm, round, and free of cracks or blemishes.

Once the radishes are ready, you can harvest them by cutting off the leaves and roots. You can store them in the refrigerator for up to a week.

In conclusion, growing radishes hydroponically is a fun and rewarding experience. Following the steps, you can learn how to grow radishes hydroponically and set yourself up for success!
