Cultivation methods and precautions of hydroponic green radish

1. Water quality

The growth state of the green radish that has just been planted in the water is unstable and its immune system is relatively weak, so it needs to be maintained with relatively clean water. If you use tap water for maintenance, you need to air the tap water before using it, because there is chlorine in the freshly drawn water, which is not good for the growth of the plant. The purpose of airing is to release the chlorine. If conditions permit, mineral water can be used for maintenance.

2. Temperature

The temperature suitable for its growth is around 20 degrees, and it is best to maintain this temperature during maintenance. The maximum temperature cannot exceed 30 degrees and the minimum temperature cannot be lower than 10 degrees. If the temperature exceeds the limit, its growth will be hindered.

3. Lighting

It is not resistant to strong light, so it should avoid strong light when exposed to light. The sunlight in the morning and afternoon is relatively mild, so it can receive direct sunlight. It is generally necessary to avoid the sun at noon, and the daily sunlight time should not exceed five hours.

4. Watering

In addition to changing the water, hydroponic plants also need to spray water on the branches and leaves, especially in the summer when the temperature is relatively high, and the branches and leaves need to be sprayed with water in the morning and evening to cool down. There is heating in the north in winter, and the air is relatively dry, so it is necessary to water the branches and leaves every day to increase the humidity.

5. Fertilization

The nutrients in the water are limited and cannot meet the needs of the plants, especially during the period of vigorous growth. It needs to be fed with nutrient solution once every two weeks. When using, just pour it directly into the water. If you keep fish in the water, you should choose a nutrient solution that is harmless to the fish.

6. Notes

The growth rate of the green radish is relatively fast, so it needs to be pruned once in the spring to prevent the branches from being too long and to avoid concentrated nutrients. In addition, the inner wall of the container should be properly cleaned when changing the water.
