Do I need to change the water frequently when growing green radish in water?

1. Change water frequently in the early stage of hydroponics

The growth rate of hydroponic green radish is very fast. When it is first cultivated, it has not yet taken root and needs to be changed water frequently. The water can be changed every 2-3 days, or every other day. Please note that the water temperature should be close to the room temperature and there should not be too much difference, which will affect the growth of the root system.

2. Frequency of water change after rooting

After the hydroponic green radish takes root, the water does not need to be changed too frequently. Normally, you only need to change the water once a week, or every 10-15 days. If you find the water becomes turbid, you should change the water in time. After rooting, you can add a few drops of nutrient solution when changing the water. At this time, green impurities will appear in the container, so be sure to clean it.

3. Notes

1. Water quality: Clean spring water is required for hydroponic green radish. You can also store some rainwater during the rainy season. If you want to use tap water for maintenance, it is best to let the impurities settle before use.

2. Water level: The water level must be controlled, not too high or too low. Generally, half or 1/3 of the water is enough. Too high a water level will hinder its growth.
