How often should I change the water for hydroponic hyacinth?

1. Frequency of water changes

When doing hydroponics, there is no need to change the water too frequently. Usually, the water can be changed once a week in spring and autumn, and more frequently in summer when the temperature is high, about once every 5 days. Winter is very cold, so the time for changing water can be extended. Generally, the water should be changed every ten days to half a month. Under normal circumstances, if the water level becomes less, you should increase it appropriately.

2. Precautions

1. Water quality: Clean water should be used when changing water, and water with dirt should not be used. If conditions permit, it is recommended to use rainwater or snow water collected on a daily basis. You can also use tap water from your home, but you need to leave it in the water for 1-2 days first.

2. Water level: During the hydroponic process, be careful not to let the water level be too high. Under normal circumstances, the water surface should be about 1-2 cm away from the bottom of the bulb. It cannot exceed the bottom of the bulb. If the water level is too high, it will increase the chance of root rot.

3. Method: When changing the water, do not pour water on the bulb. If there is water on the hyacinth bulb for a long time, it will easily rot.
