First of all, we should have a simple understanding of it: it has a strong ability to resist the cold, the most suitable temperature is 16 to 20 degrees, if the temperature drops to - 4 degrees, it will frostbite the plant, and its leaves will become dull.
In winter, the interval of water exchange can be extended. Generally, 10 to 15 days in spring and autumn, and 20 days in winter.
When changing water, you'd better put it in the sunshine for half a day first. If there is no sunshine, you should put it for one to two days. But if pure water is chosen, it can be used directly. But the winter temperature is lower, so no matter what kind of water, the water temperature should be equal to or not much different from the original water temperature in the utensils, then the water can be changed, which is conducive to the health of plants.
When changing the water, observe the root. If there are other foreign matters covered, wash the root with clean water and put it back in the vessel. If there is any necrotic root, trim it when changing the water.
Winter hydroponics, the amount of water should not be too much, the height of water can completely soak the whole root in it.
If the temperature drops to 10 degrees in winter, the concentration of nutrient solution should be reduced to 1 /2 or 1 /3 of the normal level, or even the application can be suspended.
Temperature control in winter plays an important role in the growth and health of plants, so we must pay attention to keep it!
