The foliage and flower-seeking plants used in family water culture flowers are mostly cold-tolerant flowers, and their optimum temperature for growth is generally 18°C ​​to 25°C. Since hydroponic culture only changed its cultivation methods and did not change its growth habits, when the temperature dropped below 10°C, some flowers would grow stagnant and the leaves would lose luster; when the temperature was lower than 5°C, Most of the foliage plants will also be subject to varying degrees of damage, with leaf scorch, old leaves wilting, and even plant death. Therefore, winter caregivers need to take timely conservation measures for hydroponic flowers according to changes in the ambient temperature.
In order to keep warm and cold, you can use discarded foam plastic plates first, cut them according to the size of the hydroponic vessels, splicing and bonding, and wrap the vessels. When the room temperature is lower than 10°C, cover the old newspapers and plastic film on the hydroponic flowers, or increase the water temperature to 18°C ​​to 25°C. This will result in better cold resistance; if your home has a cylinder Tropical fish, then put a shelf at the top of the tank to place the hydroponic flowers on top, which can also play a role in preventing cold.
When the room temperature is lower than 10°C, most hydroponic flowers are in a dormant or semi-dormant state. At this point, the flower hydroponic nutrient solution should be stopped. Only the tap water should be used for conservation. At the same time, the roots of the plants should always be cleaned, and the utensils should be kept clean. . Changing the water is usually 10 days to 15 days. When changing the water, warm water can be properly mixed to keep the water temperature at about 18°C ​​to 25°C. If the water quality is pure and clean, the plants will grow robustly and there will be no rotted roots. Changing the water from 15 days to 20 days or even 30 days will not affect its growth. For those water-cultivated flowers that are still growing slowly, such as kaffir lily, calla lily, etc., a nutrient solution may be applied once every 10 days to 15 days to promote its healthy growth.
In addition, in the selection of hydroponic flowers, flowers that have a wide range of temperature adaptation should be selected as much as possible, such as Monstera, Merlot, Ivy, Raytheon, Anodontina, etc. for hydroponic culture.
