The temperature conditions required for safe wintering of flowers under hydroponic conditions are consistent with the temperatures required for soil cultivation. Hydroponic flowers are not tolerant to cold flowers, and the optimum temperature for growth is generally 18°C-25°C. When the temperature drops below 10°C, some flowers grow stagnant and the leaf color loses luster; below 5°C, most foliage plants suffer Different degrees of injury - leaf scorch, old leaves yellow, wilt off, and even death. In the absence of facilities and capabilities to adjust the ambient temperature, it may be appropriate to choose flowers that have a wider range of temperature adaptations, such as Monstera, Calla Lily, Ivy, Tiger-limited Evergreen, and Clivia. In addition, discarded foam boards can be used, cut to size according to the dimensions of the hydroponic vessels, and then spliced ​​and glued to wrap the vessels. When the room temperature is lower than 10°C, cover old newspapers, plastic films, or increase the water temperature to 18°C ​​or 25°C. Most of the hydroponic flowers are dormant or semi-dormant when the room temperature is below 10°C in winter. At this point should stop the application of flower hydroponic nutrient solution, only with tap water, and on time change the water (change the water temperature is maintained at about 18 ~ 25 °C), clean the plant's roots, keep utensils clean. Usually 10 to 15 days to replace a new water, if the water is pure and clean, the plants grow strong, no rot, 15 to 20 days and even 30 days to replace once 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 can be applied once every 10-15 days to promote its healthy growth.
