What is the most suitable temperature and humidity for the orchid?
The suitable temperature for the growth of Cymbidium in winter is 15 ℃ 20 ℃, and it is better not lower than 10 mol. The temperature should be kept at about 18 ℃ after scurrying, and the temperature difference between day and night should be about 10 ℃, otherwise the flower arrow will blossom if it does not reach a proper height, and it is easy to form a "sandwiched arrow". The magnolia should be moved indoors when the outdoor temperature is lower than 10 ℃ at night. When the indoor temperature is lower than 10 ℃, in addition to covering the surface of the basin soil with a layer of 1 cm thick charcoal powder, the flowerpot should also be placed in the indoor sunny warm place. When the indoor temperature is very low, cover the film on the flowerpot to raise temperature, but the temperature in the cover should not exceed 25 ℃, if it exceeds, it should be ventilated and cooled in time.
