The temperature required for the cultivation of orchids

Generally speaking, the relative humidity of 50% to 70% is suitable for the cultivation of Cymbidium. Conditional greenhouse, can use atomizer or automatic sprinkler and other devices often maintain the appropriate humidity. Greenhouses without conditions can only rely on capacity watering to maintain humidity. Terrestrial orchids need more water, the general standard is not dry, once dry should be immediately watered. The amount of water used for watering epiphytic orchids; limited to the ability to moisten the roots exposed in the air. Under the natural conditions of origin, epiphytic orchid can achieve normal water absorption with the help of fog, night dew, Rain Water and so on. When Wandai orchid is planted in a frame basin, it is necessary to increase the watering times because the roots are exposed to the air, in order to prolong the water absorption time, otherwise it will affect the normal growth and development.
