How to regulate temperature? Mastering these methods is very important

The purpose of regulating or controlling temperature is to giveorchidsa suitable temperature so they can grow normally and thrive with abundant flowers and lush foliage. The main means are protecting against cold in winter and against heat in summer. Regulating temperature can hasten or delay the flowering period; temperature has a clear effect on the flowering period. Indoors in Beijing, the springorchidflowering period can be as much as 20-35 days earlier than in the wild. Conversely, lowering the temperature can delay flowering. The way to regulate temperature is to build greenhouses and orchid sheds. In addition, trees, shrubs, vines and lawns can be planted in or beside theorchidgrowing area to regulate temperature. Shade from trees can block sunlight and reduce the radiant heat of the sun. Tree shade moves as the earth turns, so it can regulate naturally. In summer, strengthening ventilation to keep the air moving, opening doors and windows, or using an electric fan to blow air can also lower the temperature. Conversely, in winter, blocking the wind, removing shade materials and exposing the plants to more sunlight can also keep them warm. It should be noted that one must pay attention not only to air temperature but also to the temperature of the potting soil. Generally, potting soil temperature changes as air temperature rises and falls, but its change is relatively slow. Orchid potting soil must never be exposed to the scorching sun; when watering, the water temperature must not differ too greatly from the soil temperature. (Song Shi)
