Temperature

There are three temperature zones for orchids, and each type of orchid has an ideal temperature zone.

Orchids Need a Temperature Drop at Night

All orchids require lower nighttime temperatures. Some, like Phalaenopsis, need just a 5°F/3°C drop, while others, like Cymbidiums, need as much as 20°F/10°C. These temperature changes allow daily cycles of chemical reactions to happen within the plant.
