Another thing to remember is the humidity levels. During this period, dendrobiums do not need a lot of moisture. Very little water will be enough to keep their roots alive. Also keep in mind that their roots constantly need plenty of air circulation so you should place them where there is a lot of fresh air.
Remember, that is based on energy usage, not comfort-levels, which are the purpose of having an air conditioner, in my not-so-humble opinion. Fact: At night, the ideal temperature comfort range for Americans drops to 65 to 72 degrees Fahrenheit (or about 87 degrees if you are my wife).
If you don't have a programmable thermostat, manually adjust the temperature on your air conditioner. While occupying your air conditioned space (at home or at the office), adjust the temperature upward one degree at a time to see what temperature works for you, striving for at least 78 degrees.ost people can live quite comfortably at a temperature of 78Â°F. Rather than reducing your air conditioner's temperature setting to a chilling 72 degrees, try raising it one degree at a time to see how warm it can be before you become uncomfortable.
