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).
Set your water heater to 120ÂºF. Keep the blinds and windows closed during the day and open at night. This is a no-cost way to keep your home a little cooler. Window, ceiling and whole-house fans are also low-cost ways to stay comfortable. Wash clothes in cold water and clean the lint filter in the dryer after every use. Unplug appliances and electronics when not in use. Plug home electronics, such as TVs, DVD players and computers into power strips and turn off the power strips when the equipment is not in use.
