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).
Donât set your thermostat at a colder setting than normal when you turn your air conditioner on. It will not cool the room any faster, but it will use more energy. Use a ceiling fan in conjunction with your air conditioner to spread cooled air to other rooms. Clean or replace air conditioning filters monthly.
