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).
To test your central air conditioner, you must have the outside temperature above 60 degree Fahrenheit for a period of two days or 48 hours to be precise. Some manufacturers may even recommend a temperature of 65 degrees.This is because turning on the air conditioner at a temperature lower than 60 degrees might actually damage the compressor of the unit. Next you turn the regulator of the fan to 'auto'.ome manufacturers may even recommend a temperature of 65 degrees.
