Paphs grow in areas which are influenced by the southwest and northeast monsoons, the phenomena that determines the basic weather patterns in Asia. The southwest monsoon usually begins in April, at which time the prevailing wind is blowing from the southwest from India to Japan, picking up heavy moisture from the equatorial belt, sweeping it to the northeast and dumping copious amounts of moisture throughout the entire region. During the southwest monsoon the areas under its influence experience daily heavy rainfall on a schedule so reliable you could almost set your clock by the beginning and ending of the rain. Buy September or October the monsoon winds turn around 180 degrees and become what is called the northeast monsoon, bringing cooler and dryer air from the arctic regions down over the monsoon belt. There is virtually no rain throughout the northeast monsoon between October and March.
Humidity is low, temperatures are much lower and nights are cooler.
I have broken down the paph species into five groups and have listed culture conditions for each group. Keep in mind that both parents will be reflected in the genes of the hybrid plant, but the pod parent should exert the strongest influence. If I have made any errors or omissions in this list I would appreciate being informed about them. Also, if you have any differing opinions I would like to hear from you. I hope the above helps you to grow and bloom bigger and better Paphs.
