Can you grow Paph in hydroponic?

Have you ever thought of growing Paphs in hydroponics without flouting the law of mosquito breeding?
Here it is a plant that has been growing in the same pot for well over 2.5 years in the same old pot. It was grown from a seedling that was given by a friend when he deflasked it. The plant flowered after about 2 years.
This is how the plant is grown:
Growing medium - expanded clay (LECA).
Water level - between 1.5 to cm high.
Fertiliser - weekly at 1/4 strength, flush with water in between.
Note: Not all paph can be grown in this manner. The plant illustrated is a hybrid between concolor and liemianum.
