Some orchids are exceptionally sensitive to water quality. This sensitivity will effect how the plant grows and blooms. Based on your growing experience, what orchid plants need special water conditions to grow and bloom? As you answer this topic, please keep in mind & let us know where you live and the type of water local to you. Help out the new growers by listing plants and their water requirements based on mineral content, pH level, etc... Do you use RO (reverse osmosis) water? If so, why; further, on which plants?

Cheers!
