Phalaenopsis in water culture

[dabblin-n-orchids]

It is true that there are plenty of anaerobic bacteria and fungi that will rot the roots and roots that are not adapted to water will rot in a matter of weeks. But it appears that for some reason a thick layer of algae will prevent the growth of anaerobic bacteria and fungi. and if roots grow into water they grow noticeably differently and are adapted to being completely submerged and it would stand to reason that if you placed them in another media besides water they would die.
