True. It will be all about 'the system'. If conditions in the system allow undesirable situations to occur or exist - such as a long-term build up of water on certain parts of the plant, followed by cells dying due to cells not getting enough oxygen in that region, or due to certain organisms forming and then thriving in that region ------ then considerations about temperature and air-flow could help bring those situations under control, or even avoid those conditions from occurring.
Obviously, germinated orchid seeds in sterile flasks don't have the fungus and bacteria etc in the flask - assuming successful flasking and assuming maintained sterile conditions.
But for orchids grown outside of the flask - such as in our regular growing areas at home ------ it becomes a consideration.
A consideration of ----- if temperature and humidity and water on the plant (stem, leaves, roots, media and all) ----- then the question - of .... can adequate air-flow be beneficial towards keeping certain unwanted situations under control or avoided? Yes ------ it certainly can. Depends on environment conditions.
Eg. air-movement can help with water movement in the media and along the roots etc. And there are other benefits. Again ----- depends on conditions (humidity, temperature, what nutrients and elements the plant is provided with, and what's in the environment etc).
