Right now the plant is in a 4" pot, what size would you recommend going up to? I know some of my other non-orchid plants freak out if they get potted up to large, does it work the same way with oncidiums? And what do you mean by "wash down"? Do you just spray off the plant leaves every day with a little spray bottle of water?
