That's a sensible and good idea, because anything in the pre-existing environment that's lacking (for the orchid) needs to be compensated for. So using a particular media and applying appropriate amounts of water etc is all part of that.

Pots are popular too. I bought this orchid last year, arrived around late August last year, which had two sheaths. One of them continued to spike and grow buds, which are the biggest ones in the attached photo - taken only about 2 days ago. The other two spikes were small new growths (were not even pseudobulbs - just small pre-bulb growths) in late August last year. This Rlc orchid is growing in scoria. Once a month weak fertiliser (and weak cal-mag application about 2 weeks after each fertiliser application).
