New P. Taida Salu 'Sunset" in NZ Spag, repot?

[jkrobins]

I recently purchased a beautiful P Taida Salu 'Sunset' from a reputable local grower (he was not around when I got the plant so I had no conversation with him.) When I got home I discovered that the plant was planted in NZ Spag. I is a well grown plant with two flower spikes with many blooms and buds. I love it but I am not happy about the spag. Two problems: 1 - all my other orchids are planted in the same bark, spag, perlite mix that I have been using for 20 years and they respond well to my 5 to 7 day watering schedule. (One time I water in the sink and fertalize while they are still damp, the next time I water in situ with no fertalizer.) A culture sheet was sent with the plant and it said to water lightly once a week and do not over water. I already water a couple of plants (Zygos and a Phrag) more often and hate to have to come up with a third schedule. 2 - I am not really in favor of using spahgnum moss for horticulture as the bogs world wide are being depleted. Bark is a renewable resource. So, will I lose these lovely blooms if I repot now or should I hope that I don't drown or starve the plant in I wait?
