Cymbidiums in Orchiata advice?

[Paul Mc]

I've been slowly transferring all of my orchids over to Orchiata. I purchased one 40 liter bag of the Classic for my finer root orchids, mini's, Paphs and Phrag and more moisture loving orchids such as Bulbo's and seedlings. Additionally, I bought 2 40 liter bags of the Power+ for the general Phals, Catts, Dendrobiums and Oncidiums. After several days, I am nearly done. Whew, lol...

Now I am questioning what to do with my Cymbidiums. My understanding is that they would prefer a more consistently damp environment, so my first thought would be to use the finer Classic. But my second thought would be over time how would that work out, so should I perhaps mix the larger Power+ with some of the Classic?

My goal in repotting everything is to hopefully avoid the necessity of repotting things ever 6 months to 2 years, depending upon what was used and the type of orchid. I don't mind repotting a few here and there, but would like to try for repotting every 4 to 5 years instead. So keeping that in mind, any additives?
