Using Orchiata for Phalenopsis violacea Hybrid

[psoque]

Hi. I just re-potted my first Phalaenopsis violacea hybrid. It came with a lot of nice roots all coiled in a knot around a tight plug of sphagnum moss. When I took out the plant and removed the moss, I was pleasantly surprised to see that all roots were doing well. I guess the commercial grower really knows what they are doing.

Anyways, I wanted to re-pot into a medium that would last longer, so I decided to pot in this mix in a 4 inch Aircone

-volcanic rock and charcoal bottom layer
-mixture of 1:10 sphagnum moss: standard sized Orchiata
-a few sprinkling of diatomite pebbles and sphagnum moss on top

Hopefully this would be humid enough of a mixture for this plant.

Do you think I should have added more sphagnum moss in the mixture?

Also, what is the point of using Orchiata if sphagnum part would most likely last much shorter than Orchiata, meaning that I would be wasting the Orchiata?

Thanks.
