Suggestions as to what to grow two cattleyas in.

[Roly0217]

everybody !!! I'm really excited because I got 2 cattleyas that I had been wanting for a while now. They are Cattleya dowiana aurea and Cattleya iricolor. A grower down here grows all of his dowianas in spaghnum but this is in a greenhouse. He's an orchid scientist and told us that it's the best way to grow them down here in Florida or they tend to die and a friend told me with regards to Cattleya iricolor to mount it. These are both very healthy with new growths starting so the new roots would adjust to the growing medium better. The iricolor in particular has 3 new leads and the dowiana 1. Help anybody !! I don't want to screw this one up. Thank you !!!!
