I soaked the plant in mild fertilizer water for a few hours and when I looked at it, I could see that there were at least 3 major growing areas joined by old dead pseudobulbs. So I broke it out into three plants. The biggest went into a 4 inch round plastic pot and the other two into 3 inch square plastic pots with the open lattice bottoms, all three with styrofoam at the bottom to allow air to get in. Largest pot all small size orchiata bark, then another with mostly sphagnum and styrofoam and the third in a mix of orchiata and a small amount of sphagnum. So we'll see how it does in all three mixes. Fairly fine roots, not the big cattleya style so I'm guessing at least one of those mixes will work. I'll let you know
And yes, now that it is getting cooler, I'll have them outside during the days but nights in the house, and in house all day when we get into the 40's and 50s.
