Sounds like you are taking good care of them. Air movement is very important and you seem to have that down. In the winter, when temps drop, that will signal the Phal to begin a spike. I would not worry about the heat right now. I have several Phals outside in the shade and it is getting around 95 here with heat index up to 107. Actually, they are growing more since they left the AC at 73 degrees.

My Oncidiums are also outside with morning sun/afternoon shade and they are doing well. I believe your Odonto likes similar conditions, but someone else more experienced than I am will have to chime in.
