Points well taken and thanks! I think I'll just run the AC in the room to get the Bar Necks into the very low 70s..fortunately I have radiant panels to govern all those in the room that don't need to be cooled (Boiga, Gonyosoma). I still need to contend w/the Sanzinia as they require a much cooler cycle than would be healthy for the Bar Necks. David Means got 3 nice clutches from his Bar Necks this year and only allowed them to drop to 70F..maybe 68F at the lowest. Fortunately I have enough time to figure this all out.
