I think I'm going to try the RHPs soon. I have flexwatt on the boaphiles and not real happy with it. I like my substrate to be thicker with my boas. The heat coming from above would be better I think.
As of right now the ambient temps are good, I'm worried about this winter. I really don't want to add another space heater in the room.

Thanks for the link Gio. Have you found any in the deep blue?
