Need input from all of you with racks. I just came from a site Exotic Nature.com and they have step by step instrucions on a rack. These racks are the same style as freedom breeder they are framed not enclosed and have screen top. what do you all think of this type of cage over the regular racks like malamine and the plastics which totally enclose the tubs? What are the pros and cons? The reason I ask is because with these instructions this rack is easy to make but at the same time my snakes are in a basement room heated by portable heater, in the winter this room can get as low as 60 even with the heater. Im wondering if the open style rack can hold in heat
