Keeping snakes without a hotspot

[BillyCostume]

I was recently speaking to a local breeder( a well known and respected one at that) and he was telling me how he keeps his entire collection at a constant temperature without offering the opportunity for the animals to thermo regulate. I was curious as to what everyone thinks of this. I wonder how this affects the animals long term??. I personally feel uncomfortable not letting my snakes cool off and warm up as wanted. Btw he breeds various boas and pythons
