I'm by no means an expert and just had my first attempt at breeding last season. I followed the instructions on 8ball's website at first but the realized that barometric pressure has more effect on breeding behavior than the temps themselves, my female laid 8 healthy eggs with a 100% hatch rate.
This year i have not lowered any temps but living in new england the ambient temps are naturally lower than in in the summer.
So the cool side is cooler than usual but the hot spots are the same as always. With that said i just placed my pastel male with my spider female and in about a day found them locked up (both were virgins) the one thing i know for a fact that helps them get going is to mist the cages and snakes with water when you place the male in with the female and then at least once a day for the time you keep them together. This and when it either rains or snows pretty much always gets them locking up or at least trying to.
Good luck to everyone this season.
