I would suggest two things even though I agree with most of what was said above. I think some people over cool and some people over breed. If you cool (I do) a slight nighttime drop for a couple months is all that's necessary. I like the slight nighttime drop as it seems to improve my breeding. But do what works for you since most homes naturally cool slightly during the winter, even here in Phoenix. Also, there is no need to constantly breed. If I have seen a lock the male gets a rest, he doesn't need to stay in the bin with the female. They do seem to get stressed during breeding so I feel there is no need to add to it for the male or female. I also only feel a need to breed a female once every few weeks. This way I can cycle males and rest animals as much as possible. Just my opinions though, but it works very well for me.
