Actully breeding season can be anywhere from Mid November to end of June/July for leopard geckos. It depends on the female. I have no lighting save ambient lights for any of mine.. temps stay the same year round regardless since I use undertank heaters exclusively and I get clutch after clutch out of all my females... up to 9 clutches per female per breeding season while they maintain weight. You need do nothing with leos to get them to breed save give them the right conditions and the right support in the form of heat, humidity and supplemented food. As a matter of fact, just like monitors, when supported correctly, leo's are hard to get to stop breeding rather than difficult to start.
