I only bred two males to one female last year - so I probably don't have the best breeding advice - it was mostly just an experiment that ended up being a wonderful experience.
As I said I didn't change anything by way of temps, lighting or feeding. The one older male had started refusing some feedings but the female and younger male continued eating every week like always and then the female stopped eating and I assumed that it took. I honestly had no clue as to if she would become gravid or even ovulate - until I saw her do it. It seemed like everyone kept saying how hard it was and how everything had to be so perfect - and since it was sooo not that way for me - I'd assumed it wasn't going to work.
I would think that if you are planning on breeding them - then the optimal way to do it would be to include the temp drop and the adjust their lighting. After all that seems to be what works best for those that have been doing it for much longer than I have.
Sorry I don't have any better advice.
