De ja vu!
I cool during june,july,august.
I introduce them during july,august,september.
Once mating has been observed I continue introducing the male on and off again untill no further interest is shown.This I feel is to ensure a viable clutch.I have a time table that I drew up in one of my record keeping books that I try to stick to.I'll post it here and hopefully it may help a few members that are new to breeding.

PS
This is generally a basic schedule that I have used (to give you a rough idea).I will often make changes in temps or daylight hours etc depending on the situation.Once females are gravid you may wish to raise temps to 32* (personal choice)
