As for the number of times you should have it rain, amplexus (when the male gets on top of the female) usually occurs within the first days, but may take a few weeks. As for how long you should have it rain, it's best to do it from 5 to 11 p.m. Your chances of breeding them are best when you place them in the rain chamber every night until they lay eggs (they do lay more than one clutch per season, so keep this in mind). Hope this helps!
