P.regalis mating
From what I have read and watched the inserts are supper fast.
But just to make sure you can put them together once or twice more!
But best of luck with the attempt, that is awesome.
What I have noticed in the hobby, a couple years ago spider wore imported so no big need to breed spiders, so a hand full of people wore breeding spider but it was not nearly as many that are breeding spiders today.
As the imports stop so people started breeding, and over the years it has become much easier to get a successful egg sack with healthy slings out.
So with all the information out there and the slings that will be doing the round, I think you have a good chance to get some ting right.
