Sounds like that spider has a lot of work on his hands. Hope he's UP to the challenge.

My only advice is to check his weight and monitor his condition during the season. Hopefully he eats some mid season meals to help with his production. Don't over work him. Successful breeding it really more about patience and timing than just constant pairing. When she is ready, he needs to be ready, so I would probably do a couple days on and a few days off sort of thing and only increased when I felt follicles. Goodluck
