Sulcactas generally reach sexual maturity anywhere from 7 years on...a lot has to do with size. Once they hit 15" or so, generally, they're ready-to-go!
Generally females are sexually mature at 16", although occasionally they reproduce a little smaller than that. Males generally at 14". So a 13-14" female would be a sub-adult.
I never had exact numbers for this, but I really like Kristina's time tables there, so I think I'll stick to that from now on.
