Ball python sexual maturity?

About how long (if eating on a regular basis) will it take for a female to reach 1500g? How about for a male 500g?

Males can be ready at a year and females can be ready at 2 years.

males can go at 6 months if they have some size & are interested,mine were breeding at 8 months old & 550g females can breed at 18 months some do some don't,mine were around 1300g when breeding started & fed good till OV when they OVed they where around 1800g.
