how long does it takes for a GTP to mature?

[Ah_dex]

hi, people... can anyone kindly tell me how long does it take for a green tree python to mature?

[snakeylesnake]

usually anywhere between three - four years. weight is also a factor, females should be at least 1000g. basically it the bigger the better for females (not obese) and males should also not be to fat!
my female is currently 4.5 yrs old, weighs 1400g and about 5ft long, whereas my male at the same age is 900g and roughly 4ft.
cheers
