I see, you might want to join this group on facebook for more answers, if you don't get many answers here? The group is called "Green Tree Pythons~ Buy,Sell,Trade & Chat", and you can find it just by searching "green tree pythons" in groups.
There are a lot of nice breeders there who no doubt have experience with farm bred. And I find that group more active with replies and discussion than the other green tree python groups on facebook. I've asked questions about farm bred/wild caught there before and it was pretty helpful.
