Yea NERD says they get 12-14 feet on average but its all in the genetics of the snake. What are you going to do if your retic gets 20+ feet?

All im saying is prepare for a very large snake but hope for a 12-14 FT snake.

And when you said you had a 5 year old retic just over 13 feet you were making it sound like that is what you want to do with your snake. And "maintaining" a snakes growth so it stays small is just wrong. With all the different species of snake out there why would you "stunt" a snakes growth
