I want to pick up a Pastel female to breed to my Spider male next year when he is ready. However, I'd like the female I purchase to obviously be older with some weight on her so she will be ready next season as well. I'm trying to save a small amount of cash as opposed to going straight for a proven girl. I know it's difficult to discern weight gains as every snake is different, but does anyone have a range suggestion for what size I should be looking for currently? Thanks!
