Sulcata growth, 4 years

[Rex1718]

I know it’s hard to pin point a growth rate for a sulcata. I feel like my sulcata Rex is on the smaller end of the spectrum. He was hatched in a dry environment and first couple months kept at out dated standards. Will that effect his growth rate for life?
This is him the 4 years I’ve had him.

Very nice looking Tortoise, it's hard to believe that they can grow so fast. My Sammy boy just turned 3 on Dec 21. weighing 24 pound/6ozs. On Newyears day he weighed 25 pound/2ozs. Keep up the good work.
