Hi everyone, Humphrey’s an 8 month old Hermann’s tort so he’s still really small, I want him to start playing outside more in a space where he’ll be safe and won’t get lost. I got him an outdoor playpen and I wanted to fill it with soil or dirt of some sort, I read that plain garden soil with no additives or fertilizer could work but does anyone know any good brands? Most garden soils have perlite or some sort of additive so yeah pls let me know if anyone knows a good brand!
