You could use it but it's less than ideal for messy stinky wet garter feces. If you want natural substrate, fir bark (reptibark) looks better but still not ideal so I mix it with a fair amount of fine, loose coconut fiber. That helps to absorb those wet stinky feces and it does a pretty good job of controlling odor. The fine coconut fiber makes it easier to spot and clean since wet spots will clump. Don't overcrowd and stay diligent when it comes to keeping it clean since it's just too expensive to change it out completely very often. If it starts smelling like death or urine, change it out completely. I think the hull pieces might be OK but I would mix it with something finer.
From now on, I'll treat others like they treat me. Some will be glad, others should be scared
So if I understand well I'm better to use this (not write on the net, but in the paper catalogue they say it is made of coconut) instead of the coconut husk?
Seems if you buy from a garden store it's cheaper but essentially the same stuff. For some reason they think that if they label it for reptiles, it's worth 3 times as much.
