I only have raised 1 sulcata. I used coco coir with cypress mulch on top. I never used reptibark. @Tom could answer that.Also I can only fine the coarse type repti bark here in Malaysia, I intend to buy the fine ground repti bark.
Would the coase type repti bark suffice?
I am just concern on the poor crawling ability of my baby sulcata once he is on a uneven and loose terrain. ?
