Beyond peat/mulch

I have been searching for that perfect substrate for a while to put in my BP snake rack. I have used unprinted news paper and liked it but it did not do well with humidity. I moved to coconut husk fiber (bricks) and it did well as long as I allow it to dry out after letting it expand. I do like it but I find it too fine and if I spill the water dish while closing or opening their tubs, the stays too humid for days.

I was doing a lot of research and came across an item called Beyond Peat and Beyond Mulch. I was hoping someone had experience with it and could tell me what it is like? Sounds like it is a bit chunkier then coconut husk and seems to be safe for my BPs. Does anyone know?

I do not know about the "beyond" beddings, but I have had good luck with recycled newspaper pellet bedding (Good Mews), though I just switched back to regular old newspaper because I get it for free. I was very happy with how the recycled newspaper pellets always kept the humidity about right.
