Anyone had experience with 100% coco coir for millipedes?

I wouldn't suggest 100% coir. I use it as less than 1/3 of my mix. There are recipes on this forum or sellers on Etsy where you can buy a good mix. I think the main problem wirh coir is allowing it to dry out. If it is kept moist it should cause a problem. That said, I would add lots of rotting wood and leaves.
