I had a strange situation. In my rack i moved across from normal chippings to hemp. after about a week i noticed something out of the corner of my eye as i walked past and there next to the water bowl was a little tiny(very thin) mushroom or toadstool about 1cm high and looked like a cotton bud shape. very odd
I suppose it makes sense with being warm, dark and with the snake splashing tiny amounts of water over the edges but never had them before with chippings
