So i think i have a solid mixture that helps with humidity, maintaining burrows, and wont create excess moisture at the very bottom. 1part forest floor, 2part peat moss, 2part eco earth, and lastly .75part playsand. I'm currently testing it with our Pixie Frog Koopa and its holding up very well, its allowing those air pockets needed for the spring tails and isopods to breed and feed off the leaf litter thats mixed in. I also have some Discoids in the mix of it all to help with the aeration of the soil and provide Koopa that instinct of allowing him to "hunt" when they crawl by. I have nightcrawlers also on their way that I'll add as well. I think this is going to work beautifully for Daenerys!
