Safe store bought soil brands for millipedes

[kjgalaxy]

My current tank of millies has gotten roaches in it and I'm setting up a new tank for my guys with a better sealed screen lid. I'm trying to find safe store bought soil (in the United States) for my tank rebuild. I have found some "Jiffy" Natural and organic Seed starting mix. It says it contains "50-60% sphagnum peat moss, vermiculite, coir pith, and lime for PH balance." Is the vermiculite and lime safe for the millies? I have heard mixed comments on coconut fiber but read that so long as it's not more than 30 to 50% it's okay, so long as the rest is edibles for the millies. I've got some millie soil I have bought from sellers, some decaying white wood, and some leaves to mix in and well as cuttle bone. I'm not new to millies but trying to set up a completely new tank in one fell swoop and finding proper soil of the quantity I need it is a bit more difficult. Leaves have become harder to come by in the quantity I need (at a reasonable price). I'm getting ready to ferment some oak wood pellets, but that'll take a month, and I have a couple oak branches I found that I will cut up a bit and bake. Appreciate any guidance on finding safe store bought soil.

Don't know if it's available in the States but I've used Levingtons Natural Organic Top Soil.
If you cannot find that any Natural Organic top soil will be good.
No additives, not made with manure, Levingtons even state that if it's to be used for plants fertilizer will have to be added.
Make sure it's Naturally organic, then mix with your hardwood and leaves.
