Soil mix for a planted millipede tank?

[Cavedweller]

I'm not sure if this is the correct section for this thread, but the site seemed primarily aquarium-oriented, so I wasn't sure of this should go to the Substrate section. I still consider myself a complete newbie to this site, so please correct any faux pas on my part.

I made this post regarding millipede tank drainage layers nearly a year and a half ago. Sadly, my grand plans for a terrarium were put on hold due to having a an barely-insulated apartment with a mold infestation in the walls. However, I am now out of the moldy, 85 degree deathbox, and can resume my quest for a millipede terrarium.

To summarize the progress made in the previous post I made, I plan to house Dendrostreptus macracanthus, possibly some Macrolenostreptus brachycerus, and the usual pillbugs in a planted 10 gal.

The temperature will be around 75F, and the humidity at 60-70%. For plants I'm thinking a small ficus, creeping fig or pothos, pilea, and mosses.

Now for the question:

What kind of soil mix should I be using for this tank? Coco fiber is pretty standard for millipedes as far as I know, but I assume the plants won't like it without something else added.

You can use an abg mix, either store bought or make you own. There are recipes out there for it. Personally, i like the soiless hydroponics growing substrates. I really don't know much about millipedes, so i am not positive they will be the best for them. I just know plants love'em.....lol i would suggest checking out one of the herp forums, they normally have good bug sections with very knowledgeable people

Hydrophyte suggested this rainforest mix soil. I looked into some ABG mixes too, and wasn't sure about the addition of charcoal. I wasn't sure how good that would be for 'pedes, but apparently it's fine for terrestrial isopods, who pretty much have the same diet and requirements.

I don't imagine soilless substrates would work well for millipdes, considering they live in/eat soil.

I'll go check out the herp section more carefully for bug info, thanks!

What does ABG stand for, anyway?
