what is APS? all purpose soil?
Should i substitute lava rocks for sphagnum? I have also seen turface and wonder about it. Most of my pings look incredible in my soil mixture but I do have a few that don't seem to do as well. I cannot tell if they like the soil drier or it just needs different light.
For a terrarium, is my mixture of 1:1:1 of sphagnum, sand, and pumice good? Is there a better mixture? Thanks for the help!
