best substrate for a shroom box

[ChadmRoman]

Hi All, Currently building a shroom 11 gallon cube, wondering the best substrate to use. I was thinking of crushing rock into small pieces as the substrate so as the shrooms split and attach to another rock, sell off that shroom. Looking for other ideas before I finalize this little project.

Thank you in advance.

Florida Crushed coral could work. You can also buy rubble rock

that def could work and I like the size. Will check locally here in CA if any LFS carry. Thank you very much...

When I was selling corals out of my 2 bedroom appartment I had a 10 gallon tank for mushrooms and one for ricordia and I ran crushed coral or Aruba Puka Shells for substrate to make mounting on rock rubble much easier! I used just enough to keep them from attaching to the glass bottom of the tank so it was a pretty shallow sand bed.

You could also add biomedia like seachem matrix. Its basically just pumice stone that has quality control and is clean.
