Almost anything but MG---notoriously not consistent. Any "hot" (poop)material should be aged first for potting, but rabbit is good for outdoor planting in moderation fairly fresh. Check the PH of your mix before using it.
Agree there, but tbh I can't complain too much about MG. Had good results using the potting mix for my 1st ever grow this year. Just looking to get more organic and more hands on for my new plants.
