We use pea gravel. Buy it by the scoop... But that is freshly grounded stump material. I also see mold, sap and it getting stuck in my fork.
Pea gravel here is very expensive. I can buy clean crushed rock for about $250 a truck load (~20 yards), pea gravel is over $1,000 and hard to get.
Others have mentioned mold but suggest that drying will avoid that. When I looked at the pine/pine bark mix today it felt dry and there did not seem to be much sap, no residue on my hands and that is normal when I handle green pine lumber. I guess that it does not have much sap since it is produced by peeling the outside of a log prior to milling. Obviously there will be some.
