I just grounded up my castor sacs along with glycerin. Glycerin was used to make it pasty. Some of the castor wasn’t 100% dry, is there a good chance that it will mold in the jars?

you could use methyl parabin as a stabilizer and mold retardant

Wouldnt worry too much about it If your really worried about it, add some vodka or everclear or get some methylparaben. Castor doesnt get too moldy unless it gets rehydrated.

It's fine, just use it.
