Back in about 2010, I got a freebie desktop and "seasoned" it by wiping it down with a wet rag. Figured, "if a little's good, more is better" and I left the wet rag in there for a few days. No visible mold. Super accurate brasstic dial hygrometer reads 73 ish, so I figure I'm ready to drop my bundles of Famous Nics and Flor De Olivas in there and they'll be good to go. A week later, the whole left side of the humi (and sticks) are fuzzy. I realized I was in over my head. ...That's what steered me to this great community.
