I made a another mini bubbleponics setup out of a large I Can't Believe It's Not Butter container with a 3" netpot in the lid. Can't wait to throw one of my little seedlings in it. Anyway, I spraypainted the outside with 2 coats of black then two coats of white and there is some overspray inside the container. Its been dry for like 1.5 weeks now. Should I leave it or clean it out? If so, what would be the easiest way? Thanks!
