i found a used glass carboy at an ongoing flea market. the stuff they sell is used, usually taken out of houses they clean when an old peron with no next of kin kicks the keg. anyway they had a large glass jug that was probably around 7-8 gallons for sale for 10 bucks. the bottom was frosted and had "1977" cast into it. it was about 1/4 full of potting soil and had a dead plant in it. would it be worth my while to grab it and clean it out? I want to buy a secondary fermentor to larer in but have not yet shopped arround.
