Okay I finally tried to commit Hari Kari with my glass carboy and decided plastic bucket fermenter all the way. I am always searching for a great deal and found these VERY inexpensive 6 gallon buckets. So I sent an email regarding their food grade status but I have one of these stores down the street and some $5.00 per bucket is very hard to pass up. Granted construction yellow is not ideal but wow. I may just go get one and see what the codes are on the bottom and see if a gamma seal will fit on them.
