I am considering getting a Rouge kit from AHS and use their pacman yeast. Consider all the tales on this site about using blowoff tubes, I have been thinking how I can set that up for myself. I have a 6 gallon plastic fermenter with a 1" drilled hold in the lid. How can I install a 1" blowoff tube with that? It seems I would have to enlarge that hole, but maybe others have come up with a different way. Thanks for any input.
