Headed to the hardware store sometime soon to get some more hoses before brewing.
What diameter of hose should I get for use as a blowoff hose with a standard 5 gallon glass carboy? The idea was that it would stick down into the carboy and be airtight. I also have a rubber bung with a grommet (for use with airlock) but it's a pretty small hole.
Am I doing this wrong?
Also first noob question and in b4 RDWHAHB.
