I'm a week into my first brew and after reading alot of post on here, I decided to go with a blow-off tube set up during the first week of fermentation. I was planning on not using a secondary and replacing the blow-off with an airlock after the first week for the rest of the time it's in the carboy. Is this necessary? Why couldn't I just leave the blow-off tube/bucket of sanitizer setup on the whole time and not worry about clogged airlocks, explosions, etc.....?? Does it leave to much pressure in the carboy? I dunno....just seems like it'll be less to worry about.....
