I just started my first brew. I’m using the deluxe starter (glass Carboys) and I’ve run into blowoff in less than 24 hours. Are you supposed to keep the red plastic cap on the Airlock or not? I had it on. Your instructional DVD shows an airlock with a clear cap. In some shots it looks like the cap is on, but then you had a close up shot of the airlock with the cap off. The cap does not appear to have any ventilation holes in it to allow gas to escape.
