I used Lutra for the first time last week. I dry pitched and closed the fermenter. At that point, I realized that I needed to retrieve my blowoff tube, as my previous experience with Voss blew all the liquid out of a bubbler.
When I returned and hooked up the blowoff tube connector to the ball lock post, the fermenter depressurized! It was working in 10 minutes!! It just kept accelerating until it ripped through it all in a few days.
