So I'm sitting at my desk at work and I just realized that I didn't put water in the airlock of my first brew (yeast pitched ~2:00 Saturday). Are there potential problems from this? Should I run home (love the flextime!) and put water in it? I looked last night (got home at 1 AM from doing taxes at my parent's) and there was condensation in the airlock but it didn't dawn on me until about 2 minutes ago that I'd messed up.
