I haven't seen a single bubble...
I have several varieties of yeast cultures on slants which I propagate into a large enough volume to pitch for my brews. This particular time I used London Ale WLP013 that had been slanted for 9 months, definitely pushing the boundaries from what I've read/heard. After 24 hours and zero activity I decided to quickly make up a starter of Irish Ale WLP004 (much newer slant) and pitch that. It was a quick step-up - around 24 hours from slant to 1 cup to 1 pint to pitch, and the foam began to build and pretty soon we're at high krausen. I haven't seen a single bubble out of my airlock. I've read a hundred times not to judge the fermentation process by the airlock, but I've always seen bubbles.
Now, of course I had changed something - I replaced my drilled rubber stopper that goes in my 6.5 gallon carboy with the purple cap. It is a snug fit, and I assume it is air tight.
Has anyone ever not seen a single bubble while the fermentation process is going on?
Has anyone used the purple cap for their 6.5 gallon carboy and had a problem?
I'm kinda stumped, let me know what you guys think - leak in the cap is the only explanation I can come up with, but it doesn't seem likely given how well the cap fits.
