First lambic - what to expect in fermentation

Greetings,

I started my first lambic -  the Brewing Classic Style recipe.
I intially pitched S-05 and then when krausen fell, I pitched 2 bottles of ECY BugFarm. I did not make a starter of the Bugfarm.

So what should I expect to see in terms of fermentation activity?  Is this a subtle process or should I be seeing air lock activity, etc?

I know this is a year+ brew, but curious on what visible indicators of progress I can expect short  term.

Regards,

It is much more subtle than your typical fermentation.  You might see some airlock activity once the new microbes adapt to their new environment.  I would not be worried if you don’t see any airlock activity.  I did something like what you did with a Flanders Red but with the WYeast Lambic Blend.  I did not use an airlock though, just a carboy cap loosely attached.  I wanted oxygen to slowly seep into beer to mimic barrel fermentation.
