Wyeast Budvar 2000

[Mudcrab]

Evening, 

Currently brewing a pilsner using Budvar 2000. I pitched the yeast on Sunday night (after brewing Saturday). The smack pack didn't swell overnight, so I waited another 12 hours before adding it (some 20 hours after the initial smack. 

The yeast isn't too old (late June 16) and I still don't have any action in the airlock. I have my fridge set at 11 degrees and understand activity will lag a little, but I expected it to be bubbling by now. 

A few questions:

Do I need to get some more yeast? 

Is this batch ruined? 

How long can I leave it before adding more yeast?

I may have jumped the gun. Just checked the fermenter and there seems to be a healthy layer of krausen. Still keen to hear anyone's thoughts on my questions. 

Cheers
