I'm not really panicking, I just want to know whats going on in there. I'm about to remove the blow-off and put in the little airlock, so I'll update if that changes anything (which it shouldn't). It seriously hasn't bubbled for about 24hrs.
Thanks in advance
I'd say you're safe in swapping the blow-off for the airlock. You're probably done with the bulk of the fermentation, but you want to let the yeasts finish their work, as another poster said.
It's not surprising to have different batches perform differently in terms of fermentation times. A lot depends on the yeast, the beer and the temperature (the hotter, the faster). The only surprising thing here is that your previous batch took three days to start. I've never had a batch take more than 36 hours.
