Default time for blow off tube?

...or rather not?

the beer is fermenting for 48 hours now, I used us-05 yeast, OG was 1.050, fermentation temperature is around 64 F. I have slower airlock activity for last couple of hours, but still.....

any advice?

Brew me a river...

If it doesn't blow off in the first 48 hours of active fermenting, it probably isn't going to. You'll probably be fine here without one.

I generally start my beers with a large blowoff tube "just in case" and switch to an airlock after high krausen.
