2.5 gallon brew in 6.5gallon bucket- Will I need a blow off tube?

[peroua15]

I recently brewed a strong belgian and was wondering, for safety and cleanliness reasons, if a blow off tube would be necessary. its going to be a strong beer and sit in the bucket for a while. i just don't want the top to possibly blow off and deal with that when I could have easily prevented that? i doubt that that much foam would occur, but wondering if anyone has had that happen before on a smaller batch...?

I have done a few small batches similar like what you are doing with out the need for a blow off. The latest was a 3.5 gallon stout (1.076 sg) in a 5 gallon primary this one never got close to needing a blow off.

You will not even be at half the capacity of your FV, so you should not need a blowoff due to all the headspace. If you were at 4-4.5 gallons with a high gravity recipe, then one may be needed.
