Air lock or blow off tube

[cucci28]

Is it necessary to switch from a blow off tube to an airlock during the fermentation process? Or can I just leave my blow off tube on the whole time?

You can just leave it the blow off tube on, no problem with that.

I only switch to an airlock if I need the blow off tube for another batch.

I always use a blowoff in my fermentation chamber during primary fermentation. The only time I switch to an airlock is when i move to long term aging for things like sours, ciders or meads.

Leave the blow-off tube. Just remember it if you cold crash.

Not that I've forgotten, or anything...
