I picked up 4 of these;

carboys for free today and am trying to think of how i can use them as beer fermentors.

Is polypropalene ok to brew beer in??

It has a screw top. Should I drill a hole in the screw top and then fit a blow off tube into the hole,silicon seal it and be good to go?

Should I buy a #13 1/2 stopper and drill a hole in if for a airlock?

Should I use it as a primarly or secondary? I have only one glass 6.5 carboy of my own other then these.



I really appreciate any words of advice from those out there in the know.
