Hi there, Newbie to home brewing, where I work there is seemingly an endless supply of 5 gallon buckets that are essentially the same as the ones you get with most home brewing kits, just no holes for airlock/stopper and spigot for bottling. with some modifying could these buckets be used for fermenting/bottling. Lastly, these aren't strictly white buckets, they have some clarity to them, could i paint or wrap them in in a blanket and use them as a primary fermenter with the modification?
