Quick and easy question here I hope!
Does my secondary need to be the same size as my primary? or if I used say a 6.5G carboy primary but plan on using a 5G secondary? I presume since the most active fermentation is done this would be ok? or do i need to use a 6 or 6.5G for a secondary as well?
(Just trying to figure out my logistics as I start my next brew)
