Needing more storage I'm looking at using an ice chest. It will likely be some time before I'd be at capacity, but I'm wondering if having too much empty space is a bad thing.

I have one ice chest I could sacrifice for storage but it's ~28 qts. Is that a bit much for say 2 boxes? I've eyed an ice chest that would be hard pressed to hold a 12 pack that seems about the right size.

I'm guessing a larger volume container would just need more Humidification?
