Hard to tell the size based on your description, but it sounds like the oasis would be way too much humidification and could lead to mold, especially if there isn't enough room for the humidified air to spread out

I've shared my secret before, it's worked perfectly for me for many years now in both my cooler and my vino - use twice as many beads as are required and spray the inside of the door/lid whenever it feels like I haven't done it in a while. By doing this I've thrown away all hygrometers and never have humidity issues. It might not work for everybody, but it works perfectly for me and I won't be changing unless I get a humidor big enough to warrant an active system
