Humidor dividers...

[hendu3270]

I have a 300 ct humidor that I bought a couple of months ago when I became so infatuated with cigars, (hello, my name is Chris and I have a problem). Anyway, it was missing one of the dividers in the bottom portion of the humidor, (CI refunded me $10 since it wasn't included). I am wanting to put another divider or maybe even two more. Spanish Cedar is not readilty available in my area and I don't feel like ordering it online and having to wait on it to arrive. My question is this, would it be an issue if I were to simply use a 1/4" thick oak piece as a spacer? I wasn't sure if this would affect my cigars in a bad way, or screw up the humidity level somehow.

I really like the boxes that some of my cigars have come in but trying to keep the boxes in the humidor is just taking uo too much room, so I need to take the gars out of them. Any tips on types of cigars that I could actually have sitting next to other cigars or is the typical rule to have all brands separate from others?

Thanks for any help or advice,

Chris
