Hello Tennessee. Congrats on the Wine-O !
I say go for it. Just remember the cigars will hold RH as well. The point being: Don't panic when you first load the wineador. You like 64% and that's where I like it too. The RH you may see go up after loading and stabilize a little high. Mine went to 72% and slowly dropped down over a few days. Silica KL will pull everything down to 65%RH. Spritz nothing more till you see where it lands loaded.
Cigars hold RH as well. So once you are stacked and stabilized, you won't fluctuate as much when you introduce additional stock in the future.
