I know of guys using only Boveda in those things. I don't have personal experience but I think it'll be just like any other humidor...a little trial and error and you'll figure out the sweet spot.
They are like a tupperdor on steroids..the concept is the same, it's not a wood box and the seal is extremely fit. I would think Boveda would work great in there, you'll just have to try it and see if what you're planning is enough or not. You can never have too many Boveda.
