A rubbermaid tub is not the wisest choice. Just run some mini clotheslines and hang your weed upside down from them.
Do you mean like a dehydrator? Just use a cardboard box instead, cut holes in it and make several levels of flat window screening to lay the stuff on if you've already taken it off the stems and can't hang it to dry any longer.
It's not that there's anything wrong with trying to use a rubbermaid container but number one they are plastic and designed not to let air through, so you'd have to chop it all up and two there are just better uses for those tubs in the pot growing world.
