5 gallon buckets with gamma seal lids are a hell of a lot cheaper. toss a couple 67g 2-way humidity packs in each and you are golden. use some mesh bags used for produce (can get 30-50 for 10$ on amazon) allows you to put more than one strain in a container while also allowing air flow... like cigars in a humidor it is not a problem to do this.. done it for 2 yeas now and there's no cross contamination of flavor or smells.
