Honestly, for storage it probably just comes down to what fits. I store in the bags they recommend, so however many will fit in there, physically is what it would hold….since you’re holding, not drying there’s no risk of overloading and inducing mold growth…Morning
For drying purposes, they say 2.2 pounds wet….which equates to 10-12 zips after drying I think.
For storage, they say it will hold 2-4 pounds (I’ve heard conflicting information on this…)
