Rather than collecting those little packets, you can get a tub of silica at most dollar stores, the equivalent of several dozen packets. Then replace with a new tub every few months.
You don't need to replace. silica gel is easily dried out in an oven or even a microwave.

The tubs collect a huge amount of moisture and trap it before they are exhausted. They work splendidly and last for months. But you have to make sure the plastic boxes are air tight. Most of them are not, just made for clothes storage in closets, etc.

Very true about 'air tight' the better ones lock on all 4 of the top edges. I have things I need to keep moist and things I need to keep dry. The airtight containers work great in both uses.

Exactly what I do. I use one of the stamped metal ones, not the big combination lock safes. More on that later.
Use some stick on window weatherstripping on he door to make the box fairly tight. I got at a sporting goods store a plastic box thing made for this purpose. It holds silica gel, and can be plugged in to a wall outlet when it gets saturated. There are little indicator beads on the front. Usually takes overnight to recharge. Never any fungus.
The big combination lock safes are fire safes. Something that you never want. A fire safe is lined with some kind of particle board that absorbs humidity out of the air. When there's a fire, this moisture saturates the contents and delays ignition.
It also saves moisture. it will al all things do, equalize the level of humidity inside the closed box. So the fire safes are a wasted effort.
