How many Boveda do I need?
It’s the capacity of the cigar humidor that determines how many Boveda you use. (In other words, how many cigars the manufacturer said your humidor can hold.)
Here’s a chart to use as a guide. Remember, Boveda will never over-humidify beyond the stated percentage on its respective pack. Using more packs or a larger Boveda than is recommended on the chart is totally fine. Your Boveda will last longer that way.
