Use one Boveda size 60 pack for every 25 cigars your humidor can hold. If your cigars need a temporary home while you season your humidor, zip them in a plastic bag along with one size 60 Boveda 69% RH pack for every 25 cigars. [4] X Research source

Don’t bother using a hygrometer (an instrument for measuring humidity) while seasoning your humidor. No matter what the reading might say, the advice is the same: wait 14 days. Patience is key!

If you live in a dry climate (or an area with seasonal dryness), season your humidor once or twice a year.

Boveda is safe for stringed instruments and bows. [25] X Research source

If your case has been out in the cold, the packs may harden. Don’t toss them out yet! Let them warm to room temperature then try squeezing them. If the texture is like thick jelly or dense clay, it’s still working![28] X Research source The temperature change won’t impact the effectiveness of the product. [29] X Research source
