Things You'll Need
Instructions
Decide how big you want the humidor to be. Stay small if you only have a few cigars. However, if you buy several boxes at once, you may need a larger one.
Keep your focus on the money. You want to build a cheap humidor, so you need to think outside the box.
Pick up a Tupperware container or plastic ice chest the size you need. This is a different way of thinking, but it is cheap, particularly if you have one lying around.
Set your cigars into the container. Keep them in a cigar box as the plastic might make them sweat if it comes into contact with them.
Purchase a small hygrometer and place it inside the container to measure the humidity level at all times. Keep an eye on it so that you don't have too much moisture building up.
Place the lid on the container and "burp" it if necessary to ensure it is airtight. If using a Tupperware container, open it once a week, because Tupperware actually keeps too much air out.
