Here is one more thing to help out you folks that may be trying things out, liking them, and deciding “hey, I need a humidor”.
Build a coolidor. Skip the cheap wood humidors, they dont work for shit.
Go to Walmart(or wherever coolers are sold). Get you a cooler of a size you think will work for you, buy larger than you think you need. Ive got a 150qt because I buy cigars by the box. It would also double as a cooler for dead bodies in a pinch! Bring your cooler home and stuff it full of newspapers for 2-3 days. This will absorb the plastic smell that the cooler has. Also while at Walmart get a gallon if distilled water and a spray bottle(might have to head to HomoDepot to get the spray bottle).
Head on over to Petsmart and over to the cat litter section. What you are looking for is exquisicat silica UNSCENTED cat litter such as this:

Then head on over to the fish filter section and get you some filter bags for 89c.

What you have just created is the same thing as a “cigar specific” silica gel bead product that costs ~$30 a pound. You just made 8lbs for ~15 bucks.
I have 2 of the big fish filter bags(about 1 or 1.25lbs a piece) in my 150qt cooler and its plenty. 1 small bag(there are two sizes of the fish filters) will do about 1/2 lb. large bag is about 1lb. 1 large bag per 75qt is about right. So 1 small bag would work up to about 37.5qt or there abouts. Not a problem to have a little to much.
The silica gel cat litter will keep your coolidor at right around 65% RH. Mine has been setup for almost 5 years and it sits rock solid at 65%. Want to know WHY the cat litter holds 65%? Because engineers figured out that the smell of cat piss is held in if you can keep it around 65% RH. Kinda gross, but it works for our purposes.
The other thing you will want is a digital Hygrometer thats adjustable. Lots of these on the market around ~25 bucks. I have the Hygroset. Xikar makes one. Probably a few others. You will want to salt calibrate it before throwing it in your humidor. Take a clean dry milk jug lid, fill it with salt, put some of your distilled water on it(wet the salt, but dont drown it, just saturated) then take that lid plus your hygrometer and put it in a zip lock bag. After at least 24 hours if not 48 hours your hygrometer should read 70%. IF it doesnt, adjust it. Mine has a knob and each click is 1%. Mine has sat rock solid after its initial adjustment for almost 5 years, even through a battery change. I test it yearly.
I watch mine and typically in the summer spray distilled water on the bag/s once a month(air is more humid generally) and in the winter I have to spray water typically weekly.
Thats about a 2 year old picture of my setup.
