humidity in an incubator

i dont know if this should be here or in the breeding section, but if i am building my own incubator out of a mini fridge what would be the best way to hold humidity ive heard of misting but im not completely sure. thanks in advance

It's not about the humidity in the incubator but the humidity in the egg boxes.

Proper humidity is by providing the proper medium in each individual egg box, once you have the proper medium you should not have to add water and there shouldn't be anything for you to do during the time of incubation except airing out every other day about 2 weeks before hatching time.

For proper humidity I use this setup

7 quarts tub, light diffuser, 4 cups of vermiculite, 2 cups of water

thank you i was confused about it because it didnt make sense to have the whole fridge like that

But it is a good idea to put (sealed) bottles of water in there, as many as you can fit without disrupting air circulation. They'll act as a heat sink if you get a temp spike, an insulator to help reduce power demands on your heat supply, and as a radiant source to hold temps up in a power failure.

Yeah deff be more worried for humidity inside the egg box. We mix 1:1 ratio by weight of vermiculite and water. Usually 250 grams to 250 grams. Never have a problem with that. They get enough air flow from me opening the tub every other day in anxiety!
