What is the proper humidity level?Updated a year ago

The bag being a vapor barrier, isolates the inside humidity from the outside humidity. This usually handles all of your humidity needs. During colonization you have nothing to worry about.

Once you're ready for fruiting conditions you will want to introduce fresh air exchange:

Even after this we generally do not have to worry about humidity. However some people, in dry climates, may experience the need for misting. You will know this by the level of condensation on the side walls of the bag. If there is none, we recommend misting with a fine mist sprayer and distilled water. 

If there is condensation on the side of the bag you will generally not need misting. Most people will not require it, this is why we omit it from our instructional videos.
