3) Calibrate your digital hygrometer using the salt method or a Boveda test kit.
4) Order some beads for humidification-HeartfeltIndustries and Shilala's beads are what most use here. Beads will regulate your humidity by absorbing moisture when it is too high and releasing it when it is too low. You can also use the green sponge with Propylene Glycol solution, but it is a bit messier than beads.
