coolmist humidifiers should I even bother?

A good humidity meter is an asset.
That way you know what the conditions are in every corner of your growing area - and they DO change!!
Without a lot of effort, I can't keep my humidity over 50% in the winter. Summer is easy, but the dry, cold air is a problem. I use a large mister/fogger that is capable of putting up to 0.5 gal. of water into the air every hour and typically go through 8 gallons of RO daily in my endeavor to maintain good growing conditions.
I monitor the humidity using several meters scattered over the growing area. The fogger is on a humidistat set at 60%.
Too low humidity for several species of orchids would not be appreciated and for most species, would invite increased pests (mites) and poorer performance.
