I was just wondering what everyone's opinion is on warm mist vs cool mist humidifiers in the grow room/tent? I currently use warm. My tap water is over 500 ppm most of the time. So if I use tap water, I have to clean the humidifier at least 1 or 2 times per month. So most of the time I use rain water but it's a hassle collecting and storing it. On the other hand if I used a cool mist would it put impurities in the air with the tap water so hard? And if you use the tap water in the humidifier it is also bad for your carbon filter. What's everyone's views on this?
