What do you use to fog up your greenhouse/grow rack? I have a ultrasonic fogger but it wont work in disstilled water only in tap water i think it might be the pressure and here is the link to what i have. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=200556788029&ssPageName=STRK:MEWNX:IT
In the first pic of this last update.. on the table, right side. Walgreen's special.. There's another on the floor under the table in the second pic. But that one is a cool mist so I don't use it much. I fill the white trays the plants are in with 2gal. of water once a week. Plants seem to love it, and it helps keep the humidity up around the plants.
I doubt the humidifier doesn't work with distilled water.. you should stop using that tap, it'll fry your fogger.
