Working in a fairly hot low humidity environment. This bad boy blows out a nice cool stream of vapor. This completely straightened out my low humidity problem. I can change the amount in my 3x3 tent at will. Also has lowered the temperature by several degrees. On a different note my grandson got a respiratory illness just days after receiving this product. We have been running it wide open for the last 2 days and it is amazing. The “mater plants” will just have to wait a few more days. 5 stars!
