I live in North Carolina . Humidity is bi polar. in my house during the winter fluxes between 30 to 40%. Summer 50% inside. 

I preordered this one @ the end of last year and said it would ship out feb. 28th.. got it on the 27th. I think I paid 50 for it. It hooks up to my cloud controller. It came with a long collapsible tube so you can run it from the outside of the tent. Condensation inside the tube is my present problem wanting to drip inside the tent. So this case has given me a reengineering redneck project to do. lol

I set it inside for now. i know with the 6" exhaust fan on 10 the humidity only drops 2% so far , This thing keeps the air saturated in a 4x4
