Welcome to my DIY ultrasonic fogger thread. first i'm showing you just a cheap illustration of the fogger unit I will be building. Easily transports from room to room, can be used as a foliar feed system or can easily adapt to hydroponic systems. A picture is worth a thousand words. so take a look before i explain how it works.no humidifier required, runs on very little power and costs about $50-80 to make depending on how resourceful you are. compared to $350 and up in stores. If this exact fogger has been done before somebody please stop me.
