Aeroponic fogging / hydroponic foggers may be used for many horticultural applications including root fogging, foliar feeding, growroom & greenhouse humidity generation even ultra low volume / ULV pesticide application. These ultrasonic foggers are the ultimate aid to propagation and production as they can be used to create the perfect environment below and above "ground level" for plants to grow. The aeroponic fogger / hydroponic fogger operates by oscillating at a frequency of approximately 2 MHZ which is two millions vibrations per second. At this frequency, water is nebulized into a cold fog / dry fog which can support the needs of plants using an ultra low volume / ULV of water and nutrients. Another benefit of ouraeroponic fogger / hydroponic fogger is that it generates an extremely small droplet that averages only 2.5 microns which is small enough to be absorbed by roots and leaves on contact and how it can be effective using only an ultra low volume of liquid.

In the latest edition of How-To Hydroponics, we show you how to build the base fog generator and adapt it to a dutch pot garden system as a hands on excercise. While the practice of using nutrient fog to feed ones plants is still quite new, it nevertheless produces unquestionably vigorous roots below strong-stemmed plants with lush foliage and extensive lateral branching. These traits are due to the increase in fine root hairs caused by the abundant amounts of oxygen and fine particles (water or nutrient) apparent to fog. The high levels of oxygen and nutrient/water saturation in conjunction with proper lighting, allow the plant's metabolism to work at a dramatically increased pace.

Because the Dutch Bucket fogger is still in it's early stages, it's design will probably be subject to change in the future. To start with, we used a 14 gallon rubbermaid container as a base for the fogging unit. After installing the Fan, PVC, and the triple transducer module, we planted a mix of both sunflower and chili seeds in Perfect Starts, and inserted some into net cups and others directly into grow site plugs which rest in pre-drilled holes in the lid. To assure perfect symmetry in your grow sites, you may want to download the lid drilling templates found here. These are merely suggested layouts based on cup sizes, but do provide the exact mathematical measurements needed to cut the lid to the perfect size. From it's inception until right now, the roots and growth of each plant has been nothing short of incredible.

We do recommend having prior experience with hydroponics, as this project is still very much an experiment. Please feel free to use this information to build upon and construct your own fogging system! Here's the pieces we used:

• Triple transducer module w/ teflon coated discs
or try a Single Transducer Module
• 10' of ½" closed cell gasket tape for sealing lid
• 18CFM 12V DC Fan
• Polyester batting to snugly seal the fan into the PVC
