Making a Vertical Fogponics Tower is an easy way to start growing with Fogponics. Although, the easiest way to start growing with Fogponics is the 5 Gallon Bucket Hybrid Kratky Method. The one thing to remember with vertical hydroponic towers is that fog is heavier than air and tends to settle at the bottom. Therefore, we need to introduce the fog at the top of the tower and not the bottom.
One of the best ways to do this, and also use a smaller mist maker is to create a hybrid drip/fog system. To do this, you will have your Ultrasonic Mist Maker mounted at the top of the Fogponic tower (without the black float) inside an overflowing container that is fed nutrient water via a pump located at the bottom of the tower.
Depending on the size of your Vertical Grow Tower, you could use anywhere from a Single Disc Mist Maker up to a 12 Disc Mist Maker. The customer in this video uses a Single Disc Fogger mounted at the top of the tower. They pump nutrients to the top of the tower which feed the fogger and then overflows back down over the roots on its way back to the nutrient reservoir in the base of the tower. The fog that was generated during the cycle is then left behind for several minutes until the pump's next cycle commences.
100% Fogponic grows can also be achieved in a vertical tower as well. To do this, you would have an external fog generator that supplied fog directly to the top of the tower, and the condensated waste would be collected at the bottom of the tower. A 100% Fogponic grow requires a larger fogger to supply very thick fog, allowing the plants to receive enough nutrients. A 5-disc unit (minimum) should be used in a similarly sized fog tower if growing with 100% fog.
How a Vertical Fogponics Tower Works
A single tower runs as a hybrid. A repeat-cycle timer runs the pump, which fills a small cup at the top of the tube until it overflows the top. The water trips the mist maker's sensor and it fills the whole tube with fog; once it fogs out all the water, it shuts off until the next pump cycle. The overflow drips down over the roots and drains back to the reservoir - so roots get both fog and feed, and you don't need a big unit.

The cup is a separate piece mounted in the top of the tube. When the timer kicks the pump on, it fills the cup until it overflows the top - the water trips the fogger's sensor and it runs. Once it fogs out all the water, the fogger shuts off until the next pump cycle.
