Fogponics, or fog and ponics (labor) can be defined as working fog. In its simplest meaning, in fogponic system, growers use the fog to grow plants.
The fogponics system uses electric foggers to pump and vibrate under pressure to transform nutrient and water mix into humidity, like the humid atmosphere found in the rainforest.
This creates a constant humid and nutrient-rich fog for plant roots
With fogponics, the root system can have full coverage as the tiny droplet size of the gravity-defying fog can travel and penetrate all space around it.
Fogponics uses a suspension of nutrient-enriched water to deliver nutrients and oxygen to plant roots.
This is in contrast to geoponics and organogenic which use soil and organic materials as the primary source of nutrients (as well as the growth medium).
Traditional hydroponics which uses a submersion of nutrient-enriched water as the primary nutrient source (using an inert, or no growth medium).
The difference between fogponics and other forms of aeroponics is that while aeroponics typically delivers nutrient rich water to the roots using a spray (relatively large particles in air),
Fogponics uses one of a number of mechanisms (for example ultrasonic, compressed air, or heating elements) to form a suspension of much smaller particles of water (5–30 μm), or even as a vapor.
What Are Fogponics Technique Benefits?
For optimal root growth in an aeroponic unit, the size of the average water droplet matters most:
If the average water droplet is too big, then not enough oxygen will be provided to plant roots.
If the average water droplet is too small, then plant roots will not receive the necessary nutrients to grow.
The sweet spot for water droplets dispensed from aeroponic misters or sprayers is between 30–100 microns.
Water droplets below 30 microns say 5–25 microns, need to be dispensed at an extremely high density.
So then, this is where a fogponic system can thrive: using a sprayer to consistently provide solution droplets that are between 5–25 microns is impractical, but an ultrasonic nebulizer (fogger) is perfect for the job.
Also, advocates for fogponics often point out that providing water and nutrients at the smaller particulate size results in faster absorption by plant roots and faster plant growth overall.
Fogponics can provide plant roots with a consistent nutrient/water mist that is between 5–25 microns per droplet in size.
This results in faster plant growth overall.
How Does Fogponics Technique Work?
Like any other active hydroponics system, plants are given with what they need, moisture, nutrients, oxygen.
They do not have to actively seek for these like in the soil counterparts.
All of their efforts are spent on growing, flowering, or sprouting (for seedlings), and root development (for cloning).
But unlike traditional Hydroponics, where plants get the oxygen from the water oxygenated by an air pump, Fogponics/Aeroponics works by hanging the plants in the air.
It is held by a tray/foam. The plant roots are suspended, so they have plenty of oxygen access.
Water is provided by plants via the foggers. The action is usually automated by a timer.
Fogponics operates just like aeroponics. But instead of using the water misting, the foggers are used.
They produce and atomize much smaller droplets than in aeroponics, usually less than 10 microns in size.
What Are Best Plants For Fogponics Technique?
Seedling, clonings: There is an excellent reason why fogponics works absolutely well with seedlings and clonings.
Green vegs: The fogponics also works best with green vegs, including lettuces, spinaches, kales, cucumbers, beans and so on.
Herbs: Most herbs like basil, mint, chives, etc thrive in the fogponic system as it is lightweight, and have a short growing life span.
