Fogponics uses ultrasonic transducers (foggers) to turn nutrient solution into a cold fog of very fine droplets, typically under about 10 µm, which fills a closed root chamber. In theory, tiny droplets give roots both oxygen and nutrients with almost no water barrier.
In practice
In practice, fogponics is mostly used for cloning and small experimental systems. Common problems: transducers heat the solution, salts build up and crust on the discs, units wear out and need regular replacement, and fog alone may deliver too little water and nutrients to large flowering plants. Many builds combine fog with a spray or a shallow pool.
Evidence for full-cycle cannabis production in fogponics is limited to grower reports; treat it as experimental.
Don't confuse with
- HPA: pressure-driven mist with larger droplets.
- Humidifier fog: the same hardware, used for air humidity, not root feeding.
A humidifier adds water vapour to the air to raise relative humidity, used mostly for clones, seedlings and veg, or dry climates.Cloning is propagating a plant by rooting cuttings from it, producing new plants that are genetically identical to the donor.Underwatering is letting the medium dry too far between waterings, so the plant loses turgor and wilts, with limp, papery leaves and crisping edges if repeated.HPA (high-pressure aeroponics) mists roots with very fine droplets from a high-pressure pump and accumulator, giving maximum aeration but little margin for failure.Aeroponics grows plants with roots hanging in air inside a dark chamber, wetted by sprayed nutrient solution; low-pressure (LPA) systems use ordinary pumps and spray heads.A reservoir is the tank that holds a system's water or nutrient solution, the place where pH, EC, temperature and oxygen are measured and adjusted.The root zone is the volume of medium or solution where a plant's roots live, including its water, air, temperature, pH, EC and microbes.
