Baltic Freya and many horticultural academics noted that hydroponics is a stepping-stone technology that shall soon give way to more advanced irrigation, more control enabling and higher yielding technologies like aeroponics and fogponics. Therefore, Baltic Freya has taken the concept of growing plants in aerosol and embarked on a journey to eliminate its flaws, to reinvent and improve it.

Advanced Irrigation

Fogponics & Aeroponics

Both aeroponics and fogponics are relatively new growing techniques in greenhouse farming, indoor farming, vertical farming, and urban farming worlds. Both can be defined as plant growing methods when the roots of plants are hanging in water and nutrient aerosol, mist, spray, fog. Nevertheless, no matter how you define or classify these systems, they have already proven their superiority to hydroponics and soil-based farming. You can read more about it in this general introduction.


Advantages of Aeroponics and Fogponics

No root disease

Root disease is a big problem for hydroponic farmers. If one plant in the production line gets it – every plant does. That’s not the case in aeroponic and fogponic technologies, because fog is an awful carrier of disease, quite often fog generators, high pressure or ultrasonic, rips apart any cellular organisms too.

More oxygen in the root zone

Aeroponics and fogponics are superior to hydroponics on this issue because oxygen solubility in water has a natural limit, when in aerosol environment there is more oxygen than needed by the plant.

Better nutrient uptake

Because of the increased aeration of the water nutrient solution there is more oxygen for the roots of the plant, therefore it enables faster and better nutrient uptake, metabolism, stimulating growth and preventing formation of pathogens.

Disadvantages of Aeroponics and Fogponics

Aeroponics disadvantages

The biggest issue of aeroponic systems is clogging. HPA (high-pressure aeroponics) uses high pressure nozzles that have extremely narrow and small spraying holes for water nutrient solution spraying. Naturally, that means – nozzles clog up easily. When they clog up, your crops do not receive water and nutrients that they need. Without moisture the roots will dry up rather quickly and the result shall be death of your plant.

Fogponics disadvantages

Fertilizer salt build up clogs ultrasonic misters that fogponics use. Yet again cleaning and maintenance becomes a serious issue. The most important part of the ultrasonic foggers is piezoceramic disk or membrane. These piezoceramics crack over time, then the equipment stops working, doesn’t generate fog and your crops die. Another technical flaw  is energy inefficiency – 90% of the electricity used is converted into heat. Moreover, the extremely small size of the water droplets results in high surface tension of the water droplet which makes it hard for the droplet to stick to the roots.

Baltic Freya Mission

As you can already understand, aeroponics and fogponics are superior to hydroponics and soil farming. Naturally the question arises – why aren’t these advanced irrigation technologies widely used? The answer is quite clear in our eyes – difficulty of operation, maintenance and technical flaws that cost too much. Having this in mind, we formed a very clear and strong goal. We need to eliminate all flaws of growing in aerosol and utilize its benefits. We need to create Fogponics 2.0.
