Soilless cultivation is becoming one of the most discussed topics in the world of agritech and sustainable production. However, there are different approaches-hydroponics, aeroponics, aquaponics-that are often confused with each other or compared superficially. In this article we take a clear and technical look at the differences, advantages, limitations, and real-world applications of each system, including comparing them with traditional agriculture.

1. Conventional farming: the starting point

Conventional farming uses the soil as the central element.
It is a natural system but has variables that are difficult to control:

  • Dependence on seasons, climate and geography

  • Need for pesticides and treatments

  • High variability in yields

  • Waste in supply chain due to transportation and storage

  • Intensive water use (80% of the world's fresh water goes to agriculture)

Pros: accessible, cheap to start, known by all.
Cons: unstable, inefficient, unsustainable in the long run.

2. Hydroponics: growing without soil, with water and nutrients

Hydroponics replaces soil with a nutrient solution that contains all the macro- and micro-nutrients needed by the plant.

How it works

  • Roots grow in water or inert substrates.

  • Water is recirculated → consumption reduced by up to 90%.

  • Key parameters are EC, pH, dissolved O₂, water temperature, light.

Advantages

  • High control

  • Faster growth

  • No pesticides

  • Higher and consistent yields

  • Ability to grow indoors 365 days a year

Limits

  • Requires technical expertise

  • Sensitive to errors in nutrient solution management

Applications

  • Vertical farms, hi-tech greenhouses, advanced home systems (such as Tomato+ ones).

3. Aeroponics: suspended roots and nutrition by spraying

Aeroponics is an advanced variant of hydroponics in which roots are not submerged in water, but remain suspended in air and are sprayed by a highly oxygenated nutrient mist.

How it works

  • Cyclic nebulization of water + nutrients

  • Highly oxygenated roots

  • Need for closed and controlled environment

Advantages

  • Maximum oxygenation → very fast growth

  • Even lower water consumption than hydroponics

  • Excellent for microgreens and fast-growing plants

Limitations

  • Technique very sensitive to malfunctions

  • Requires reliable hardware (pumps, atomizers)

  • Risk of root stress in case of interruptions

Applications

  • Professional R&D systems

  • High-precision cultivation

4. Aquaponics: the integration of hydroponics and fish farming

Aquaponics combines hydroponics and aquaculture:
fish produce ammonia, which is transformed by bacteria into nitrates, which become fertilizer for plants.

How it works

  • Closed ecosystem: fish + bacteria + plants

  • No synthetic fertilizer

  • Nutrition dependent on biological balance

Advantages

  • Nearly self-sustaining system

  • Reduced environmental impact

  • High educational and experimental value

Limitations

  • Complexity in managing nitrogen cycles

  • Sensitive to temperature and fish diseases

  • Lower yields than hydroponics/aeroponics

Applications

  • Educational projects

  • Small domestic systems

  • Catering with farm-to-table concepts

5. Direct comparison: what is the best system?

System Speed of growth Control Complexity Water consumption Yields Notes
Traditional Variable Low Low High Variable Depends on climate and soil
Hydroponics High High Medium Very low High Indoor agrifood standards
Aeroponic Very high Very high High Very low Very High Ideal for R&D
Aquaponics Medium Low High Low Medium Natural, non-industrial ecosystem

Conclusion:
there is no absolute "best" system, but hydroponics (especially in controlled systems like Tomato+) is the best compromise today between:

  • productivity

  • stability

  • scalability

  • operational and energy sustainability

6. Which system is best suited for vertical farming?

Vertical farming requires:

  • total control of light, water, nutrients, microclimate

  • repeatability and scalability

  • advanced automation

  • software + AI integration

For this, hydroponics and aeroponics are the most widely used techniques.

Aquaponics is not suitable for professional vertical plants.
Traditional cultivation, of course, is not applicable indoor on levels.

7. Why Tomato+ uses an advanced hydroponic approach

Through our automated systems, remote control, and integration with AI and advanced sensors, Tomato+ optimizes the growth cycle:

  • automatic management of EC, pH, nutrients and water temperature

  • Variable spectrum LEDs with independent channel control

  • AI-generated dynamic growth plans

  • reduced waste and maximum yield even on compact plants

The goal is not just to grow, but to standardize, optimize, and scale up fresh vegetable production to cm0.

8. Conclusion

The differences between hydroponics, aeroponics, aquaponics and traditional cultivation are not just technical: they involve different levels of control, sustainability and scalability.

On the road to resilient, scalable and climate-independent food production, hydroponics represents the most robust technology today - and Tomato+ brings it directly into homes, professional kitchens and research labs.
