The agricultural industry is constantly searching for solutions that allow for the maximization of food production in a sustainable, efficient, and profitable manner. One emerging trend is indoor vertical farming, an innovative method that presents significant differences compared to traditional agriculture and even greenhouses.
Indoor vertical hydroponics involves growing plants in a controlled environment under specific conditions, without the need for soil. In this method, plants are grwon in vertical towers that use automatic irrigation systems and nutrients dissolved in water. Unlike traditional agriculture, this system allows for year-round plant production, unaffected by external weather conditions.
One of the main benefits of vertical indoor hydroponics is its high resource efficiency. By not requiring soil, the amount of water used can be up to 95% less compared to traditional faming. Additionally, this method takes up less space and allows for higher crop density, thereby increasing productivity compared to conventional greenhouses. Another difference of indoor vertical hydroponics is it’s ability to minimize the use of chemicals, herbicides, and pesticides. By precisely controlling the growing environment, pest and disease problems are reduced, resulting in healthier and safer food for human consumption.
Vertical hydroponics is opening up new opportunities for producing fresh food in areas with complex logistics, adverse climates, and where there is limited land. However, like any system, indoor vertical farming also has its disadvantages. One of the main challenges is the need for significant initial investment in infrastructure and technology. Additionally, constant monitoring and maintenance of irrigation and nutrient systems can be complicated for some farmers.
On the other hand, traditional greenhouses also have their own advantages and disadvantages. Greenhouses are enclosed spaces that allow for some control over temperature and humidity, favoring plant growth. However, their dependence on sunlight and seasonal limitations can affect production. Additionally, depending on the irrigation system, greenhouses may require large amounts of water and may be more prone to pest and disease problems.
Operating in greenhouses can optimize the use of labor compared to field operations, but vertical agriculture further facilitates operations, reducing labor costs through space efficiency and variable control. Greenhouse production is a solution that requires large land areas, which is why vertical agriculture facilitates food production in urban areas. The lack of space in cities is a challenge for traditional and greenhouse agriculture, but vertical agriculture allows for the cultivation of food in buildings and vertical structures. This reduces the distance and costs of food transportation, as well as land and water usage, providing fresh, nutritious, and freshly harvested vegetables to restaurants, homes, and the end consumer.
Regarding traditional agriculture, its main strength lies in its accessibility and low initial cost. However, this cultivation method is subject to weather conditions, may require large land areas, and carries higher risks compared to greenhouse or vertical hydroponic production.
Growing in greenhouses or through indoor vertical farming makes food production more sustainable and efficient. However, it is important to know when it is more convenient to use a greenhouse or a vertical farm. Here, we summarize the points that can help you select the best option:
- Limited spaces: Vertical hydroponics is ideal for places with limited space, as systems can be vertically stacked, making the most of the available surface area. This is especially useful in densely populated urban areas where space is scarce and expensive. In 100m2, you can produce the equivalent of 15,000m2.
- Water efficiency: Vertical hydroponics uses much less water compared to conventional greenhouses, achieving zero waste. This is because water is recycled, and excess humidity is condensed and injected into the irrigation system. In water-scarce regions, such as arid or semi-arid areas, vertical hydroponics can be a more sustainable and cost-effective option.
- Higher yield and crop density: By growing vertically, it is possible to increase plant density per unit of surface area. This allows for a higher harvest yield compared to conventional greenhouses, where plants are grown in the soil or beds.
- Fewer pests and diseases: By growing in a vertical hydroponic system, the need for soil is eliminated, reducing the incidence of soil-borne pests and diseases. Additionally, these farms are installed in enclosed spaces, protecting plants from environmental contamination and producing completely safe crops.
- Greater environmental control: Unlike conventional greenhouses, vertical hydroponics allows for greater control over environmental conditions, such as light, temperature, and humidity. This can be beneficial for the cultivation of plants that require specific conditions and for optimizing plant growth and development, especially in areas where climates are not ideal for agricultural production.

In conclusion, indoor vertical farming presents itself as a promising and sustainable alternative in the agricultural sector. It’s differences from traditional agriculture and greenhouses result in greater efficiency, reduced resource consumption, healthier food, and the ability to produce in areas with complex logistics and unfavorable climates. However, it is important to carefully evaluate the needs and capabilities of each project before deciding which cultivation method is most suitable. Vertical indoor hydroponics can be an excellent option for those looking to maximize food production in limited spaces and throughout the year.
