Dry Hydroponics

Dry Hydroponics was designed to grow all possible varieties of lettuce. Not only the traditional varieties such as Butterhead and Romaine lettuce, the modern varieties also benefit from using the Dry Hydroponics approach to growing.

Growing crops with Dry Hydroponics provides a tremendous gain in production volume as well as production cost reductions. This is due to the efficient use of production space and the mechanisation and simplification of labour. Growing with Dry Hydroponics is easy and reliable. The return on investment in the Dry Hydroponics system is estimated at two to five years.

Increased production volume

Unique to the Dry Hydroponics system is the ability to adjust the crop spacing multiple times during the cultivation without disrupting the growth. This increases the production volume without necessitating an increase in production space.

But the increase in production volume does not stop there. Compared to standard approaches, crops also grow faster with Dry Hydroponics. Three factors stand at the base of this rapid growth. One is the light reflectivity of the system. Another is the microclimate around the leaves, which ensures an uninterrupted growth. The final factor is the sturdy root structure, which is the result of the constant availability of water, oxygen, and fertiliser in an unfluctuating environment.

The production volume is further enhanced by the seamless transition of successive growth cycles. All these factors result in an increased production volume of 100% up to 500%, without an increase in production area.

Increased productivity

Because all activities are focused around a central location in the company, Dry Hydroponics increases productivity. This location can be arranged both ergonomically and efficiently, guaranteeing good working conditions and improved logistics. This ensures high productivity without adversely affecting working conditions.

It is in the interest of large companies to implement far-reaching automatisation. The processing of 750.000 products per man-year (1750 hours) is feasible as a realistic estimation.

Customer is King

Dry Hydroponics is suitable to all varieties of lettuce. Romaine for instance, often difficult to get right, is now easily grown. The same applies to newer varieties of lettuce, such as Multicolors (different kinds of lettuce in one pot), Salanova, Multileaves, and Easyleaves. Need to grow different products at the same time? With Dry Hydroponics this poses no problem. Different crops can be grown in succession as well as at the same time.

Flowpacking? Mixing different varieties in one package? Harvest with roots for “living lettuce”? Cooling for the harvest? All of this, and more belong to the possibilities of the flexible Dry Hydroponics system. Due to the central nature of all activities, it is easy to tailor to specific customer needs. Dry Hydroponics has not only considered costs, but also the possibilities to add value to deserving, sustainable products.

The simplicity of Dry Hydroponics causes little necessary intervention. This not only cuts costs, it is also a leap forward in food safety and it makes growing crops with Dry Hydroponics sustainable and guarantees reliable supply to your customers.


Tasty and healthy crops

To ensure a healthy growth, crops need to be grown under the right circumstances. Through its innovative design, Dry Hydroponics provides sufficient fertilizer and oxygenated water 24/7. These constant circumstances improve both the taste and the crops‘ health. The design surrounds the leaves with a microclimate favorable to growth. In short, during cultivation the crops are maintained in stable and beneficial circumstances.

Beautiful crops

Growing with Dry Hydroponics guarantees beautiful crops, which develop in a natural way. The uninterrupted and balanced development of the roots, allow the plant to build strong leaves, so that the crop is healthy and durable. This ensures that symptoms such as tip burn and glassiness are no longer a threat.

In designing Dry Hydroponics special attention was paid to the microclimate around the leaves. Its airy design keeps the leaves dry. Because the system is clean and reflects light, the bottom leaves of the crop are also fresh and green.

Shelf life

A healthy and fair crop with strong leaves has a long shelf life. The solid foundation that Dry Hydroponics provides, guarantees sturdy plants with a long shelf life.


Dry Hydroponics’ new approach to crop protection is based on the prevention of situations that ordinarily harm crops. This is achieved in such a degree that intervention is hardly necessary.

The plants are also free from sand, soil, and weeds. Dry Hydroponics is such a clean approach to growing crops that they can be sealed immediately and are ready-to-eat.


The extraordinary performance of Dry Hydroponics helps to maximise the production volume per production area. Dry Hydroponics is not only sustainable in its use of space, it is also efficient in its consumption of water, fertiliser, and energy. By maximizing production volume while minimizing consumption of space, water, fertiliser, and energy ensures that both the physical and ecological footprint per crop are significantly reduced.


Dry Hydroponics is a closed cultivation system. What this means is that water that is added to the system is used only by the crops: the highest efficiency attainable!


The same applies to fertiliser. As no fertiliser seeps into the soil, nothing is wasted. This serves as both a cost reduction and a benefit to the environment. With other cultivation practices “redundant” fertiliser seeps into the soil, comes into contact with the groundwater, and adversely affects the ecosystem. Thanks to the closed Dry Hydroponics system this is a thing of the past.


The intensive production assures that all available space is used as efficiently as possible. Furthermore, fertile soil is no longer a requirement, as the Dry Hydroponics system can be applied anywhere.

New approach to crop protection

A healthy crop is robust and requires minimal protection. A sturdy root structure and sufficient light are the foundation for a robust crop; Dry Hydroponics provides that foundation.

Dry Hydroponics was designed with a natural barrier between the soil and the crops’ leaves. This approach helps to prevent prolonged periods of damp leaves, eliminating the possibility for fungi’s to develop.


Dry Hydroponics is highly energy efficient due to the major production increase without requiring additional energy. This drastically reduces the required energy per harvested crop. The water used by the system can further be heated or cooled using low quality energy. Producing lettuce without the use of fossil fuels is no longer a utopia, but a choice!
