roho Vertical Aeroponic Farm

A new type of high-tech fabric, which from the outside looks almost like a completely normal plastered facade, but behind it there is a state-of-the-art vertical aeroponic farm. The trick is that the facade produces nitrate ions in a photocatalytic process from the nitrogen oxides in the air. The air masses are freed from CO₂. With this new principle of vegetable production, the rainwater that rains down over the textile facade is collected and used as fertilizer for production. The nutrients are fed to the roots in the form of a mist-oxygen mixture. This accelerates plant growth by 20% -30% as the nutrients are better absorbed. The textile facade meets several requirements. It ensures perfect light, wind and climate conditions for the plants and has a positive effect on the building's carbon footprint. R.A.S. (Roho Aeroponic System) enables computer-aided and extensive automation of the farm.


1. rohotex plus Fabric


The high-quality and durable special fabric for walls and roofs neutralizes nitrogen oxides in the ambient air. The rohoflex tensioning system, which has been evaluated and patented for many years, is used to fasten the fabric.

2. Aeroponic Tower


Inside, the tower ensures that the nitrate-enriched rainwater optimally supplies the plant roots. A large number of different types of vegetables can be grown in these towers.

3. Controller


The control technology developed by roho allows flexible and automated control of the processes. The modern user interface allows intuitive use via the Internet.



  • Consumer-oriented vegetable production of various types of vegetables.

  • No loss of nutrients due to the usual long transport routes.

  • No use of pesticides.

  • Reduces land consumption (100-200 heads of lettuce only need about 3/4 square meters).

  • Comes with only approx. 5% water compared to field cultivation.

  • Works in all regions of the world.

  • No negative impact on the environment. E.g. Groundwater level, no nitrate pollution in the groundwater.

  • Considerably less effort, as there are no more fields to plow and fertilize.

  • The laborious harvest with flocks of harvest workers is a thing of the past.

  • Demand-oriented production with little to no waste.

  • Lower investments - no tractors, no plowing the fields, regardless of the weather, simplified harvest.

  • and much more

Areas of application:

Shopping centers, restaurants and hotels, company canteens, use of orphaned exhibition halls or industrial buildings, occupational therapy and nutritional improvement in old people's and nursing homes, hospitals, market halls, roof terraces, etc.


For private users, the same procedure is available on a reduced scale. You can find out more about this on the website
