SOUTH AFRICA: “The Face of Future Farming” Aeroponic & NFT Systems

Impilo Ponics is a South African based enterprise and was formed 3 yrs ago with a mandate to design various vertical growing towers to meet the ever-increasing demand for sustainable fresh nutritional food security produce especially in rural poverty-stricken areas on the African continent, consequently, we identified that our designs are also in demand for Urban based populace by means of individual residential units that allow for space-restricted dwellings Ie residential apartments, townhouse dwellings, underutilized rooftop areas to name a few.

The tower systems are made up of modular panels made from recycled plastic with various additional additives for color and UV stabilization, the unique design of the panels have the advantage of “flat Packing” which allow for compact packaging reducing logistical transportation costs both locally and Internationally, the tower designs allow for a very simple DIY assembly in a very short period of time with minimal effort and no tools involved.

We have two discipline options in the way of Aeroponics ( high pressure misting irrigation 30 >>50 Micron mist) and NFT ( a low pressure spraying irrigation 200 > 250 Micron spray), the modular design allows for additional tower segments to be added as tower height extensions as and when the users want to increase growing capacity for higher yields of the cultivars planted in the towers, we promote “multi planting” in the growing pockets of the tower for example:- Chillis x 3 plants, Basil x 3 plants, Spinach x 3 plants, Peppers x 3 plants, etc, this means that in an 84 pocket tower, for instance, you can plant up to approx. 250 plants vertically in a 1.5m2 footprint area, the system is a soilless growing method that reduces the need for fertile soil as a growing medium and allows the flexibility of dead space utilization.

The Aeroponic system only requires a timer-based irrigation time cycle that drastically reduces both energy and water source consumption - the towers only consume on average 2 litres of nutrient water source per day and the pressure pump energy usage as little as 30 watts per day, this lends itself to utilizing a small affordable solar panel system to run the towers, rainwater collection can also be utilized to sustain the water source, the end result being that we have an “off the grid” solution especially for areas with limited resources.

The NFT solution uses more or less the same amount of both energy & water consumption and again can be utilized into an “off the grid” solution.

The main difference between the two systems is that the Aeroponics generates a highly oxygenated nutrient-based mist that adheres to the root zone and during the ‘rest period between cycles” allows up to 90% of absorption of the Nutrient based nutrient solution, this encourages a shorter maturity of both plant growth and yield. 

The NFT system has continual spray irrigation of root zone very much on the hydroponic principle but in a vertical environment instead of a horizontal environment, however, the irrigation cycle can be setup through a programmed timer at prescribed time periods before dehydration of the root zone takes place, all this depends on the cultivar for hydration requirements for example:- lettuce requires regular irrigation where chillis/peppers/tomatoes, etc require less

The tower designs also allow for a very simple conversion from NFT to Aeroponics at the discretion of the end-user.

The Impilo panel system also allows for a multitude of tower sizes and designs to client specifications for example:- we can create square towers, hexagonal towers, Cylindrical towers of any size and height.

Our latest designs are introducing Aeroponic Living walls,  horizontal “tuber” aeroponic growing chambers (baby potato yields of up to 20Kgs per m2 surface area on a conservative 100 day growing cycle -comfortably 3 growing cycles per annum).

We also design and manufacture modular greenhouses as a turnkey solution for Micro farming to commercial size operations, budget-related affordability for a new generation of smart farming entrepreneurs, and micro-farming opportunities.
