Deep Water Culture Our System and Innovative Approach

Phytoponics has taken an ancient hydroponic method and we have adapted and evolved it for use at scale by designing a range of Deep Water Culture (DWC) growing modules containing nutrient solutions which are kept oxygenated by built in aerators.
Plants are located in the growing module and the roots of the plant are suspended in the water which has the crop specific nutrient recipe and the correct amount of dissolved oxygen.
The growing modules are serviced by a computerised nutrient control system that maintains the nutrient and pH at optimum levels whilst also irrigating the rootzone of the plants according to a carefully designed inlet and drain duty cycles.

Phytoponics DWC Systems are specifically designed for soilless, substrate-less growing of nutrient intensive vine crops, soft / exotic fruits and high value crops such as medical grade cannabis.

The Key Benefits of our DWC Systems

Root Zone Control

The roots grow in a large volume of homogenous nutrient solution that enables consistency in rootzone conditions that can be controlled e.g. nutrient levels, pH, oxygen aeration and temperature.
A wide range of stresses can be induced in the rootzone to influence and produce desired crop physiological traits.

Our ability to control or influence nutrient and energy distribution throughout a plant enhances the yield and quality of the produce grown in our systems.
Rootzone management is at the heart of every Phytoponics system and it’s where our core R&D activities have been focused.

Yield Enhancement

Less energy is expended by a plant’s roots in adapting to the fluctuating rootzone environments seen in other less controllable hydroponic growing methods and this results in yield enhancement.

No Need for Substrates

Other common hydroponic approaches e.g. rockwool and coconut coir fed by drip irrigation have sustainability issues largely derived from the sourcing and disposal of non-recyclable substrates and high water consumption during processing and manufacture. Our DWC approach does not, as it uses the aerated nutrient solution as a substrate alternative.

Environmentally Sustainable

Phytoponics’ DWC approach produces less waste than other methods of hydroponics e.g. rockwool substrate and therefore we believe we offer a far more sustainable means of growing produce for the future benefit of the planet and its inhabitants. Furthermore, all the materials we use are multi-use and fully recyclable.
