The West Country TV Cup was presented to Valcent managing director Chris Bradford at the official launch of the VertiCrop at Paignton Zoo.
The BBC's Countryfile presenter, John Craven, unveiled the innovative product at the ceremony.
South West in Bloom judge Jon Wheatley said: "We were extremely impressed with this project and its future potential."
The VertiCrop offers a high-density vertical growing system which Valcent claims can increase the production volume of field crops by up to 20 times, while using just 5% of the usual water requirement.
It uses trays on a looped dynamic conveyor belt with automatic feeding stations to grow plants more efficiently.
Bradford said: "We are justifiably proud of our revolutionary new food production system and delighted that it has been selected to receive such an honour."
