Which combination of two crops in a greenhouse can be grown fossil - free and with less than 100 kWh / m2 of energy per class ? The Kas als Energiebron innovation programme posed this doubt to the Greenhouse Horticulture and Flower Bulbs Business Unit of Wageningen University & Research . That level best is likely manageable with a combination of seven months of honeyed pepper and 4,5 month of green potted plant . Researcher Arca Kromwijk ( WUR ): " It is very interesting to start with Department of Energy availability and front at desirable combinations of unlike crops from there . "
An Department of Energy consumption of 100 kWh / m2 ( electrical energy ) per year for two crop is low . The lookup started with peppers . By growing that craw from mid - March to the end of October , slight energy is ask in the summer ; in the wintertime months there is still energy ' left ' for another crop with a high value than pepper ( which has a very dull increase and production ) . Since there is less sunlight during that period , unripened pot plant are ideal : as they are used to a shaded environment they can spring up under low-toned promiscuous conditions .
This combining was enquire in WUR ’s Greenhouse2030 . The heading of this project is a dodo - free and emission - free culture with sustainable crop protection . No fossil fuel are used in Greenhouse2030 : the nursery is heated by heat from the light-emitting diode firing in the winter , latent heat ( from dehumidification ) , by sunlight and possibly heat extraction in the summer to forbid an imbalance in cold demand and cold yield of the heat energy pump . If all the electricity used is purchased green , the cultivation is gratuitous of fossil fuel .

combining of capsicum pepper plant and dark-green pot plantsThe inquiry in the Greenhouse2030 shows that the combining of common pepper and green potted industrial plant work well and remains within the maximum vim requirement . Both crops have a good product . Moreover , the glasshouse is designed in such a way that it can easily be rearranged for another craw . For example , the greenhouse has a lava floor on which either the flock or the white pepper substratum is placed : drainage piss can be drain via the floor , disinfected and reused . The pipe rail system is used in white pepper cultivation for internal transportation ; With the green pot plants , the tubes are lift to make an empty base quad for the Ø 21 atomic number 96 dope to be placed side by side . The tubes are still used for heat .
Pepper growers and mint plant growers from the research ’s supervisory citizens committee responded sky-high : aggregate two crops appears to have many advantage , while the conversion is relatively easy . Kromwijk ( WUR ): " This research bear witness that you’re able to look at get-up-and-go in a different path . That other view is on the nose what we take in the future . Next yr we will investigate a different combination of craw : melon in the summer with another completing harvest in the winter . "
