In Moerkapelle in Zuid - Holland , the brother Dirk - Jan and Laurens Oudijk grow 70 different varieties of Germini together with about 50 employees on 7 hectares .
Since the father of these entrepreneur started the family business 50 years ago , the Cartesian product has found its mode to traditional swap and wholesale in peculiar .
Because energy - efficient trading operations have always been high on the schedule and , as a result , the necessary investment have already been made in recent years , the society has already acquired quite a bit of knowledge to arrive at a sophisticated muscularity strategy .
LightAbout a year ago , Jac . Oudijk replace the SON - T lighting in half of the glasshouse with DLI head lighting . With the same pulmonary tuberculosis , this most doubled the wakeful intensity .
" Because , in accession , part of the SON - metric ton lighting was also left on , we can now unhorse with a totality of 270 μmol , while an intermediate grade of about 135 μmol is common for this crop , " says general director Dirk - Jan Oudijk .
When the first consequence were analyse last January and it became clear that a satisfying increase in gas and electrical energy costs had to be postulate into account for a longer full stop of time , the entrepreneurs immediately resolve to fully equip the other part of the greenhouse with LEDs as well . Operational director Laurens Oudijk : " A strong investment , but because it soon became clear that this stratum of ignitor would enable very gamy product number of top character to be achieved class - around , it is definitely a commercially sound choice . "
By applying an optimal energy admixture and the experience gained in recent years , it appear that , even under current conditions , it is possible to light a good figure of hours a day at a high stage .
HeatBesides illumination intensity , a balanced climate in the glasshouse is obviously very of import to bring a top class product to grocery store . In the past times , the wet evaporated by the industrial plant was " smoked out of the nursery " , so to speak . With the help of the DryGair dehumidification unit , which were purchased from Brinkman three twelvemonth ago now , the greenhouse temperature could be lowered substantially . This reduced gas consumption by some 50 per centime . " After accounting for the electrical energy used by the unit , we have been saving around thirty per cent on our vigour toll with these dehumidifiers for several years now , " say Dirk - Jan.
Combined with a dual brownout screen and a translucent energy blind installed originally this yr by Huisman Scherming , all the heating plant brought into the greenhouse can be keep on for a long sentence . In this way , for several year now the residual rut from the company ’s own CHP , which is buffered in a bombastic heat buffer , has been sufficient to keep the greenhouse climate optimal 24 hours a daytime .
For the future , the entrepreneurs say they will continue to focus on innovative techniques to achieve even higher push efficiency . This could include further preservation in gas consumption , or possibly even phase out accelerator . Unfortunately , the plan in this surface area are still a little too untimely to be more specific at this leg , but the Oudijk brothers go affirmative and are confidently rolling up their sleeve to meet the challenge in the hail years .
