At PanAmerican Seed , one simple question comes first : which innovative products can we uprise to make your company more successful ? In social club to reply optimally to this , the company invested in modern raw nursery departments , and the PARperfect screen answer from Svensson was chosen .
PanAmerican Seed is an outside stock breeder and producer of seed - grown flowers and vegetables with thirty locations around the world . About thirty harvest are bred at the breed company in Venhuizen : annual and two-year perennials , veer flowers , and potted plants . With the novel building , the number of greenhouse departments has been expanded from ten to eighteen , and a new line of work space and office construction have been create . “ We want to be a mod company , not only for our client but also for our staff . This includes all facilities that make it potential to grow even more sustainably , expeditiously , and innovatively , ” says Tim Bouwman , Greenhouse Operations Manager at PanAmerican Seed .
The breeding society play with close mate for the new edifice . As far as the screens are relate , the choice was made to install Svensson ’s PARperfect screen result , according to Bouwman . “ We want to give the crop an optimal climate at the dispirited potential vim costs . In combining with the young climate computer , we attempt to optimise the climate : for the newly seed seminal fluid in the plug phase , the craw that grow and blooms in the cultivation phase , and the final craw during the finishing and harvest phase . That postulate all different light horizontal surface . ”
High - quality light distributionWith the PARperfect filmdom , an optimal light level can be accomplish all year round , explains Bart Bakker from Svensson . The Harmony 2047 FR and Harmony 7247 FR screen were choose for PanAmerican Seed . “ The unwashed feature of the Harmony screens is the high - tone light distribution so that sun penetrates deeply into the crop and is distributed more evenly . There is less prospect of harvest burning , more light , and a grim temperature , ” he says . “ upright dispersion of light over the intact plant results in gamy productivity and a stronger , healthier crop . You also have better quality of the harvested production due to a lower crop temperature . ”
With PARperfect , the CRT screen level in the nursery can be controlled ceaselessly , from 20 to 100 percent , just like a light dimmer , Bakker keep on . A combining of at least two concealment is assumed . The bottom cover is always a Harmony PARperfect climate concealment . “ The emplacement of the screens is ceaselessly adjusted based on the loudness of the sunshine ’s shaft of light . This keep the low-cal level at the crop level incessant , regardless of the time of year or prison term of solar day . Thanks to the very high diffusivity of the PARperfect mood screen , the light distribution at the crop tier is optimum . Every plant gets the same amount of light . ”
appraise box above screensSvensson recommends a measuring box above the screen , a must - have , say Bakker . Especially with the high energy damage , such a measuring box quick pays for itself , according to the consultant . “ of course , a fissure is often left in the screen when moisture rises in the refinement area . To check whether this is really necessary , it is better to also measure above the climate screen . The entwine screen cloths can easily transport moisture , supply the divergence above and below the screenland are gravid enough . With an absolute moisture deviation of 6.4 grams / m3 , the silver screen allow 47 Gram / m2 of moisture to pass through . Double - sided external respiration above the blind can increase this upshot . A spread of 2 or 3 pct easy means a 10 per centum red in vigour savings . That ’s a shame , especially if you could have drained wet through the screen . In addition , gaps often cause an uneven mood . ”
lead to a sustainable futurePanAmerican Seed does not yet have a measuring boxwood above the screen , but it does have outside moisture measurement , PAR sensors , a Pyrgeometer , and a Modern IIVO clime computer set up . The challenge now is to get start with the Modern dick as quickly as possible , says Bouwman . “ That is a collaborationism between us , the installer , and the provider . We hope to be able to use these tools in the long term to save on lighting , screens , heating system , and ventilation . Everything we get from exterior is gratuitous . ” Breeding is a metre - consume and labor - intensive appendage , and we also want and must contribute to sustainability , he continues . “ That is one of the goals within PanAmerican Seed . This winter , all existing lamps will also be replaced by LEDs , and we will search the path to a heat pump . This create us in full ready for the hereafter . ”A challenge projectThe new PanAmerican building was recently completed and the greenhouse have been in use since the summer . The screens were instal by Alsemgeest Screen Installations , a subsidiary of glasshouse builder Nobutec . The installation of the blind went well , say director Marco Geeratz . “ It was a challenging project . The dispersion society consists of several smaller departments with many corridors in between , they are not standard greenhouses . That made the induction of the screens a moment more complicated , but we are fully equipped for that . We set up the screens department by department , the greenhouses had to continue hermetically sealed . All in all , a courteous line . ”
prescribed first experiencesThe first experiences with the screens in the new department are convinced , says Bouwman , especially in the quid department . “ There , we experience a diffusor light that we can control continuously . We were able to grow a beautiful product there this summer . If you lead off with good untested plants , further polish becomes well-heeled . A problem for us is the high temperature in the summer . We are used to having Methedrine around Pentecost , but in nine out of ten cases , you will have bad weather the following week . And on non - gay days , the chalk stratum is a nuisance . With the new clime sieve , we can await longer before chalking and move out it sooner . ”
As mentioned , the two highly diffuse Harmony screens leave in a piano , balanced lightsome image , and all plants receive the same amount of light . That is also significant because we do a lot of tests in the nursery , Bouwman conclude . “ The breeders must be able to make critical selections . We do n’t require any gaps or shadow spots in the screen cloth . Because the more uniform the department , the more objective the breeders can work . ”
