New greenhouses are construct for the first crop that will be grown in them . Most nursery are designed for heated cultivation and prepare for modified snow load . In a glasshouse for warm crop , the gutters and cover rods are lighter , and that does not suffice with a lumbering coke loading .
Technical specialist Theo Herngreen sees that entrepreneurs are presently switching more often from ardent to cold cultivation . The high price of gas is one of the causes of this craw switch . " The entrepreneur making the shift are not always aware of the import for their greenhouse . If snow devolve on a nursery in which no heating is used , that greenhouse has to be made secure . I advise entrepreneur to keep themselves well informed and ask their glasshouse builder , installer , or technical specializer from Interpolis . It is a necessary investment to maintain your business . "
From peppers to strawberry mark or from roses to hydrangeasWhen a crop shift is going to happen , entrepreneur energetically set about preparing their greenhouse for the fresh product , but that is not enough . Theo tells of his experience with entrepreneurs who switched from roses or peppers to hydrangeas or strawberry mark .
" For the new crop , much less heating is needed . One enterpriser had his natural gas connection cut back . Another one had it cut off . The enterpriser were not aware that they ’d have a problem in the wintertime . The glasshouse is not strong enough to nurse snow . That Baron Snow of Leicester can not be shed and there is a chance that the greenhouse could break down due to the free weight . Also , the greenhouses were not resistive to frost . Even at 4 degrees , the vents can freeze solid and spyglass can break due to meltwater result behind . "
Snow loadTheo says also that " a glasshouse in the beginning built for warm refinement is prepared for a snow load of 25 kg per m2 . We take into account that the temperature just below the greenhouse roof always stays above 12 degrees . The design takes into account that the greenhouse is heated in the winter . This decide the bearing capacitance . A greenhouse built for frigid cultivation is fix for 42.3 kilo per m2 . These nursery are built strong . call for your greenhouse constructor for an estimation of the posture capacity of cover and glass . That way you will know how much snow your greenhouse cap can take . "
From warm to cold cultivation?When switching from strong to insensate cultivation , almost no unheated nursery can hold up snow force per unit area . Theo gives the follow lead on behalf of Interpolis :
Not necessarily much more expensiveEntrepreneurs change over craw more often during the lifetime of their greenhouse , or they are using their nursery for longsighted than it was designed for . Theo , therefore , advises invest in the hereafter - proofing of a greenhouse by giving it a heavier physique . A greenhouse that is worthy for both cold and warm crops is the best solvent . The difference of opinion in investment is only 1 to 2 % of the leverage price . " By fall in a nursery a heavier build , it becomes strong and you may prevent many problem . The investing is also easy returned because there is no pauperism to hot up the nursery when it hoodwink . "
