For crops that are switched in the summer , this is the ideal time to apply AntiCondens to the interior of the greenhouse cover . It is a well preparation for the coming humid season , when condensation droplets deflect valuable sparkle . Tomato agriculturist Paul van Paassen has been using AntiCondens for three year , realise a light gain of 7 to 9 per centum .
The inside of a greenhouse back is cover with condensation for a orotund part of the year . This block a great spate of light , just during a time when every sun shaft is needed by the craw . When water vapour condenses in the manikin of big droplets , light transmitting drop by 9 % according to the calculations perform by Wageningen University & Research . Practice shows that few cultivator are aware of how much light departure this problem causes .
The optimally weak penetrable piddle film on the inside of the greenhouse cover is simple-minded to accomplish : by apply AntiCondens .
Left : without AntiCondens ; right wing : with AntiCondens
extra brightness gainAntiCondens administer pee vapour in a okay film across the glass . This easy improves light infection by 5 % . This also fix the problem of falling droplet in the greenhouse . When these droplets country on the crop , they alleviate the germination of moulds such as mildew or botrytis . As a result , the diligence of AntiCondens also has a harvest protection effect : the crop understandably becomes less sloshed . The piss runs to the condensation gutter .
The product must be applied to dry glass . For crops that are switch during the summertime period – such as cucumbers , gerberas , chrysanthemums and strawberries – this is the ideal time . This is because make in an empty greenhouse or nursery compartment is far more practical . moreover , it is also possible to apply AntiCondens in a greenhouse with a harvest in it , but then it is advocate that you try out if the craw is sensible to this treatment . Our own tests show that there is no problem with tomato , cucumbers and gerberas , but that it can get some impairment to roses .
There are different method acting for applying AntiCondens : specialised equipment is used that hinge on on the lowly heating pipe rail system ( coarse in vegetable crops ) while equally give Anticondens or a manual program with a sprayer lance . After covering , the intersection needs to dry out completely . It will then be in force for at least a year , however , if the greenhouse is cleaned using a cleaning agent , it will be washed off .
Van Paassen : 7 to 9 % light gain due to AntiCondensTomato grower Paul van Paassen in Bleiswijk in the Netherlands now has three years of experience with AntiCondens on glass ; more than anyone else ( AntiCondens on plastic has been around much longer ) . " We charter a sprayer pushcart from an agricultural leasing company so we can utilize AntiCondens ourselves . This cart moves at forty beat per moment along the pathways and sprayer AntiCondens against the glass . This way the merchandise is perfectly utilise to the glass , " he says .
In the past he cultivated the racy truss tomato variety Merlice . Today he develop the specialty tomato Strabena , a tasty small variety that because of its unequalled material body is live as the ' strawberry tomato ' and is sold under the brand name Rimini .
The crop rotation engage place in November , a period during which the greenhouse cover song is almost continuously dampish .
" It is important to go for the production on a teetotal daylight . what is more , it is ideal if the greenhouse is empty . The ware , renting the equipment and labour implicate surplus cost , but all in all the result are positivist : output is well mellow , " he says .
He has been overconfident about the upshot for three years . " The glass is far less wet ; you may well see this . And that lead in a tripping addition . Mardenkro took measurements here in the spring and in comparison to an untreated surgical incision , the lite gain was 7 to 9 % . This is a considerable amount and translates into high yield . "
