The stratum of light dispersal make by diffuse app and glass is commonly known as Haze in the marketplace . However , the full term Hortiscatter provides more data about how the visible radiation is diffused .
The use of the term Haze in nursery culture spring up with the first trials with diffuse light . But this term was never actually intended for deoxyephedrine . It comes from the American ASTM-1003 trial method which was design for plastics and indicates the transparency of those charge card . For materials with a Haze greater than 30 % , however , this test method is no longer usable . In other Bible : it does not properly utter the abstemious dispersal . especially not for looking glass .
With no alternative available , the term Haze became commonplace in glasshouse cultivation . Haze indicates a percentage of lighter that is scattered more than 2.5 ° from the incoming angle . In showcase of 60 % Haze , 60 % of the incoming light is scatter more than 2.5 ° from the incoming slant of incidence . This percentage does not allow for enough information about the light diffusion , but because most provider practice the same measuring equipment , the Haze - gard , it was generally understood in the food market .
Over time , however , criticism start to be voiced by growers , specially with obedience to spread glass .
HortiscatterWhen the NEN2675 standard was update , Haze was supplant by Hortiscatter . Although the update standard has now been in use for nearly two years , the term Haze still die hard .
Like Haze , Hortiscatter is verbalize as a percentage between 0 and 100 % . exculpated meth has a Hortiscatter of 0 % , while a material that evenly scatters incoming light over all angles has a Hortiscatter of 100 % . Both diffuse coat and diffuse shabu can be characterize with the Hortiscatter .
Diffuse coatingsThe Hortiscatter of ReduFuse and ReduFuse IR depends on the thickness of the coating , which in turn calculate on the number of buckets apply per hectare . The floor of clean diffusion by both coatings and diffuse glass expressed in Hortiscatter is generally lower than the Haze time value . It is even possible for a Haze of 70 % to coexist with a Hortiscatter of 40 % , but commonly the value are closer together .
Whatever the pillow slip : the higher the Hortiscatter , the better the diffusion of the light in the crop . And that reduce focus , promote more even growth , better product and higher calibre .
