UV Absorption - This new generation film combines all the benefits of “Luminance” (great thermic & light transmission properties). Unlike normal greenhouse films that prevent short wavelength UV light (UVB) from reaching plants, this UV transparent film allows UVB to enter the greenhouse thus enhancing the fragrance, taste & colour of the crops. In addition, UV transparent films promote plant anti-oxidants which are good for health & encourage stronger plants. This greatly benefits plant raisers & young growers as stronger plants can be easier to plant out thus saving time & raising productivity.
Anti-Fog (Condensation Reduction) - Thanks to its unique additive, ‘Lumisol’ is able to control the condensation of water on the film. Providing the film is properly installed, water will condense uniformly on the plastic sheet rather than form as droplets. This reduces the risk of water dripping on to the plants below and prevents the loss of light caused by these droplets, which can account for as much a as 25% light reduction.
Quality - Plant scientists from the University of Reading have shown that growing soft fruit crops under Lumisol can lead to early picking & improve a wide range of fruit quality parameters including the production of secondary compounds linked to human health, taste, fruit firmness & shelf-life.
Diffusion- Light diffusing polythene films scatter the light as it passes through. This enables the light to penetrate deep in to the plant canopy, as it hits the plant from all angles, not just directly from above. This ‘diffused’ light prevents the higher foliage from shading the lower parts of the plant.
Diffusion films allow more of the available light in to a polytunnel when the sun is low in the sky (which can be early or late in the day, and also during the short days of winter). This is because the ‘scattered’ light is deflected downwards in to the crop, rather than reflected as happens with glass and clear polythene.
‘Lumisol Diffused’ can reduce midday summertime temperatures by 2-4°C, although approx 2% of light transmission will be lost.
