UV open versus UV Blocking Films
SunSmart Green and Blue
In the top graph there are 2 lines - the red line is our UV open
SunMaster Diffused and Clear and the Blue line is our SteriLite.
The UV open films give your plants the same spectrum of UV that
your plants would have if growing outside. It makes cell walls thicker,
plants more compact and improves the colour of flowers fruit or
vegetables which have red or blue in their makeup. Research has
shown that Strawberries for instance will be ready for harvest about 1
week earlier than a normal film which normally blocks out the UV
below 350 Nms.
UV blocking films have the ability to reduce both fungal diseases
which need UV to be able to reproduce and spread, and aphids who
see in UV so if you take it away they can’t fly anymore. Research has
also shown that plants will have more foliage under UV blocking
SteriLite and it is especially good for salad crops.
In the bottom graph there are 3 lines. The dark blue jagged line is
the actual light spectrum recorded under a forest canopy on a
cloudy day. The Green Line shows the spectral transmission of
SunMaster SmartGreen and the blue line the spectral transmission
You can see that both of them have a curve which more closely
matches the curve of a forest canopy than the curve of the full
spectrum films which match the spectrum of a full sun savannah or
And all plants grow better in the correct spectrum of light.
...Poly tunnel covers are no longer just something to keep the rain out and keep it a bit warmer in winter. They should really be called spectrum filters which help you grow much better plants... Les Lane, Managing Director
