Polythene Cover
Lumisol Diffused 
Means the overall light reaching your crop is reduced by around 2%. This reduction in light creates a slightly cooler environment, up to 4°C lower at midday in mid-summer, which can be a considerable benefit to many crops especially in the sunnier parts of the UK. 

Lumisol Clear 
Is a UV ’open’ polythene film, allowing UV light to reach your plants. This can have many benefits for both edible and ornamental crops, such as enhancing the fragrance, taste, colour, earlier harvesting and longer post-harvest shelf life.

Anti Hot Spot Tape

It acts as insulation between the metal and the polythene to prevent the build up of heat in the steel frame being transferred to the polythene. Extends the life of a polythene sheet by at least one year.
