PRISMA®: diffused light and temperature reduction

“Baby leaf” salads and other greenhouse vegetables have an additional ally to grow and develop at their best throughout their life cycle.


Arrigoni presented new evidence on the effectiveness of PRISMA® thermo-reflective screens for this type of crop.

As proof, Dr. Antonietta Boffa, technical manager of production of Vitrosele srl and directly involved in the propagation and growth phases of the micro-propagated seedlings.

“Light is a very important component in our business – he explains – but it must be homogeneous in all periods of the year and, in the warmer months, we must be able to control the excessive heat that is formed in greenhouses. Since we adopted Arrigoni’s PRISMA® thermo-reflective screens, we have noticed not only a drop in temperatures compared to the previously installed solutions, but also a significant vegetative improvement of the plant, thanks precisely to the more balanced lighting given by these particular screens. Following this positive experience, we decided to adopt this solution also on three new hectares of nursery.

In the video, Dr. Antonietta Boffa – technical manager of the company Vitrosele Srl – explains how was the test.

The Vitrosele srl farm is located in the province of Salerno in the heart of the Piana del Sele. Specialized in the development of horticultural productions, in particular of the artichoke, the company represents an excellence of a district with a high rate of innovation in the horticultural sector.

The desire for innovation of this company has promoted the development, inside, of a research laboratory for genetic improvement and micro-propagation, of a nursery for the setting and development of seedlings, as well as of various test fields and greenhouses equipped. The ideal context, therefore, to test Arrigoni protection systems.

This explains the mechanism of action of PRISMA® heat-reflecting screens: thanks to the special LD-Light Diffusion additives formulated by the Arrigoni laboratory and added to the yarn in the production phase, the light spreads more evenly around the plant, even in the lower parts .

The PRISMA® white tape also ensures lowering of the temperature without reducing the passage of light in the PAR spectrum (Photosynthetically Active Radiation). These combined effects greatly reduce sunburn damage and improve the quality and quantity of production. The lower temperature also facilitates the work of the operators.
