Application and use of Witvast
Application
Many crops are sensitive to excessively high temperatures or too much solar radiation. Witvast reflects sunlight, helping to improve the climate inside the greenhouse. Witvast contains calcium carbonate and other active ingredients that, among other things, ensure good adhesion to the greenhouse roof. It is easy to apply to glass, plastic film and polycarbonate sheets. The standard dosage is 25 kg of shading product mixed with 100 litres of water. This produces approximately 115 litres of solution, sufficient to treat 500 to 700 m² of greenhouse roof.
Shading and duration
Witvast provides a shading duration of at least two months. This makes Witvast an ideal product for a possible second application during the growing season. The actual duration and level of shading depend on the dilution ratio and weather conditions.
Product range
If necessary, La Blanche Cleaner can be used to remove the shading product or any remaining residue. Our product range also includes the shading products La Blanche en La Blanche Liquide. as well as glass cleaners, biostimulants and personal protective equipment.
