Protect your crops from excessive light with Q3 White
Q3 White is a medium-durability, adjustable, and environmentally friendly shading agent. It provides optimal protection against light with the flexibility to adjust coverage according to your needs.
Benefits of Q3 White:
- Adjustable Shading Percentage: Easily modify the protection level by adjusting the dilution.
- Medium Durability: Offers a balanced mix of durability and flexibility, making it suitable for various shading needs.
- Easy to Remove: Can be effortlessly removed with Removit after application or rinsing.
- Environmentally Friendly: Contains no harmful substances and complies with Dutch discharge regulations.
- Suitable for Various Applications: Ideal for short-term, intense, and periodic shading needs.
Adjustable and Cost-Effective Shading Agent
Not all crops require prolonged or mild protection. Q3 White is designed for these crops, offering medium durability and adjustable properties. It provides the same ease of use, application, and removal as Q4 White. This versatile shading agent is suitable for all types of greenhouses, whether they are made of glass, polycarbonate, film, or acrylic. Q3 White can be applied either mechanically or manually.
Environmental impact and storage
Q3 White contains no environmentally harmful components and meets Dutch discharge regulations. It is important to store Q3 White in a frost-free environment.
Easy removal
Q3 White can be easily removed from the greenhouse roof with Removit. After applying the appropriate dosage of Removit, the greenhouse roof will be clean after a few rain showers. If there is no rain for an extended period, a repeat treatment may be necessary. You can also choose to rinse Q3 White off with water immediately after applying Removit.
Difference between Q3 White and Q4 White
The difference in durability between Q3 White and Q4 White offers unmatched flexibility and various shading strategies. For maximum durability at lower dosages (less than 65% shading), Q4 White is recommended. For short-term or intense shading (more than 65%), Q3 White is the ideal choice. Additionally, Q3 White is perfect if you apply a shading agent multiple times a year, providing economic benefits. Q3 White is also excellent for greenhouse walls, which are less exposed to the elements than roofs.
Shading percentage
Q3 White makes it easy to choose the optimal shading percentage for your crop. By diluting the agent, you can precisely achieve the desired shading level. Refer to the table for the shading percentage relative to the number of buckets of Q3 White per hectare.
Application instructions for Q3 White
Calculate the required amount of shading agent by referring to the table for the desired shading percentage. Stir the contents of the bucket into clean water. Use enough spray liquid to evenly distribute Q3 White. The amount of spray liquid required depends on the application method. The recommended amount of spray liquid is 1,200 to 1,400 liters per hectare for mechanical application and 1,500 to 1,700 liters per hectare for manual application. It is recommended to stir the solution continuously or regularly during application. Apply Q3 White in drying weather on a dry and clean surface.

Q3 White and Q4 White is greenhouse shading paint based on calcium carbonate. Actually, only one difference between the two shading agents can be named, which is the extent to which it is weatherproof and thus its lifespan. This difference influences the different manners of application for these two products.
Warm springs and summers cause peaks in the greenhouse climate. Possible consequences are: reduced photosynthesis, delay in plant growth, loss of quality and lower production. You can prevent this with the right shading agent.
