User experiences show minimal wear off on the apex of the roof with the use of Q4 White. It is very important to shade the top of the greenhouse because the sunlight shines from early morning until late in the evening. The apex of the greenhouse roof is also most vulnerable to rain, hail and wind. The wear off on the apex is minimal with Q4 White. Many growers consider that a very good and desirable property of Q4 White.

With Q4 White it is possible to choose the most optimal shading percentage per crop. You can choose the right shading percentage by diluting the appropriate amount. The graph shows the shading percentage relative to the number of buckets per hectare of Q4 White.
|Buckets per ha||Shading||Lifespan (weeks)+/-||Weather resistance|
|34||80%||24 - 25||Maximum|
|25||75%||22 - 24||Maximum|
|20||65%||17 - 21||Maximum|
|16||55%||13 - 16||Maximum|

Usage Q4 White
Calculate the number of buckets needed by reading the desired percentage from the table above. Add the shading agent to clean water while stirring. Use enough spraying liquid to evenly divide Q4 White on the roof of the greenhouse. The amount of spraying liquid needed for your roof depends on the manner of application. Use 1.200 to 1.400 liters per hectare when the shading agent is applied mechanically. When the choice for manual application has been made, we recommend to use 1.500 to 1.700 liters per hectare.
We advise to stir the solution during the process of application. Apply Q4 White on a dry and clean surface.
Q4 White can be removed from the greenhouse easly pand safely at any moment with Removit. Some rain will wash off Q4 White after applying Removit in the right dosage. Q4 White also can be washed off manually if it does not rain for a long time.
Do not use Q4 White in combination with other shading products. Prevent the product from entering the basin during application or removal. Store frost free.
