Spuitkrijt

Spuitkrijt is a powdered shading agent that is mixed with water and sprayed onto the greenhouse roof. It consists of 100% calcium carbonate and contains no adhesive components. As a result, it remains on the glass temporarily but is largely washed away by the first rainfall.

Application and Use of Spuitkrijt

Spuitkrijt is mainly used:

  • Immediately after planting young crops
  • During short periods of hot weather
  • As a temporary additional layer on top of La Blanche or Witvast when extra shading is suddenly required

Mixing Ratio and Coverage

  • 1 kg of Spuitkrijt per 4 litres of water
  • 1 bag (25 kg) per 100 litres of water
  • Coverage: approximately 500–700 m² per bag (depending on the spraying technique and desired layer thickness)
