Why is it important to clean your greenhouse roofs?

The success of your crops starts with maximizing light penetration into the greenhouse. Dirt and dust accumulate on the roof films, blocking essential light and leading to yield reduction. Studies show that every 1% loss in light transmission results in a 1% decrease in agricultural yield. Therefore, keeping the greenhouse roof clean is a direct investment in your profitability.

What are the main challenges?

  • Accumulation of dust and dirt throughout different seasons.
  • Difficulty reaching high spots for thorough cleaning.
  • Natural wear and tear of the films, reducing light penetration over time.

The solution – Proper periodic cleaning!
✅ Periodic inspection of light transmission (PAR) – If the level is low, it's time for cleaning.
✅ Gentle washing with clean water – Avoid abrasive substances that could damage the films.
✅ Using an extended aluminum pipe – Helps reach high areas with ease.
✅ Cleaning according to the type of crop and greenhouse location – For example, tomato cultivation in Galilee or rose exports in Colombia require different treatments.

Conclusion
Cleaning greenhouse roofs might seem like a complex task, but its impact on yield and profitability is significant. Changing habits is not always easy, but this small investment will pay off with improved and high-quality produce.
