Triple proof of the effectiveness of Limex crate cleaning in horticulture


Every successful growing season starts long before the first plant enters the greenhouse. We take a fresh look at cultivation hygiene: not as an extra step, but as the beating heart of your system.

In three short videos, you’ll discover how our method gives you maximum control over your harvest results:


1. Our method: how we ensure reliable crop hygiene


Crates and trays form the backbone of logistics in horticulture. They transport plants, vegetables, and propagation materials throughout the entire chain. Precisely for that reason, they can also become a critical carrier of contamination.

That is our starting point: every link you bring under hygienic control reduces risk in cultivation.

By structurally keeping logistical carriers clean, you work towards:

  • higher yields from the same input
  • less dependence on chemical crop protection
  • reduced loss and waste in the chain
  • safe reuse of materials
  • improved food safety
  • longer shelf life
  • lower disease pressure in the cultivation system

The logical question then is: how do we know this actually works? We demonstrate this in independent research in the next section.

2. Independent research: proven effectiveness of our cleaning method in the lab


Together with an independent laboratory, Normec Groen Agro Control, we investigated how effective different cleaning and disinfection methods are on crates and trays.

This research focused on:

  • spread of pathogens via logistical carriers
  • effectiveness of different cleaning strategies
  • removal of bacteria, fungi, and viruses
  • measurable reduction of contamination pressure

Pathogens such as Fusarium and ToBRFV were deliberately included due to their impact on the sector. As independent researcher Michel Witmer states: “Limex has ensured that they have very good cleaning and disinfection. It has been proven with our test that the virus was no longer present after cleaning. For growers, it means trust, the fact that the crates are clean.”

How does this translate into daily practice? Growers show this themselves in the next video.

3. Practical experience: what our washing machines mean for growers’ daily operations


In practice, everything revolves around continuity, reliability, and predictability. Our customers experience every day what a stable cleaning process means for their operations.

Scientific validation is important, but ultimately what happens on the shop floor is what counts. As Peter van Geest, Technical Service Coordinator at the former RedStar, explains:

“Thorough hygiene is very important to RedStar. Not only for food safety, but also for the spread of diseases to our gardens. The tomato virus, you really don’t want that in your garden.”

When crates move multiple times a day between greenhouse, processing, and distribution, reliable cleaning is essential. Customers experience benefits such as lower disease pressure, greater process stability, and increased confidence in clean starting material.

Grow with confidence and control over your hygiene

At Limex, we believe that strong cultivation starts with control before risks arise.

With our washing lines, we create a controlled, continuous flow of clean crates and trays. This reduces contamination risks and strengthens the continuity of your process.

You are not just choosing a machine, but a proven method that pays itself back in stability and growth.
