Synergies between dehumidification and hermetic screens As energy prices continue to fluctuate and sustainability targets tighten, greenhouse growers are increasingly turning to advanced climate‑control technologies to reduce energy consumption. This article highlights two of these technologies — modern dehumidification systems and hermetic screens — and how they work together to create a more stable, energy efficient greenhouse climate.
A uniform climate reduces the risk of condensation on crops, enabling growers to operate at higher humidity levels and by doing this lowering plant transpiration and overall energy demand." © Phormium nv Proven in practice Tomato nursery Pijl LV in Belgium has been pioneering this approach for over 15 years. "Combining a hermetic screen with our dehumidification system still yields the best results," says grower Wim Pijl, who recently upgraded to a new Hermetic Clear screen in anticipation of rising energy‑efficiency demands.
Why this matters: This matters when it gives operators a clearer way to manage water, nutrients, and root-zone risk. That kind of control usually improves both resource efficiency and crop consistency.
Frequently Asked Questions
What should growers evaluate before changing a lighting strategy?
They should look at crop type, canopy structure, current light distribution, energy cost, expected yield gain, and whether the new strategy improves whole-canopy efficiency.
Why is light distribution often as important as light quantity?
Because adding more photons to already saturated leaves does less work than improving how light reaches the parts of the canopy that are still underperforming.
