Chalking has been a familiar method for light and temperature management in poly greenhouses for a long time. But what if you could take your greenhouse climate strategy much further? Movable screens are the perfect addition to or substitute for chalk. These screens give growers full control over light, temperature, and humidity, leading to up to 25% more crop yield, according to recent scientific research by Wageningen University & Research! They also offer additional benefits, such as:

1. Greater flexibility and control under all circumstances.
2. 30% more PAR light, allowing crops to make optimal use of growth light.
3. Lower energy costs, thanks to heat retention in the early season.
4. Crops become more resilient and less prone to diseases.
5. Up to 25% higher crop yield thanks to an optimal greenhouse climate.
