Lettuce grower FromBoer is taking a major step forward with the construction of a new 7-hectare greenhouse in Dinteloord. Both the greenhouse concept and the screen installation are innovative. Whilst the lettuce is growing, the greenhouse is forbidden territory. PDI therefore supplied a sturdy installation (double screen), which requires little to no maintenance. The Slip-in system allows the screen cloths to be installed and replaced quickly and safely. There is also a safety device that immediately sounds an alert should anything go wrong with the screen.
