Maximising light levels is always a top priority in vegetable production. And even if a crop can manage without a screening system, light interception has to be kept to a minimum. To respond to this, Holland Scherming has developed a unique spring system: Smart Spring, the ideal connection between the profile and the pull wire.
The procedure is simple but ingenious. The Smart Spring moves in two directions, so the system pulls the package against the truss under tension. Unlike a conventional slip block, there is no loss of resilience over time. This results in minimal light interception – particularly useful for crops for which screen packages are measured in centimetres. For example, a 2 cm smaller package reduces light interception by around 40 m2 per hectare.
