Lighting Tip

Bench and Bed Layout is Important

Most light plans focus on average light levels and acceptable uniformity in the greenhouse. These figures can change significantly based on the spacing between lights and distance of the lights from the plant canopy. If general information such as width and length of the greenhouse is the only information provided to the designer, you may receive varying light plans and results.

To help develop proper lighting plans, it is important that you include the bench or bed layout. Providing a bench or bed layout enables the lighting designer to concentrate the light on the essential growing areas rather than wide center walkways or work areas in the back of the greenhouse. The information needs to provide other details such a bench orientation or distance from the walls or aisle space as these details can vary design calculations and results.

More importantly, if a detailed layout includes a bench or bed design, it can save the grower money. These savings can be achieved by improving light uniformity resulting in consistent growth of your plants and in most cases you will see a reduction in the number of fixtures for your project.
