effectivity + efficiency + reliability
The main advantage of horticulture LED lighting (or digital lighting) is the ability to fine-tune the intensity as well as the spectral distribution (spectrum) of the emitted light. Fine-tuning of intensity allows to increase the effectivity of the light by reducing stress. Fine-tuning of the spectrum also allows to increase the effectivity of the light and furthermore to deliberately trigger important processes within the plant. The combination of both features will lead to increased yields and crop quality, reduced production time and a more cost-efficient production process.
In order to develop sophisticated lighting recipes all the other environmental parameters (temperature, CO2, RH and watering/fertilization profiles) have to be considered as well. The development of lighting recipes should be an essential process of any professional business operation. Parallelization will help to save time and money.
For detailed information we recommend the book LED Lighting for Urban Agriculture.
In order to be competitive a professional lighting design is crucial. Efficiency is important, but effectivity is what matters most. To optimize effectivity a holistic approach is inevitable.
Beside the lighting metrics aspects like business model and strategy, cultivation method, technical framework conditions (like HVAC) and last but not least the total cost of ownership and ROI have to be considered.
