Welcome and Introduction
Tracking the Horticultural SSL Market and Technology
Speakers: Philip Smallwood, Research Director, Strategies Unlimited
The market for horticultural lighting is undergoing a renaissance of sorts. Not only are advancements in LED lighting for horticulture changing the way we grow our crops, but they are also advancing our understanding of how crops utilize light and have the potential to revolutionize the industry in its entirety.
Philip will share data and insights from Strategy Unlimited’s most recent research report “The World Market for Horticulture Lighting”, focusing on the impact LED lighting is having on the industry and the main drivers behind the market’s growth, with an emphasis on the cannabis market in North America.
The Impact of LED lighting on Floriculture and Greenhouse Crops
Speakers: Steven E. Newman Colorado State University
Light-emitting diodes (LEDs) are rapidly becoming the light source of choice for greenhouse and indoor lighting for plant growth due to their relatively high electricity to light energy conversion, targeted spectra, low operating temperature, long life and solid-state construction. The migration from incandescent to fluorescent to high intensity discharge (HID) halogen, to high-pressure sodium (HPS) to LED has taken time; however, with renewed interest in energy conservation and novel production is fueling a rapid growth in LED technology. Colorado State University has moved into a new state of the art research and teaching greenhouse. These new greenhouses are complete with LED lighting technologies through a partnership with Philips Horticulture LED Solutions. LED light research at CSU includes bedding plant plug production, rooting studies, hops, lettuce, and strawberries. The presentation will include highlights of projects underway at CSU and from other universities active with LED light research for plant growth.
Session 1: Science, Standards, and Market Transformation
Speaking Plant: Language of Horticultural Metrics, Test Methods, and Standards
Speakers: Austin Gelder, Lighting Performance Technical Advisor, UL
Photometric terms like Lumens, CRI and CCT have no place in plant growth lighting, because plants don’t have eyes. In order to adequately describe the lighting needs of plants and objectively compare performance of horticultural lighting products, a whole new vocabulary is needed, and has little in common with those from traditional lighting. This session will cover applicable metrics (such as PAR, UV, IR, µmol/J, and DLI), standards, and test methods for horticultural lighting, considerations for testing, and what is upcoming and in development for horticultural lighting.
Horticultural lighting promises to transform farming with tremendous potential for crop turnover and yield. However, new energy loads from lighting and HVAC could have significant impacts on the electric grid. DLC is developing performance requirements for horticultural lighting products to push product performance while minimizing the energy impact of these technologies. This session will provide background on utility motivations and provide an overview of DLC’s efforts.
Speakers: Kyle Hemmi - Senior Energy Engineer CLEAResult
With common metrics, test methods, standards, and performance specifications for horticulture lighting coming together and electrical demand for horticulture facilities ballooning in certain regions, more utilities are expected to take aim at these applications through their energy efficiency programs and rebates. Join the speaker as he walks us through some examples of what utility programs have done in the horticulture space to date and how those efforts are likely to accelerate and morph over time given standardization efforts, continued technological and scientific advancement and increasing market opportunities.
Session 2: Projects/Case Studies
The Myriad Ways That UV LEDs Will Impact Society Through Horticultural Lighting
Speakers: Dr Peter Barber III - Director of Product Marketing & Business Development Seoul Semiconductor
Dr. Peter Barber will discuss use cases for UV LED from the seed to the table. The use of UVA, UVB and UVC LEDs has a positive impact on the Horticulture ecosystem. Dr. Barber will touch on a broad range of topics including strengthening root systems, improving crop yield, prevention of mold and bacteria, increasing nutritional/medicinal value in plants, promoting flowering, disinfecting/cleaning hydroponic systems, increased shelf-life, and order elimination.
Dynamic LED Lighting for Precision Crop Control
Speakers: Melanie Yelton - VP of Research LumiGrow
Decades of research and investigation have led to an understanding of how plants perceive specific wavelengths of light. We now understand that LED light can be used to improve plant quality and control morphology, growth rates, and other characteristics.
Using dynamic LED fixtures as a precision tool for crop production, growers are now adjusting their lighting strategy to fit the needs of their crop. As simple lighting becomes “Smart Lighting”, luminaires will provide a largely automated solution for addressing plant’s needs and creating greater crop consistency.
Join Melanie Yelton as she explores the potential of dynamic LED fixtures. We will use vine crops as a case study for LED light’s potential for precision crop control, and delve the state of today’s smart horticultural lighting, including new LumiGrow light sensor technology.
Capturing Sun Patterns and Using Software Tools for Horticultural Lighting
Speakers: Ian Ashdown, President, Suntracker Technologies
Horticultural lighting poses unique problems for professional lighting designers. Simply put, today’s lighting design software is ill-suited to the task of designing lighting systems for greenhouses and vertical farms. One problem is that existing photometric data formats are based on photopic lumens and human observers. Plants respond to the spectral power distributions (SPDs) of light sources very differently. But the problem runs deeper. Efficient algorithms to perform necessary daylighting calculations, including bidirectional transmittance distribution functions (BTDFs) for diffusing materials, have only recently been developed. This presentation will describe how software tools can be used in horticulture, for instance to model spectral irradiance at the plant canopy, with a spectral range of 280 nm to 800 nm. Moreover the talk will describe how intracanopy lighting design may require modeling three-dimensional light distributions within the crop rather than just at the crop canopy.
Session 3: Lighting Technologies and Advancements
Horticulture LED Fundamentals
Speakers: Kurt Liepmann Applications Engineer, OSRAM Opto Semiconductors
It is well known that LED technology can offer numerous benefits over traditional lighting sources for horticulture lighting applications. In order to fully utilize these advantages, it is important to understand the various performance characteristics of LEDs. This presentation will take a deeper dive into each of these characteristics including, LED binning and characterization, typical photon flux and efficacy ranges, and performance curves for the various wavelength/color offerings typically used in horticulture applications.

SSL Limbo- Assumptions and Opportunities in Horticultural Light Recipe Management
Speakers: Brian Gandy - Founder Sustainable Terrains
Claims of eighty percent power savings and unprecedented growth from dual spectrum grow lights are becoming a thing of a marketed past as we proceed into and industrial future with the technology. As the dust settles and the science emerges as a more than just feasible technology for Horticulture, the potential for plant manipulation and production using certain wavelengths is still an emergent technology. Beyond the claims of companies, what is currently accepted and what is next to be validated in SSL Horticulture from "Blurple" to Full Spectrum and from Plant to Personal Protection, I will address the current state and immediate as well as long term potential of spectral formulation and to full cycle lighting recipes using know morphological responses and introducing some that are assumed yet still next to be proven.

Closing Plenary – Fast-forwarding the Future of Food
Speakers: Tessa Pocock PhD - Senior Research Scientist at Center for Lighting Enabled Systems and Applications. Rensselaer Polytechnic Institute.
Recent advances in solid state lighting technology are enabling the development of ‘designer’ crops through the knowledge of plant physiological and biochemical processes. Myths about what light plants need abound on the internet and part of this seminar will debunk and explain many of these misconceptions. The latest evidence about crop specificity and lighting will be presented to help guide the audience through the very complex maze plant-light interactions. Lastly, plant production whether it be for food, nutrition or pharmaceuticals will be enhanced through automation and sensing technologies. Mechanical automation is already in use in modern controlled environment agriculture facilities. LESA has developed a new sensor that remotely detects the physiological state of the crop as well as pigmentation and growth. The latest data from our sensing system will be presented with focus on potential applications for fast-forwarding food production.
