BLV Sponsor Presentation - The Interaction of Light, Temperature and Humidity

Light, temperature and humidity always go together. There is a strong link between light, temperature and humidity. On the one hand side lighting has a significant effect on the leaf temperature, humidity and the transpiration rate, on the other hand, temperature and humidity influence photosynthesis and growth. Therefore, lighting should be seen as an integral part of the greenhouse climate. In this presentation I will show how light interacts with temperature and humidity; and I will reveal how this knowledge can be used to regulated plant growth and how it can be used to avoid growth of plant pathogens.

A Greenhouse Lighting Primer: What, When, and How

Whether you’re already using photoperiodic or supplemental lighting or are looking into incorporating it into your greenhouse operation, you’ll want to understand the basics of lighting and the options that are available to you. What are the differences between photoperiodic and supplemental light? What types of lighting are best for which situations? How do you determine how much light you need? Christopher will answer these questions and more.

PARSource Sponsor Presentation - An Overview of Lighting Layouts

A well-planned and scientifically sound lighting layout is critical for excellent results in the grow room or greenhouse. The proximity of lighting fixtures to each other and to the plant canopy, as well as the structure of the lighting array within the room's dimensions, are extremely important factors to consider for any horticulturist who hopes to maximize yield by carefully designing the growing conditions. We will explain in detail how lighting layouts calculate factors like greenhouse/room design and size, crop light needs, and regional light conditions to create a unique layout that meets the grower's specific lighting objectives.

Shedding the Light on Crop-specific Daily Light Integral Requirements

We are all aware of how the cumulative amount of light a plant receives over the course of a day or daily light integral (DLI) can have on growth, yield, and quality of our greenhouse crops. However, do you know what the recommended DLIs are for producing high-quality plugs, liners, annuals and perennials, vegetables and leafy greens? Roberto will shed light on crop-specific DLI requirements that have been established from years of research.

Heliospectra Sponsor Presentation - Controlling Production with Dynamic Light Response

Growers are in a constant quandary over supplemental light use. Typical HPS and LED systems don’t give operations teams the flexibility needed to use light strategically or incrementally. Dynamic, DLI-controlled LED lighting solutions change this. Heliospectra shows you how to build a business case that will push production and profits higher every month. Using natural sunlight and dynamic supplemental light response, you can create perfect light conditions in your greenhouse 365 days a year.

The Economics of Supplemental Lighting
Is adding supplemental lighting to your greenhouse operation economically feasible? Ricardo will walk growers through how to estimate the cost of running supplemental lighting and determine in which situations it makes the most financial sense.
