Online educational course

Controlling the indoor environment increases efficiency

The growing environment in greenhouses and indoor farms has a profound effect on numerous crop quality attributes, including: crop yield, consistency, growth rate, flowering, and disease.

In this 6-week modular course, learn about all aspects of climate controls in greenhouses and indoor farms. Modules will focus on lighting, temperature, carbon dioxide concentration, humidity and VPD, irrigation, and autonomous controls.

Industry experts will define the specific environmental requirements of plants, show how climate controls work to improve yields in real-life case studies, and supply interactive demonstrations using commercially-available climate control technology. By the end of this virtual course, participants will be able to make informed decisions about selecting and using climate controls in their growing operations.

Live Sessions

Join each 2-hour module live to participate in Question & Answer sessions with industry experts.


Watch recordings on-demand for 4 weeks after the end of the course, or enjoy unlimited access to recordings with an annual GLASE membership.

Course Content

Module 1

Plant Lighting Control Systems

Supplemental lighting systems are used in commercial CEA facilities to optimize consistent production year-round, increase crop quality, and control flowering of photoperiodic crops. Learn how the development of new lighting controls and technologies have provided growers options to increase energy use efficiency and reduce the cost of supplemental lighting.

Thursday January 19


Module 2

Temperature Control Systems

Temperature affects numerous crop quality attributes, including growth rate, plant development, and plant extension. Controlling the temperature of a greenhouse or indoor farm can also be a major factor in facility energy costs. Learn how efficient temperature sensors and controls can improve crop production and reduce operation costs.

Module 3

Humidity Control Systems and VPD

Humidity is one of the most difficult aspects of a greenhouse climate to regulate. Temperature and air pressure, along with vapor pressure deficit (VPD) and plant transpiration, influence the humidity of the air. Plant diseases, stress, and growth rate all depend on humidity. Learn the intricacies of controlling this fluctuating measurement in your climate to better control plant growth and health.

Module 4

Carbon Dioxide Control Systems

Carbon dioxide (CO2) is an essential component of plant photosynthesis. Increasing CO2 concentrations in a greenhouse inproves fruit yield, flowering, and plant strength, but controling CO2 can prove difficult in greenhouses that require venting. Learn about available technology to measure and control CO2 concentrations in your greenhouse.

Thursday February 9



Module 5

Irrigation Control Systems

Receiving the right amount of water is vital to the survival of all plants. In greenhouses and indoor farms, growers must provide water directly to crops, as rainwater is unavailable. Learn about different systems of greenhouse irrigation and how to control exactly how much water plants receive.

Module 6

Autonomous Control Systems

Precision in agriculture leads to better profits, less labor, and higher efficiency. All aspects of climate control, from lighting, temperature, and humidity, to CO2 and irrigation can be controlled autonomously using integrated technology. Learn about autonomous technologies for greenhouses and how growers are using them in real operations.
