Title : Grasses in hydroponics: Oats and Barley


Controlled Environment Agriculture has emerged as a fundamental pillar of the primary-level food production industry. Getting desirable results in controlled environments depends on efficiently manipulating and managing the factors that directly or indirectly interact with the plants. Thus, this study aims to determine the effect of different LED wavelengths on Oats and Barley while also determining the performance of a novel hydroponic substrate, permeable concrete in supporting plant growth in greenhouse conditions. This research investigated the plant-light response of 3 LED light treatments; Narrow Amber+ 430nm, 5000k + Wide Amber and Narrow Amber +430nm +485nm and additional treatment under natural sunlight Plant-light response and a comparison between the hydroponic substrates was measured based on data acquired on plant growth rate over 45 days in the hydroponic setup. In addition, data on fresh and dry biomass production was investigated at the time of harvest. The preliminary results showed 5000k + Wide Amber showed 25% better results than both single and double narrow amber standing close to each other, quantitatively followed by the natural light treatments in terms of increased plant growth rate. The future implications of this research will allow to enumerate the potential edible yield under the same conditions that will have commercial significance in selecting the optimum artificial light sources under controlled environments.

Audience Take Away:
Explain how the audience will be able to use what they learn?

  • Audience can also expect to learn about the impact of artificial lighting, particularly optimized LED wavelengths, on the growth of plants in controlled environments.
  • Apply efficient LED lighting techniques to improve plant growth and productivity in controlled environment agriculture systems.
  • Utilize the discovered information to enhance the design and administration of controlled environment agriculture systems, which may result in increased yields and the adoption of more sustainable practices.
  • The presentation will also discuss the novel material called Biocompatible porous concrete which unlike conventional concrete has a lower pH, thus allowing plant germination and growth.

    How will this help the audience in their job? Is this research that other faculty could use to expand their research or teaching? Does this provide a practical solution to a problem that could simplify or make a designer’s job more efficient? Will it improve the accuracy of a design, or provide new information to assist in a design problem? List all other benefits.

    This research provides practical solutions and valuable insights that can streamline and enhance the effectiveness of designing and managing controlled environment agriculture systems. This information can be utilized to enhance their own research or teaching curriculum by integrating the most recent advancements in artificial lighting. Furthermore, researchers and practitioners in the field of agriculture can gain advantages from enhanced precision in creating ideal growing conditions, ultimately resulting in higher productivity and profitability in greenhouse environments.

    Biocompatible porous concrete can also be used as a plant growth substrate in urban environments where growing spaces are limited. Its potential for germination and growth of different kinds of plants can be explored.


Jasmine is presently in her second year of her master’s degree in Bioresource Engineering (Thesis) program at the McGill University and currently working under Dr. Mark Lefsrud’s supervision. She completed her bachelor’s in agriculture (Hons.) from Punjab Agricultural University, Punjab, India in 2022. Her research is centered around controlled environment agriculture, biomass production, and the development of biocompatible porous concrete.
