This report presents the development of a peat-free seed germination pod utilizing Typha-based soilless media. In collaboration with Typha Co., the project builds on prior research done by the 2024 Typha capstone team on optimizing Typha-based growing media. The objective of this project is to provide a sustainable alternative to peat-based seed germinations pods within the commercial floriculture industry.

The project focused on improving the Typha-based media by incorporating soil amendments including perlite, pine fibre, and biochar. A six-week growth trial of petunia seedlings was conducted in a hydroponic wall system to assess the impact of these amendments on plant growth. Twelve different compositions of amended Typha-based media were tested against conventional growth substrates. Additionally, 11 technical specifications were identified to evaluate how the chemical and physical properties of amended Typha-based media compare to those of peat. Primary technical specifications include water holding capacity, nitrogen immobilization, and pH. The research also investigated the feasibility of forming Typha-based media into seed germination pods by application of a binding agent. Agar, yucca powder, molasses, and flaxseed mucilage were tested as binding agents during seed pod design. Binder performance was evaluated by structural integrity, impact resistance, and rehydration properties of the seed pod to ensure durability during transportation and usability in greenhouse settings.

Growth trials showed that [REDACTED]. Further testing for the manufacturing process is recommended.

By leveraging Typha’s nutrient retention and release properties, this project provides a sustainable media alternative for floriculture consumers, while also contributing to the ecological restoration of Lake Winnipeg. The development of a cost-effective solution has the potential for wide-scale adoption, reducing reliance on peat and its environmental impact. This approach aligns with the growing demand for sustainable agricultural practices, offering both environmental and economic benefits.
