About Prairie Plant Systems Inc

Growth Chambers

Growth Rate Comparison Plant production in a biosecure underground growth chamber, particularly C3 plants exhibit a dramatic increase in growth, without altering the basic phytochemical profile. This allows for the efficient use of research and development funds by reducing the costs associated with regulatory approvals for genetic containment in the early stages of biopharmaceutical development.

Prairie Plant Systems is leading the industry with a robust research and development program that has to date completed research on more than 500 plant species within the biosecure growth chamber environment, including various softwood and hardwood species, culinary herbs, nutraceuticals, ornamentals and agricultural crops. Examples include species of Nicotiana, Taxus, Maize, Brassica, Populus, Echinacea, and Ocimum.

Leveraging strict genetic containment and environmental control are the benefits of developing plant-made pharmaceuticals within the bioseceure growth chamber environment.

Prairie Plant Systems has two biosecure growth facilities, one above-ground location in Saskatoon, Saskatchewan, and a second underground facility, SubTerra LLC, in White Pine, Michigan.

The Canadian facility is focused primarily on the research, development and commercialization of medical cannabis under the Marihuana for Medical Purposes Regulations (MMPR) governed by Health Canada. To learn more visit our CanniMed page.

SubTerra LLC is home to the research, cultivation and processing of biopharmaceutical plant species with several industry collaborators, including a contract for the growth, production and harvest of transgenic tobacco seed used in cancer research. Click here to learn more about SubTerra.

Advantages of Biosecure Growth Chambers


Genetic and Physical Security

  • Germplasm containment.
  • Ensures protection of proprietary technology and intellectual property from sabotage or competitive surveillance.
Lab Tech

Quality Assurance/Control

  • GAP and GLP compliance – growth chamber.
  • cGMP compliance – bioprocessing.
BGC Corn

No Insects/Weeds = No Pesticides/Herbicides

  • BGC is relatively disease/pest free.
  • Completely isolated from the outside environment.
Growth Chamber

Year-Round Environmental Control

  • Computer monitored to provide 24/7 environmental control.
  • Accelerated growth.
  • Shorter growth cycle results in faster research and development feedback.
Lab Tech 2

From Lab to Commercial Production

  • Biotherapeutic proteins.
  • Rare and important phytochemical compounds.

Prairie Plant Systems has grown significantly through development and acquisition of our key subsidiary companies:

CanniMed Ltd.

CanniMed Ltd. was established in 2013 to provide Canadian patients with access to a standardized and trusted supply of pharmaceutical-grade cannabis under the Marihuana for Medical Purposes Regulations (MMPR) governed by Health Canada.

SubTerra LLC

Sub Terra LLC is a plant-based pharmaceutical manufacturer committed to the production of Active Pharmaceutical Ingredients (APIs) such as high value proteins and phytochemicals.

PPS Fruit Trees

Decades of research and development have made PPS a leading supplier of fruit trees to orchards around the world. Our continued commitment to excellence can be seen in the uncompromising quality of every plant PPS grows and sells.
