| Subterra's parent company, Prairie Plant Systems, established in 1988, began working with underground growth chambers in 1991. After past and current successes with their chambers in Flin Flon, Manitoba, Canada, Prairie Plant looked to possible ventures in the United States, leading them to the closing White Pine Mine in Michigan. |
| Prairie Plants growth chamber is located in one of the Hudson Bay Mining and Smelting's existing zinc mines. For more information on Prairie Plant Systems, please visit their site, at: www.prairieplant.com |
