In 1947, the MSPB purchased an isolated farm in Masardis, Maine, now known as the Porter Seed Farm, enabling it to better control and manage the production and quality of foundation seed stock. This facility is equipped with tissue culture production, disease testing laboratories, seed storages with climate control systems, greenhouses, and an irrigation system, to support the production of nuclear and foundation seed.
In 2009, the Maine Seed Potato Board began producing minitubers in a new state-of-the-art greenhouse using hydroponics.
The MSPB facility provides tubers grown in vitro (microtubers), greenhouse grown tubers (minitubers) and transplants, and foundation seed to seed growers. Seed may be purchased as minitubers (MT), field-grown for one year (FG1), and field-grown for two years (FG2).
