Germination Standards

At OSC Seeds, our germination standards are the most rigorous in the world — not only do we test all our seeds on a regular basis, we are required by Agriculture and Agri-Food Canada to have our seeds tested at government authorized labs to ensure that they meet or exceed Canadian Seed standards.

Additionally, we are monitored by Agriculture and Agri-Food Canada Inspectors throughout the season to ensure we continue to meet their strict requirements.

Seed Counts

The majority of our seed is packaged by machine. Some specialty varieties are machine-counted and packaged.

For all our vegetable seeds, you will see a line that states the number of ‘seeds per gram’ for that variety. Most bulk packages are sold by weight.

The ‘seed per gram’ measurement is an approximation, so please keep in mind that as seeds age they gradually lose moisture and this can affect the package weight.

Some hybrid varieties are sold by the seed count. This information is stated in our paper and online catalogues.
