Gravity Seeder innovation extended to allow seeding of non-chain paper pots! This design originated in Japan with the paper chain pot system. The seed tray bottom has large holes and the seed tray insert has smaller holes. At rest, the holes in the insert do not line up with the holes in the bottom of the tray. This allows you to shake seed into each smaller hole. With a squeeze of your fingers, the insert lines up with the holes in the bottom of the tray and the seeds drop into each cell. For a video of this type of seeder in action, see our gallery page.

This seeder was originally designed in Japan, where virtually all commercial vegetable seed is available in pelleted form. It works best with round or 'roundish' seed. It can work for alliums, pelleted lettuce, beets, spinach, cilantro, brassica (cabbage family) crops, and other round/roundish seed.

Seed plates are available with different hole sizes depending on the size seed you are planting. If you plant many different kinds of seeds, you will need several different seed plates. We offer several standard sizes but can make seed plates with virtually any hole size (up to 8mm) based on your particular needs.

The following are the standard seeder insert hole sizes:

2.0mm to 2.5mm. These are the smallest practical hole size for small seed, including brassicas

2.8mm: Recommended for alliums, larger-seeded brassicas and other small seed.

4.0mm: Recommended for pelleted lettuce, small-seeded varieties of spinach and beets, cilantro, and other seed that is approximately 3.5 to 3.9mm in size.

4.5mm: Some growers of pelleted lettuce prefer a 4.5mm hole over the 4.0mm hole. Will also work for many varieties of spinach and beets.

5.0mm: Recommended for larger seeder varieties of spinach and beets, seeding alliums in bunches.

NOTE: The seeder does not handle tiny seed well. Tiny seed can get caught between the two layers of plastic. Made in Wisconsin, USA. We are proud to be helping to create jobs in our local community!
