Winstrip and 1020 flat 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. This seeding system works best with round, uniform seeds although it can be used with seed as irregular in shape as beet and chard seed. Tiny seed is not compatible with this seeding system.

Standard seed plate 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 3.5to 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.

We can make custom plates with any hole size, just call and let us know what you need!

NOTE: the seeder does not handle tiny seed well. Tiny seed can get caught between the two layers of plastic.
