Give your drop seeder more versatility with an interchangeable plate with 2.8mm diameter holes.
The seed plate easily removes from the drop seeder unit and can be swapped on the fly in seconds.
This seed plate has 2.8mm holes designed for smaller seeds such as mizuna, scallions, kale, shallots, turnips, and some greens.
When using with kale you will have about 1-2 seeds per hole and will drop 1.2g of seed.
Radish seed may work, but based on our trials most radish seed is too large for these holes.
Tiny seeds like amaranth will work in the seeder, but based on our trials static electricity creates some issues, so with tiny seeds like amaranth it may be easier to seed by hand if you are doing multiple flats for microgreens.
Note: This seed plate will only fit into this 4.5mm Drop Seeder Unit that we sell. It will not fit into the 2.8mm drop seeder which was previously sold a la carte. And it probably will not fit into seeders made and/or sold by other companies.
