The primary purpose of the drop seeder is to seed paperchain pots. Farmers who purchase the drop seeder for this purpose get the secondary benefit of being able to use the drop seeder for microgreens.
Please read this post carefully before purchasing the drop seeder only for microgreens.
While we don’t recommend using the drop seeder for microgreens at scale, it will work.
Why don’t we recommend it?
- Static. The drop seeder plates are made from acrylic plastic and small seeds tend to stick to the plates due to static. Based on our experience small seeds like amaranth and basil are not practical for the drop seeder due to static.
- Multiple Drops. Some crops require up to three drops to get enough seed on the tray. Is it faster to do three drops of the drop seeder than to seed by hand? Probably not.
- Seeds Between the Plates. This tends to only be an issue for smaller seeds, but seeds can get stuck between the drop seeder plates if you are seeding a lot of flats. When this happens you have to stop seeding, remove the top plate, and clean out the drop seeder. This takes time.
These three issues make us question whether the drop seeder is a time saver for microgreens compared to seeding by hand.
While the drop seeder may or may not be slower, the biggest advantage of the drop seeder for microgreens is that it distributes the seed evenly on the soil surface eliminating potential fungal issues.
Please think about these factors and what crops you are going to grow before you purchase a drop seeder to use exclusively for microgreens.
If you are going to use the drop seeder for microgreens, here is a chart to help determine which seed plates to use:
When you are growing microgreens, sometimes the flats can stick together. Here is a way to troubleshoot that:
