Drop Seeder—Trays & Plates Compatibility Charts
The drop seeder ships with a bottom plate and top tray already installed. That pairing has 3 mm holes and sows in a 72-cell soil-block pattern.
- To switch seed size but keep the same pattern, swap only the top tray.
- To switch to a different pattern, swap both the bottom plate and the top tray.
