We describe here how to seed them in our chainpots.

We also have detailed video on our YouTube channel. Visit and check it out!

  • Seeder: 3.3mm Diameter × 2mm Thickness (2-3 naked seeds per cell)
  • Nursery tray

  3. Remove the rods and set the frame to the nursery tray.
  4. Fill the potting soil with hands.
  5. Clean the surface with the brush.
  6. Make holes with the dibble board.
