Exclusive! This is the first drop seeder for soil blocks! And the first to use magnetic springs! 

The simplicity is the beauty of this design. Plates are quickly interchangeable yet held firmly by neodymium magnets. No grooves for the seed and dirt to get caught. Also no binding or breaking of plates that get wedged at in angle like in other models. Also there are not screws, adjustments, or moving parts.  For use with the Mini-35 Handheld Soil Blocker from Ladbrooke.

This set comes with a standard base plate and 4 interchangeable top plates  with seed hold diameters of the following sizes:

• 2.8mm
• 3.5mm
• 4.5mm
• 6.0mm
