Ladbrooke Soil Blocker Insert Pins - 3/4" Cubic Pins (Set of 4)

Use insert pins with the 2" Soil Blocker, 20 Block or the 12 Block Professional Floor Blockers (not the Mini-Blocker or the 4" Soil Blocker). Makes indentations in larger blocks to accept smaller blocks or seeds and cuttings. Cubic Pins are used for large seeds or blocks made for the Mini Blocker. 5/8" Seed Pins make an indentation for seeds. 1" Dowel Pins makes a deeper hole for cuttings or large seeds. A great source of information on how to use soil blockers is the Soil Blocker Booklet by David Tresemer.
