Set of 90 assorted tips for Gro Mor Wand Seeder. Set is comprised of 18 each of five different tip sizes. All tips are made of a polyethylene material to give good service. These tips are easily replaced when needed. If a blockage occurs in a tip, remove that tip from the wand and place it over one the openings of the exhaust muffler of the vacuum pump while it is running or use a low pressure air source. This will clear the blockage. Return the tip to the wand and continue seeding.
