| These Grodan Metal Needles are used by professional growers to extract water samples deep from within a Gro-Block or Gro-Slab. They make a smooth insertion with little damage to the block or slab. Use with any Luer-Lock™ Syringe, such as the one on this page. They are 4.5” (11.4cm) long with two sampling holes at the tip. |
