Your favorite nutrient measuring tool now comes in a kit containing 2 different sized needle tips. Use the 8 inch tip for cracking into your newer bottles, then bust out the 14 incher when you're getting to the bottom of those old ones. The Nute Needle is a two component measuring syringe designed for measuring liquid nutrients and liquid fertilizers. The needle measures 1/4 inch in diameter and is coated with a polished nickel plating, which ensures that your product will stand the test of time and live up to rough handling. The syringe's body is made of high durability polycarbonate which ensures maximum visibility when measuring liquids. The measurement markings are raised, so they won't scratch or wear off like traditional "single use" syringes.
