FloraFlex FloraClip Insert: Formerly known as the Barbed Insert, the FloraClip Insert performs a swift conversion of your Round Flood and Drip Shield from a top-feeding system to an Automated Hand Feed + Top-Feeding Drip System. Easily insert a FloraClip into any of the 18 louver air vents on the drip shield and clasp it onto your 1/4" OD FloraFlex Tubing.
