EZ-Clone® Colored Cloning Collars are designed specifically to be used in the EZ-Clone® Cloning Systems. They are manufactured from a sterile material and are engineered to protect and hold your cuttings upright in the lid, exposing the top leaves to air and light, while allowing the stems of your cuttings to be completely unrestricted to the inside of the misting chamber. Currently, EZ-Clone® Colored Cloning Collars are available in four vivid colors, green, purple, white, and grey. All four colors come in packs of 35.
