EZ-CLONE® Classic Cloning Collars are designed specifically to be used in the EZ-CLONE® Cloning System. 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. These EZ-CLONE Classic Cloning Collars are available in a new high-density Hard material as well as the same great Soft material that we have been using for years. Be sure to ask for them today at your favorite retailer. Also available in the following sizes: 17, 35, 65 and 280 bulk packs
