Use zipper strips to create very neat light proof openings in DIY grow rooms made from plastic sheeting. These sticky zippers are securely stitched onto self-adhesive anti-rip strips for easy use and long lasting durability. Each zipper strip is 2 meters in length.
The self-adhesive zipper strip is very easy to install. Simply stick the zipper strip to your plastic sheeting unzip and with a sharp blade or scissors cut your opening.
