Material: flexible and durable plastic, reusable cycle after cycle. Does not tangle, unlike string mesh. Horizontal or vertical use: professional support for guiding and supporting plants. 3-inch diameter roll core. How to Use Install it horizontally over the crop to spread the branches, or vertically attached to stakes or the tent structure. Stretch the netting and secure it at all four corners before the plants grow: installing it late forces the foliage. Place it at the height where you want the canopy to open and add a second level if the plants continue to stretch. Guide each branch through a different square, without pressing it against the plastic. At the end of the cycle, remove the plant material, wash the netting with water and mild soap, and let it dry completely. Roll it onto its core and store it dry, without weight on top, so it does not deform.
