Super Trellis can be used outdoors in some cases. Generally it is recommended to use Super Trellis in areas that are mostly shaded. Darker colors are susceptible to warping in hot environments with direct sunlight. The darker pigments in the colors absorb more light and reach temperatures much greater than the ambient temperature of the air. When using a Super Trellis in an outdoor setting, we recommend building your trellis with our Corner kit in the “totem” arrangement. By creating a four sided structure, the chances of warping are greatly reduced.  If you are concerned that your environment may be too warm for Super Trellis, consider purchasing light colored products (white, grey, blush, lemon, etc). These items can sustain higher ambient temperatures up to 90 degrees Fahrenheit and direct sun for extended periods of time. At least partial shade is always recommended.
