Shorten day length with photoperiod fabrics.

PAK offers a variety of light exclusion fabrics that add to your investment in a blackout system and ensure extended seasons of reliable light exclusion. These fabrics are made of rugged polypropylene with reinforced seams for added durability.

Plants grown under photoperiod cloth are more disease free because less humidity develops under the fabric. The fabric also serves to conserve heat in the greenhouse during the winter months. Works with automatic, semiautomatic or manual systems.
