Terra-Duct Ducting - 6 in x 25 ft - Three-Layer - Black Interior

Durable Airflow Ducting for Grow Rooms - 25 ft Length

Ventilation runs take a beating in warm, humid cultivation spaces, and weak ducting can tear or sag. Terra-Duct uses a three-layer construction with polyester reinforcement to hold its shape and carry air from fans to filters and exhaust points. The black interior and the included zip ties make it a practical choice for a clean, secure installation.

This is a single 6 in diameter section that runs 25 ft. It suits growers who need one continuous run, such as connecting an inline fan to a tent or room exhaust, without joining shorter pieces. Buy several lengths for larger commercial layouts.
