Terra-Duct Ducting - 4 in x 25 ft

Durable Airflow Routing for Grow Spaces - 25 ft Run

Poorly routed or flimsy ducting wears out, sags and restricts airflow to fans, filters and lights. Terra-Duct uses a three-layer wall with polyester reinforcement to hold its shape in regular use, and its black interior is made to resist visible dirt buildup. Two large black plastic zip ties come with each 25-foot section, so you can fasten it right away.

This 4 in x 25 ft length suits a regular indoor grower connecting fans, filters and exhaust points in a single run. Commercial rooms can order multiple units to cover longer or multiple runs.
