DL Wholesale Light-Proof Black Duct - 10-in x 25-ft

Flexible Light-Blocking Ventilation for Intake and Exhaust - 25 ft Run

Light leaking through ducting can interrupt a plant's dark period, and a duct that collapses or tears restricts airflow. This black flexible duct uses a blackout coating to block light and a spring steel wire helix to hold its shape and resist punctures. When installed properly, it carries air between your fan, filter and room without letting light in.

At 10 in in diameter and 25 ft fully extended, this single unit suits a regular indoor grower connecting a tent or grow room to a fan and filter. Growers with longer or multiple runs can order additional units.

Key Features & Benefits

• Blackout coating — blocks light from entering through the duct wall.

Frequently Asked Questions

Q: Will this duct let light into my grow space?
A: The blackout coating is designed to block light. When the duct is properly installed, no light should pass through the duct wall to disturb your lights-out schedule.

Q: What does the wire helix do?
A: The helix is a coiled wire built into the duct wall. It keeps the duct open, adds flexibility for routing and helps resist punctures and tearing.

Q: Is this duct insulated?
A: No, it is non-insulated ducting. If you need to reduce noise or heat transfer, consider a separate insulated duct.

Q: How long is it?
A: It measures 25 ft when fully extended. Stretch it straight to cut down on airflow resistance, and avoid sharp bends.

Q: What temperatures can it handle?
A: It is rated for 0°F to 185°F (-18°C to 85°C), which covers typical intake and exhaust use.

Q: Can I use it for both intake and exhaust?
A: Yes. It suits both intake and exhaust runs in tents, grow rooms and greenhouses.
