DL Wholesale Light-Proof Black Duct - 6 in x 25 ft

Keep Dark Cycles Dark With Flexible Ducting - 25 ft Extended Length

Ventilation ducting can leak light into a room and disrupt the dark period your plants depend on. This duct has a blackout coating and an aluminum construction, so a properly installed run carries air between your fan, filter and space without adding a light path. A built-in corrosion-resistant wire helix keeps the tube reinforced and flexible.

At 6 in in diameter and 25 ft fully extended, this single length suits a regular indoor grower connecting a tent or grow room to an exhaust fan or carbon filter. You can cut or stretch it to fit your layout, and it works for both intake and exhaust runs.

Key Features & Benefits

• Blackout coating — blocks light along the run when installed properly.
• Aluminum construction — flame resistant material for ventilation use.
• Wire helix reinforcement — built-in and corrosion resistant, so the duct holds its shape and bends easily.
• Temperature range of 0°F to 185°F (-18°C to 85°C) — covers typical room and exhaust air conditions.
• Non-insulated design — lets heat dissipate along the run.

Who Should Use DL Wholesale Light-Proof Black Duct

Home and commercial growers who run grow tents, grow rooms or greenhouses and need light-tight air movement. It also suits other ventilation jobs such as kitchens and bathrooms.

Frequently Asked Questions

Q: Is this duct really light proof?
A: It has a blackout coating that is specified as light proof. Light stays out when the duct is installed properly, with tight clamped connections at each end.

Q: What temperatures can it handle?
A: It is rated for 0°F to 185°F (-18°C to 85°C). That covers normal intake and exhaust air for most indoor cultivation setups.

Q: Is it insulated?
A: No, it is non-insulated. Heat dissipates along the run, which can help reduce temperature swings in the room, though you may want insulated duct for very hot or cold surroundings.

Q: Can I use it for both intake and exhaust?
A: Yes. The flexible build suits both intake and exhaust piping between fans, filters and your grow space.

Q: What does fully extended mean?
A: Flexible duct arrives compressed. Fully extended means stretched to its full 25 ft length, so allow room to pull it out and keep bends gentle for better airflow.
