Description
Duct ThermoForge Heat Exactly Where Your Plants Need It
The AC Infinity Thermal-Resistant Hose is the purpose-made heat duct for the ThermoForge T7 and S7 grow heaters, which come without ducting. It threads onto the heater's 4 inch (10.2 cm) heat outlet and carries warm air into a grow tent, propagation space or the coldest corner of a grow room, so the heater can sit outside the tent while it lifts temperature and steadies VPD around the plants. Made from heat-resistant polypropylene, it stays cooler on the outside than layered foil ducting while moving hot air, and it extends from 0.7 m to 2.4 m (2.3 to 8 ft), holding whatever bend you give it so the heat goes where you aim it.
Key Benefits
- Made for the ThermoForge T7 and S7, with a counter-clockwise thread that seals onto the heat outlet
- Heat-resistant polypropylene with a cooler outer surface than layered ducting
- Extends to 2.4 m (8 ft), four times its packed length
- Flexible but form-holding, to direct warm air under or across the canopy
- Leak-free threaded joint that keeps heat going into the grow space
How to Use
- Heat outlet only: line the thread up inside the ThermoForge's exhaust port and turn the hose counter-clockwise until it seats firmly.
- Intake port: the hose does not fit it; use standard flexible layered 4 inch ducting there for fresh-air intake or a closed loop.
- Route the warm air into the tent through a duct port, keeping bends gentle.
- Aim it below or across the canopy so the heat spreads rather than hitting one plant.

Frequently Asked Questions
Does the ThermoForge T7 come with a hose?
No. AC Infinity supply the T7 without ducting, so you need this hose, or standard 4 inch ducting, to carry its heat into a tent.
Can I fit it to the intake port?
No. It is made for the heat outlet only. The intake ports work with flexible layered 4 inch ducting.
Why not use ordinary foil ducting on the heat outlet?
This hose is heat-resistant polypropylene that stays cooler on the outside while it carries hot air, and it threads straight onto the port for a leak-free seal.
How far will it reach?
It stretches from 0.7 m packed to 2.4 m (8 ft) fully extended, and holds the shape you bend it to.
