Description
Hold a Steady Grow Temperature Through Cold Nights
The AC Infinity ThermoForge T7 Smart Heater is a 1000W PTC ceramic heater that raises and holds grow room or grow tent temperature automatically. Overnight dips and lights-off drops slow metabolism and knock plants out of their ideal range; its built-in controller and sensor probe correct that around the clock without you watching a thermometer.
Key Benefits
- 1000W PTC ceramic element: efficient, even, flame-free heat across 10 precise levels
- VPD and temperature control: programme by target temp or VPD, not just on/off
- Dual-duct design: run closed-loop for heat efficiency or open-loop to draw fresh air
- Adaptive AI: learns the space to pre-empt drops rather than only reacting
- Automatic operation: the built-in controller cycles it to hold conditions day and night
- Protects plant health and growth rate through cold snaps and unheated spaces
Fixing cold snaps and lights-off temperature drops
Draughty rooms and lights-off periods can drag temperature below the ideal band, stalling growth and pushing VPD out of range. Rather than checking a thermometer and flicking a heater on and off yourself, the ThermoForge T7 responds to your target automatically, so temperature stays steady through every dark period and cold night.
How to Use
- Place the heater in the tent or room with clear space around it for airflow.
- Choose closed-loop ducting for maximum heat retention, or open-loop to bring in fresh air.
- Run it on its own built-in controller, or connect it to an AC Infinity UIS controller port if you already use one.
- Set your target temperature or VPD; the controller cycles the heater to hold it.

Questions & answers
How powerful is it?
1000W, from individual PTC ceramic plates with PWM control across 10 heat levels.
How is it controlled?
By its built-in controller and sensor probe, which hold a target temperature or VPD and cycle the heater for you. It also works with an AC Infinity UIS controller; a WiFi-capable one adds app tracking and alerts.
What are the two duct ports for?
Run them closed-loop to keep heat in, or open-loop to draw in fresh air. The ports are 10.2cm (4in).
How does it compare with the Lighthouse 2KW Grow Room Heater?
The T7 is a smart 1000W heater with 10 levels and temperature or VPD control. The Lighthouse is a fan heater giving up to 2000W, with a built-in thermostat and a fan-only setting.
What safety features does it have?
AC Infinity list a tip-over alarm, flame-retardant materials and overheat protection with auto-restart.
