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; paired with a UIS controller the T7 corrects 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: cycles via UIS controller 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.
- Connect it to a compatible UIS controller port.
- Set your target temperature or VPD in the app; the controller cycles the heater to hold it.
