Frequently Asked Questions
What is in the AC Infinity Cold Weather Climate Control Bundle?
One Thermoforge T7 1000W heater (AC-SFT7), one 2.5m thermal-resistant hose for the T7, one Hydrone 5 dehumidifier (AC-DHT5) and one Cloudforge T5 9L humidifier (AC-CFT5).
What size tent does the Cold Weather Climate Control Bundle suit?
The Hydrone 5 is built for tents up to 5x5ft (around six plants), so this bundle suits tents up to that size. For bigger spaces, the Hydrone 7 covers up to 10x10ft and is sold separately.
Is ducting for the Hydrone 5 included?
No. The Hydrone 5 uses dual 6 inch duct ports and standard ducting, which is not part of the bundle. The included hose is only for the exhaust port of the Thermoforge T7.
Do I need a UIS controller?
Not to run them, but it is worth having one. The Hydrone 5 has no humidity sensor of its own. It runs at the drying level you set (1 to 10) until you turn it off, so it needs a UIS controller with a sensor, or an outlet controller, to switch on and off at your target humidity. The T5 humidifier has its own onboard humidity and VPD triggers. A UIS controller is sold separately and also brings all three devices into the AC Infinity app.
Why have both a dehumidifier and a humidifier?
Cold rooms can swing between damp air and dry air. The Hydrone 5 pulls humidity down to as low as 25% RH, while the Cloudforge T5 adds it back with warm or cool mist, so you can hold your target range either way.
What does the Thermoforge T7 do?
The T7 is a 1000W smart heater with 10 heat levels, AI climate control and temperature and VPD automation. Its dual duct ports let you run it open loop with fresh air intake or closed loop to recirculate warm air.
Beschreibung
The AC Infinity Cold Weather Climate Control Bundle is a complete winter grow room set: a Thermoforge T7 1000W heater with its 2.5m thermal-resistant hose, a Hydrone 5 dehumidifier and a Cloudforge T5 9L humidifier. Heat the room, pull excess moisture out and put it back when the air gets too dry, all from one UIS compatible set that costs less than buying the four items separately.
What's In The Bundle
- 1 x Thermoforge T7 (AC-SFT7): a 1000W smart heater with adaptive AI control, 10 heat levels and dual duct ports for open or closed loop setups.
- 1 x Thermal-Resistant Hose (2.5m): a 4" heat-resistant hose that stretches from 0.7m to 2.5m and locks onto the T7 exhaust port.
- 1 x Hydrone 5 (AC-DHT5): a plant dehumidifier for tents up to 5x5ft with 10 drying levels, humidity down to 25% RH and dual 6" duct ports.
- 1 x Cloudforge T5 (AC-CFT5): a 9L humidifier with warm and cool mist, UV-C sterilisation, up to 800ml/h output and VPD and humidity triggers.
Why Choose This Bundle?
- Control humidity in both directions: cold rooms swing between damp and dry. The Hydrone 5 brings humidity down and the T5 brings it back up, so you can hold your target range either way.
- Steady, adjustable heat: the T7 runs across 10 heat levels instead of switching hard on and off, which keeps night temperatures from dropping away.
- Warm mist for cold rooms: the T5's warm mist is up to 3x more efficient in cold conditions, so it holds humidity with less water.
- Hose included: the T7 needs its own thermal-resistant hose on the exhaust port, and it is already in the set.
- Ready for app control: all three devices sit on the AC Infinity UIS platform, so a UIS controller can bring them into one app with timers and automation.

Who Is This For?
Growers with a tent up to 5x5ft in a cold room, shed or garage who want their winter climate sorted in one go. It suits flowering through the colder months, when damp air and cold nights are the biggest threat to a crop. The Hydrone 5 has no humidity sensor of its own, so a UIS controller or outlet controller is recommended to switch it at your target humidity, and it is sold separately. Ducting for the Hydrone 5 is not included, as it uses standard 6" ducting rather than the T7 hose.
What To Pair It With
- Control: link the set together with an AC Infinity UIS Controller.
- Airflow: add a clip fan and extra humidity capacity with the Fan Favorite Duo A, Duo B or Duo C.
