Pairs well with
The AC Infinity Cloudforge T3 V2 is a 4.5-litre compact ultrasonic humidifier designed for grow tents, propagation spaces, and smaller indoor growing areas where dialling in humidity makes a real difference to plant health and transpiration. It integrates with the AC Infinity UIS ecosystem for automated RH control, runs quietly, and delivers cool mist at an adjustable output rate. The T3 is the smaller sibling to the T7 — purpose-built for tents and tighter spaces where a full-size unit would be overkill.
Specifications
- Use distilled or filtered water — tap water with high mineral content leaves white residue on leaves and internal components over time.
- For propagation and seedlings, run the T3 on a lower output setting to maintain high RH without creating excessive condensation in the dome or tray area.
- Clean the tank and ultrasonic disc every week during active grows — mineral scaling builds up faster than most growers expect.
How to Use

Automate the T3 with an AC Infinity UIS controller — it runs when RH drops below target and stops when it's reached.
PropagationSeedling trays, domes, and propagation tools — high humidity during early stages dramatically improves clone and seedling success.

Frequently Asked Questions
What is the difference between the T3 and T7?
The T7 has a 15-litre tank versus the T3's 4.5-litre capacity, and delivers a higher maximum output rate — making it suited to larger grow rooms. The T3 is the compact option for grow tents and smaller spaces, with the same UIS integration and ultrasonic cool mist technology.
Does the T3 require an AC Infinity controller to work?
No. The T3 operates standalone with manual output adjustment. Connecting to a UIS controller adds automated RH-based triggering — significantly more useful in a grow tent where manual checking is inconvenient.
Is it suitable for a propagation dome or clone tent?
Yes. The T3 at a low output setting works well for maintaining elevated humidity in propagation environments. Position it outside the dome with the mist directed toward the vent rather than inside if condensation becomes excessive.
What RH range is ideal during vegetative growth?
Most crops prefer 50–70% RH during vegetative growth, dropping to 40–50% during flowering to reduce mould and mildew risk as canopy density increases. The T3 paired with a controller makes maintaining these targets across both stages straightforward.
How often does the tank need cleaning?
Clean the tank and ultrasonic disc every 7–10 days during active use. Rinse with white vinegar diluted in water, scrub the disc gently, and rinse thoroughly before refilling. More frequent cleaning is needed with harder tap water.
