AC Infinity Terraform 9 – All-in-One Grow Tent Air Conditioner, Heater & Climate Control (UK)
AC Infinity Terraform 9 – One Box, One Duct, Every Season
The usual way to control a grow tent's climate is to buy a fan for summer, a heater for winter, a dehumidifier for autumn and a controller to stop them fighting. Four boxes, four plugs and a lot of hoping. It works, in the way a committee works.
The Terraform 9 is the UK version of AC Infinity's all-in-one tent climate unit (the Terraform 8 in the US). It cools, heats, circulates and exchanges air through a single duct, switching between modes automatically to hold the temperature or VPD you set. For dedicated dehumidifying, you switch to a two-duct setup.
Why it's worth it
- Set and forget: choose a target temperature or VPD and let the adaptive AI pick cool, heat or fan as conditions change, when paired with a Controller AI+ or newer.
- Single-duct simplicity: one duct into the tent for cooling, heating or air exchange.
- Self-evaporative design: condensate is pumped to the condenser and evaporated, so there's far less emptying.
- Built for tents up to 10×10ft (about 3 × 3m), on wheels so it moves easily.
- App connectivity through AC Infinity's AI controllers: automations, data, alerts and grow guides.
Note that the self-adjusting climate modes need a Controller AI+ or newer; they're not available with the Controller 69 Pro+ or earlier.
Not just for growers
A climate-controlled tent is equally useful for tropical plant collections through a British winter, orchid and carnivorous plant setups that hate summer heat, and anyone overwintering tender plants who is tired of buying a different gadget each season.
🌿 Rose's Pro-Tip: set a VPD target rather than separate temperature and humidity numbers. VPD is what the plant actually feels, and letting the Terraform chase one number stops it switching modes back and forth.
