Climate Controllers

A grow room climate controller replaces the individual thermostats, humidity controllers, and CO2 monitors you would otherwise need to manage separately. The better units read temperature, relative humidity, and CO₂ concentration through a single multi-sensor, then activate or deactivate connected equipment, fans, heaters, dehumidifiers, and CO₂ generators to hold each parameter within the range the plants need at each stage of growth.

BioFloral carries climate controllers from Grozone and Trolmaster, two of the most established names in controlled environment automation. The range spans from the Grozone HT dual-output temperature and humidity controller through to the Trolmaster Hydro-X Pro, a multi-zone system with a 4-in-1 sensor built for large-scale or commercial operations. All products are in stock and ship across Canada.

Best Grow Room Climate Controller for Every Setup

Best for Compact Tents and Small Grow Rooms

The Trolmaster Tent-X (TCS-1) is purpose-built for grow tent environments, with a 3-in-1 sensor and a compact controller managing temperature, humidity, and supplemental devices without the overhead of a full Hydro-X system.

Best for Mid-Size Rooms with Independent CO2 Control

The Grozone HTC and SCC1 both manage temperature, relative humidity, and CO₂ from a single controller, with relay output boxes available to expand the number of connected devices without adding a second unit.

Best for Large-Scale and Commercial Grows

The Trolmaster Hydro-X Pro (HCS-2) with its 4-in-1 sensor manages multiple zones and integrates with the full range of Trolmaster device stations, covering temperature, humidity, lighting, CO₂, and irrigation across a facility from a single system.

Best for Budget-Conscious Growers Who Need Dual Control

The Grozone HT delivers reliable day/night temperature and humidity control with a clear display at a lower price point than fully integrated CO₂ systems, suitable for growers who manage CO₂ separately or not at all.
