Ventilation control – climate controllers & speed controllers for grow boxes

A reliable ventilation control system helps you to precisely regulate the temperature, humidity and air exchange in your grow box. With a suitable climate controller, speed controller or step-down transformer, you can adjust the output of your exhaust fans to suit the requirements of your indoor grow.

Whether it’s simple manual fan control or intelligent climate control with sensors and automatic functions – at Growland you’ll find a range of solutions for small grow boxes and larger grow rooms.

Climate controllers – automatically regulate temperature and humidity

A climate controller for grow boxes enables the demand-based control of compatible fans. Depending on the model, built-in or external sensors measure the temperature and humidity and automatically adjust the fan output according to your settings.

Modern climate controllers offer a range of functions:

• Automatic fan control based on temperature and humidity
• Adjustable minimum and maximum speeds
• Control of compatible supply and exhaust fans
• Digital display and monitoring of key climate parameters
• Depending on the model: timers, VPD control or app connectivity

This allows you to adapt the ventilation in your grow area to changing conditions without having to constantly adjust the fan output manually.

Speed controllers and step transformers for fans

Not every grow box requires a comprehensive digital climate control system. For many applications, a simple speed controller for tubular fans is sufficient.

Stepless speed controllers

With a stepless speed controller, you can manually adjust the output of suitable AC fans. This allows the airflow to be adapted to actual requirements.

It is important that the controller is suitable for the type of fan used and that the permissible electrical load is observed.

Step transformers

Step transformers enable the speed control of compatible AC fans across several fixed voltage steps.

One advantage of this technology is the often quiet motor control without the typical electrical hum that can occur with certain electronic speed controllers.

At Growland, you’ll find various models from Sentera Controls to suit different performance requirements.

EC fan control – efficient regulation of modern duct fans

Modern EC duct fans often offer particularly flexible and energy-efficient speed control.

Special EC controllers are used for these fans, which communicate with the fan via compatible control signals or connections.

In our range, you’ll find suitable control solutions from Prima Klima and GrowControl, amongst others.

Depending on the model, these controllers allow for manual speed control or automatic adjustment of fan output based on measured environmental parameters.

Smart grow box control with AC Infinity and GrowControl

If you want to monitor and automate your indoor climate more comprehensively, Growland offers modern control systems with advanced features.

AC Infinity controllers allow for the centralised control of compatible UIS devices, depending on the model. Various processes can be automated via digital settings, sensors and, for supported models, via an app.

GrowControl climate controllers also offer versatile options for controlling compatible EC and AC fans.

Depending on the system, additional sensors can be integrated to monitor, for example, temperature, humidity or negative pressure.

Matching control accessories, connection cables and sensors complete our range.

Which ventilation control system is right for your grow box?

The right fan control system depends primarily on your existing exhaust air system and the functions you require.

Stepless speed controller – Simple manual control of compatible AC fans

Step transformer – Multi-stage, often low-hum speed control of suitable AC fans

EC fan controller – Control of compatible EC fans

Digital climate controller – Automatic ventilation based on temperature and humidity

Smart Grow Controller – Advanced automation of multiple compatible devices

When making your choice, pay particular attention to compatibility with your fan, the required connections and the supported control functions. Not every controller is suitable for every AC or EC fan.
