What is a grow room Fan Controller and how does it Work?
A grow a room fan controller is a tool that you use to control the fans in your grow room. It works by regulating the speed of ventilation fans so you can set your desired temperature and humidity range, which will then be achieved with a steady airflow. The benefits are increased efficiency, more precise climate control, as well as energy savings!
Why do I need one?
- You should consider getting yourself a grow room fan controller if:
- You want better accuracy for controlling temperatures or humidities
- You would like to save on electric costs over time (energy efficient)
- Your growing area has multiple vents and/or exhausts. If this is true for you, then you should definitely get a grow room fan controller because it will be able to monitor and regulate each of them independently!
What is the best Type Fan Controller for grow room?
There are many fan controller options when it comes to growing room equipment. These range from simple knob-style controllers that allow control over speed and direction (and sometimes more such as timers), all the way up to programmable, digital units with touch screen interfaces allowing you to set a specific temperature and humidity conditions for your plants throughout their lifecycle.
There is no one correct choice; each has its pros and cons depending on your needs in terms of cost, features, ease of use, and location within the grow space itself.
We’ll run through a few different examples below:
The most common type of accessory found at dispensaries is what’s called an inline duct booster fan. This allows growers to regulate the airflow by fitting between two pieces of ducting (or between a duct and an inline fan).
Simply place the booster fan at either end, adjust your fans to 100% speed, and dial in how much you’d like boosted airflow.
The more boosters added, the higher the amount of airflow will be increased; however obviously increasing too far beyond “100%” can cause problems such as over-cooling and overheating plants.
The next type is called a variable speed controller, which is very common for grow tents or small grow rooms that use PC Fans. This simply allows growers to control both the direction and speed of their exhaust fans with one easy box – so it’s usually placed near the bottom outside edge on each tent closest to where you exhaust.
This is a very simple and cost-effective method for growers who want to dial in the exact airflow while keeping it all within reach of their hand; however, some varieties can be confusing or difficult to work with, especially when you add more than two fans (plus they’re not great if your tent uses multiple intake ports).
The last type we’ll mention here is “smart” fan controllers. These allow complete control over how many fans run at any given time; plus most have LCD screens which make tuning into specific temperature/humidity ranges easy and effortless!
Some even come with built-in timers that will switch off the controller after a set period of time so there’s no worry about leaving them on 24/365. There are many varieties of smart controllers on the market, most with their own unique features and benefits; however, typically they’re more expensive than simple variable speed controllers or inline duct boosters.
How do I Choose the right Type for my needs?
There are a few different types of grow room fan controllers available, each one with its own benefits and downsides. We will discuss them briefly below:
PWM Controllers :
A PWM controller monitors the temperature of your air going into the grow room to determine if it needs to speed up or slow down ventilation fans in order for you to achieve optimal climate conditions.
They do this by using a sensor that measures both ambient airflow as well as internal temperatures (inside your growing area).
The downfall is that they only work with DC axial flow type fans, so when purchasing these make sure you get an appropriately sized model! If not, then there could be some issues such as underpowered performance or potential overheating problems due to too much electricity being pushed through.
RPM Controllers :
With RPM controllers, you set your desired temperature, fan speed (RPM), and then the controller will work to maintain that range for you by turning ventilation fans on or off as needed!
They are easier to use than PWM models but they don’t offer the same level of accuracy when it comes to temperature control.
Wi-Fi Controller:
A Wi-Fi grows room fan controller is one that can be controlled via a smartphone application. This allows growers more convenience in being able to adjust things while out of the growing space without needing physical access – all with just a few clicks!
The upside here is definitely how convenient this type of model is compared to other options, however, there are some downsides such as how they can be more expensive. If you think this type of model would work best for your grow room then definitely go with one, but if not then it might not be worth the extra money!
Pros and Cons:
These are some benefits that come along with using a grow room fan controller in order to control climate conditions inside your growing area:
Increased efficiency (better airflow) More precise humidity and temperature control Energy savings due to turning fans on/off when needed Increased lifespan of ventilation equipment since there is no overheating possible by having them run constantly.
The downsides? It’s hard to find any besides possible price depending on which model you choose – so don’t let cost keep you from getting yourself a great tool for your grow room!
FAQs about using a grow room Fan controller
Can I use a digital or analog grow room fan controller?
A: The choice is really up to you! But keep in mind that not all models work with certain fans so double check before buying if you can only find one type available for sale where you are looking.
Also bear in mind things such as ease of reading dials vs screen when making your decision since this will be important depending on personal preference. Lastly, take into account any specific features that may determine which one would suit your needs better (such as alarms, etc).
How many speeds should my ventilation system support?
It depends on the size of your room. If you have a small grow tent, then one speed should be enough for general ventilation.
However, larger rooms require higher speeds so that there is always airflow since plants can suffer if not properly vented with fresh air! Also, keep in mind how many fans are being used to ventilate your growing area – more than one requires multiple vents/exhausts which will need corresponding fan controllers increasing the total amount of speeds supported by all combined together.
How do I mount my controller?
The best way would depend on what type it is and where exactly you’re placing it (some models include mounting brackets while others don’t).
For analog ones without any accessories included, you would use a screw or nail to keep it in place.
For digital ones, there are brackets included with many models but if not, double-check the description and make sure it’s compatible with your chosen mounting option before buying!
Does my fan controller need to be grounded?
This depends on where exactly you’re installing it at as well as what type of system is being used for ventilation (AC vs DC). If using AC power sources then grounding will depend on local electrical code requirements since this can vary from country to country so please do some research beforehand if unsure.
Also bear in mind that certain fan controllers may have built-in surge protection which means they don’t need any additional ground wire – always best to take a look at the description of a particular model to see if this applies or not.
What type do I need?
There are basically two types – analog dial or digital full function models but before making any final decisions please double-check what features will best suit your needs by looking at descriptions carefully first!
For example, many factors including size/capacity requirements may depend on how many fans you’re using so double-check how much power is needed to support the type of ventilation equipment being used in your grow room.

How does a fan speed controller work?
A fan speed controller (also called a variable-speed fan controller, switchable-voltage fan control, variable voltage fan control or adjustable voltage fan switch) is used to adjust the output of electric fans.
I don’t have the previous version to compare it to, but this thing is amazing! I’ve connected it with their 6″ CloudLine fan in a 3×4 tent and with it, along with an Inkbird humidity controller, I can maintain an absolutely perfect VPD. This makes these photoperiod Shockwave F2s grow
