Control Freak – Frequency Fan Controller 7A
- Produces a far smoother output waveform in comparison to standard PWM fan speed controllers
- One of the few controllers to be recommended for use with Isomax fans by their manufacturers, Can
- Complete control from 10-100% fan speed
- Reducing your fan speed with the Control Freak saves electricity, unlike many other fan speed controllers
- Remote temperature probe allows it to control the fan speed for you (in Automatic mode)
- Large LCD display
- Adjustable minimum and maximum fan speed
- Lightweight (unlike hybrids!)
- Plug and play design
The Control Freak Frequency Fan Controller 7A equates to a massive step forward in technology which controls your environment. Previously fan speeds were controlled by current resistance to the fan or manipulating the voltage delivered to the fan, both of these have significant drawbacks, the prime one being additional noise from the fan and a limited number of fan speed options respectively.
The Frequency Controller works by affecting the supply to the fan by restricting the frequency of the supply, this results in the flexibility of a resistance based controller (speed control at 1% increments between 10% and 100%) but without the type of ‘hum’ to which we have become accustomed to with these types of controllers. Controlling the fan in this way includes greater energy efficiency and less stress to the parts of the fan meaning it will not need replacing as often.
This controller has two plug sockets to control an intake fan and an outtake fan, you can set your own speed, though these parameters are pre-set to a minimum 10%, maximum 100%. The unit also features adjustable bandwidth, this basically sets the number of degrees the unit will let the temperature drift up before moving back to full power, while the temperature is within the prescribed bandwidth the unit will increase the fan speed in smaller increments, allowing time for the adjustment to take effect before speeding the fan up again. It will continue to do this until either the desired temperature is reached of the bandwidth is reached (at which point the fans will speed up to the pre-set maximum. Therefore to minimise the large rapid fluctuations in fan speed that are not usually desirable we suggest setting the bandwidth somewhere near the maximum (9 degrees).
The thermostatic control can be overridden by switching the unit to manual mode, this allows the user to set the fan speed at 1% increments between 1% and 100% and it will maintain that fan speed regardless of the temperature of the room.
** Please note this unit is only compatible with AC fans.

Why your grow room needs fans
Your grow room needs fans all year round, no matter what the temperatures are like outside – they are always beneficial. They help with a variety of different problems that might otherwise arise and don’t just work to cool a room down. Ways they can help include:
- To Circulate the Air In Your Grow Room
- To Remove Excess Heat & Hot Spots
- To Control Humidity
- To Prevent Pests and Diseases
- To Control CO2
- To Circulate the Air In Your Grow Room
Outside, plants are going to encounter wind at some point. However, the wind never blows in the same direction for very long, and so you want to avoid having a static fan blowing. Oscillating fans and others that have movement are ideal for creating a more natural air circulation. You can place two fans in opposite corners to create a circulating vacuum of air.
To Remove Excess Heat & Hot Spots
Your grow room can easily get too warm depending on the conditions outside and within the area, you are growing. Grow lights emit heat, and whilst it may not feel like much to you, a slight increase in temperature can really affect your plants.
Some grow lights emit more heat than others but even with lights known to run cooler such as air-cooled lighting and LEDs, it is still wise to have fans blowing. They will help to keep the general temperatures lower and help with air exchange.
To Control Humidity
Another factor that can create problems in a grow room is humidity. Plants release water vapour throughout the day and this increases the humidity. If this level isn’t controlled, the growing conditions will decline.
A good ventilation system will help to wick away some of the water released during transpiration. This allows your plants to absorb more water and pull up nutrients through their root systems, which in effect helps with boosting growth.
To Prevent Pests and Diseases
Good air circulation will help to prevent pests and diseases taking hold. Stagnant and humid conditions are the preferred breeding ground of mould, powdery mildew, spider mites and fungus gnats. And we don’t want any of those to get in!
A steady breeze thanks to a few fans also makes it harder for the pests to establish themselves on the plants.
To Control CO2
Plants need outside air for one very basic reason: CO2. This is absorbed naturally throughout the day as part of a plant’s nutrient cycle. With a sealed grow tent set-up, the level of CO2 will gradually decrease, and this will limit growth.
Ventilation brings in the fresh air and fresh CO2 from outside whilst removing the old air from your grow room.

About Control Freak
Control Freak is a product by Highlight Horticulture.
Highlight Horticulture started trading from a small high street shop in Mansfield
Nottinghamshire in 1994. It was the idea of two good friends trying to spread the
word about different, progressive and modern growing techniques to the public. It
was one of the very first hydroponic retailers in the UK. We started to supply at a
wholesale level to the ever-growing number of UK stores in 2005. Since that time we
have developed into one of the largest homegrown companies in the British supply
chain. We still have a small retail outlet and that helps to keep us grounded in, and
connected too, the wants and needs of you, the stores that continue to make the UK
the dynamic, vibrant and thriving scene that it is today.
We were recently awarded the title of the UK’s favourite Wholesaler by Garden
Culture Magazine as voted by you guys, the UK shops. We are very proud of this
achievement and thankful to those of you who voted for us. We will try our hardest
to continue to provide you with great products at great prices, with fast, friendly and
