Here's a quick recap on the reasons for using an extraction system...
The Importance of Ventilation
Regularly extracting and replacing air in your grow room has a significant and positive impact upon your plants. They need this constant supply of fresh air to replenish CO2 and oxygen levels and maintain healthy temperatures. A good ventilation system also helps to minimise the risk of damp and mould and let’s you more closely manage grow room humidity.
All you need to set up an extraction/filtration system is the following:
- A matching Carbon Filter
Alternatively, you could just opt for a Complete Extraction/Filtration Kit that includes each and every required component.
Although you may have the fan(s) for the job, manually finding the optimum fan speed is very difficult - especially during summer when temperatures tend to change a lot between day and night. Your fan(s) alone won’t respond to such fluctuations, reducing their overall effectiveness and in the worse case scenarios restricting plant growth.
Fortunately a solution does exist...
Fantastic Fan Speed Controllers
Fan speed controllers allow you to adjust the level of extraction and/or intake in accordance to grow room conditions. There are currently a number of excellent models available to choose from, accounting for a variety of factors and the demands of different growers – just make sure you don’t go without one!
So, what do we consider to be the "BIG 3" fan speed controllers? Let's find out!
