Got an extraction system? This is the first thing you should fit in your grow room. Here's how you do it right.
This is part 3 of a 3 part series into ventilation:

In this article, we'll show you how to fit a ventilation system.
Here, we show you how to do it in a four light system.
To get started, you will need:
- Extractor Fan
- Carbon Filter
- Intake Fan (if needed)
Wire your fans up (instructions are included) if you need to. Some will be ready to go straight out the box.
Plug them in to check they work, and identify the exhaust side (air out).
Attach your carbon filter to the intake side of your fan. Secure it with a Fast Clamp.
Next, attach ducting to the exhaust end of your filter. Secure with a Quick Release Duct Clip.
Once you’re happy with the hanging height of the extraction system, feed the power lead through one of the lower ports, and the ducting through one of the higher ports. Pull the drawstring tight around both ports to keep light in and bugs out.
Now the intake fan can be installed. There's no carbon filter this time round - secure the ducting to both sides of the unit using Quick Release Duct Clips.
Once assembled, you can place your fan on the outside of your tent and feed the ducting through one of your lower ports. Make sure your fan's facing the right way to draw air in (exhaust in).
Lastly, attach a Horti-shield Bug Blocker to the end of your intake ducting (the length that's outside your tent).
We also recommend using air circulation fans to stop hot pockets of air from forming. Make sure you don't point them directly at plants.
