Why Use An Air Extraction Kit?

Plants consume CO2 and release humidity. At the same time, your grow lights and other hot bits of kit are increasing your grow room temperature.

So you need to draw out hot, stale, humid, CO2 depleted air, and replace it with fresh, cooler, CO2 rich air.

This is what’s known as air exchange. In each system, you need:

A fan: draw air out

A filter: to remove odours before air is extracted

Ducting: to vent air where you need it


The beauty of an extraction kit is that you don’t need to worry about sizing everything up. You already know your carbon filter, fan & ducting will fit together. It’s the easiest answer to air exchange.


How To Use

1. Connect the fan to the carbon filter with a length of ducting
• Place a clip on either side of the ducting
• Connect one end to the carbon filter, the other end to the fan

2. Place a length of ducting to the other end of the fan
• Again, first attach the ducting clip

3. Position your filter
• Either hang it with a heavy duty chain, rope ratchets or stand it on a carbon filter frame
• The loose end of the ducting will need to be out of your grow space


We Recommend

Position your filter near the ceiling of your grow room, as hot, stale air will rise.

Create intake holes near the base of your growing space so your plants get a constant flow of fresh air to your plants.
