Good air circulation is essential for growing cannabis! This basic setup shows all the essentials you need for a proper grow.

These filters use ‘activated’ carbon in order to draw the cannabis smell from the air via a chemical process that neutralizes the odor completely. A fan with a high m3/min ratio is used to draw/pull air through the carbon filter, which then ‘scrubs’ the marijuana smell away leaving the environs of your indoor grow space odor free. You can connect these types of filters to the inline exhaust system used to cool your high intensity discharge (HID) lighting or use them independently to help control the cannabis smell in your grow space.

Fans and filters dont have to be huge, light weight carbon filters like this Can-Lite filter can easily be installed in virtually every grow space.

It’s highly recommend to use a short length of exhaust ducting between the fan and carbon filter. Utilizing exhaust ducting will help to avoid the fan vibration passing through to the carbon filter. The fan’s vibration may perhaps cause the carbon at the top of the filter to settle, which would allow air to move through the filter going unprocessed. Even a piece of flexible exhaust ducting a few inches in length placed between the fan and carbon filter is adequate to keep this predicament from transpiring. Regardless of which of these methods you choose to utilize, keeping the cannabis smell under control is always an important aspect to consider when contemplating starting an indoor cannabis garden of your own.
