One common question we’re asked here at is if you place the carbon filter / fan inside or outside the grow tent. The answer is simple – you can do both!

The main concern is to make sure your extractor fan pulls all the air from your grow room out through your carbon filter, it doesn’t really matter which way it is setup as long as the airflow is going through the filter.

Top tips – reduce noise and make it smell nicer!

Sometimes carbon filters and extractor fans can make a lot of noise, here are some top tips to follow:

  • Mount your extractor to a wall for less vibration
  • Alternatively hang your extractor fan inside the grow tent alongside the filter
  • Place a spongy air freshener inside your filter for a pleasant smell throughout your grow room
  • Upgrade to acoustic ducting for lower vibrations
