Cannabis Odor Control

Remove odors from growing cannabis, naturally and safely.

Cannabis Cultivation Odors

The strong odors produced by growing cannabis can be difficult to manage. Described as pungent, skunky, floral, fruity or even “sewer-like,” many neighbors label these odors a nuisance. Created by the plant’s essential oils (terpenes), odors are strongest when the flower is budding. Some odors from cannabis farms have been detected more than a mile from their source.

Complaints of cannabis odors have increased in some areas by as much as 87% since growing marijuana became legal. In Denver, 30% of odor complaints are cannabis-related. Local governments and clean air agencies are now enacting laws and issuing fines (in the tens of thousands of dollars) to limit odors.

Cannabis Odor Solution Challenges

Finding an effective odor removal method is challenging.

  • Most municipalities now restrict how commercial cannabis grow operations handle odors.
  • Large-scale ventilation systems that pump untreated air outdoors can be prohibited in some urban areas.
  • Industrial filtration systems can be costly to install, operate and maintain.
  • Enclosing a greenhouse can cause overheating and harmful rising of humidity, making greenhouse odor control more difficult.
  • Some grow room odor control solutions require the use of water to distribute, adding additional costs and equipment (especially in areas of water conservation)
  • Multiple partners are often needed for equipment, materials, setup and maintenance
