Cannabis & Grow Room Odor Control

Remove odors from growing cannabis, naturally and safely.

Cannabis Farms & Grow Room 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.

To combat the odors and fines that come with them, Ecosorb offers natural and effective cannabis odor control solutions for green rooms, grow rooms, and more.

Cannabis Odor Solution Challenges

Finding an effective cannabis odor mitigation 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.
  • 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

Frequently Asked Questions

What is Ecosorb CNB 100?

Ecosorb CNB Formulations are a natural odor eliminator designed for cannabis grow room, greenhouse, or processing facility odor control. It’s most commonly used as a liquid concentrate and delivered by vaporization mist around exhaust fans to scrub odors from escaping air. CNB 100 includes no masking agents, synthetic perfumes, harmful chemicals, VOC’s, or unsafe ingredients.

How does it work?

Our blend of natural plant oils eliminates odor-causing chemical compounds in cannabis — including cannabinoids, terpenes, and sesquiterpenes — without the drawbacks of other odor mitigation techniques. By breaking down odor molecules, it removes all smells from the air. Learn more about the science behind odors and CNB 100 in our helpful e-book.

What would I need to equip my facility?

Additionally, the distribution of Ecosorb requires no added water, thanks to advanced Vapor Phase technology. You just need the dispersion equipment and Ecosorb CNB 100, designed, engineered, installed, and maintained by Ecosorb’s odor control experts.

How is it different from carbon filtration?

Carbon filtration is used inside a facility to scrub air of odors. Ecosorb CNB 100 solutions are used outside a facility to eliminate remaining odors from escaping exhaust. When paired together, the combination effectively eliminates all odors.

Does it smell? Will my neighbors know I’m using it?

Because it is made from natural plant extracts, the aroma produced by CNB 100 is natural-smelling. However, as it works, CNB 100 eliminates all odors at the molecular level, including those from the product. What you’re left with is no detectable odors.
