Now that marijuana cultivation and sales are legal in Illinois and many other states, growers across the nation are expanding production. As a member of this budding industry, you’re positioned to overcome unique problems. As a grower, you know cannabis odor is an issue that affects small and large operations.
How do you maintain optimum commercial cannabis production and keep a handle on greenhouse odor control?
Greenhouse Odor Control: 7 Smart Ways to Manage the Problem
As the cannabis industry takes off, the fragrance of marijuana crops can result in unexpected problems. Some growers are facing lawsuits from complaining neighbors. Building owners might be concerned about long-term odor effects. These seven strategies help control greenhouse and grow room odors.
1. Keep the Grow Room Clean
The best odor control systems can’t operate effectively if you don’t take care of the grow room. Routine maintenance and basic housekeeping ensure a healthy environment that reduces cannabis odors.
• Wipe down all surfaces daily to remove traces of pollen.
• Clean up wilted and dead plant debris every day.
• Regularly clean cultivation tools and equipment.
• Monitor watering system performance to control humidity.
• Routinely change out air filters in ventilation and cooling systems.
High humidity and temperatures can turn grow room odor problems into serious air quality issues. Dehumidifiers and fans are important tools for reducing both.
2. Maintain Maximum Air Flow
Commercial greenhouses serve as great examples for cannabis growers who want to improve operations by improving indoor air quality. Even small setups benefit from the combination of exhaust fans and ventilation systems.
Measure your greenhouse space. Figure out how many cubic feet need ventilation. Use the numbers to choose equipment sized to work best in your space. Arrange different fan types and configurations for maximum air flow in and around grow tents, lights and tight spaces.
Constant air circulation controls temperatures, holds down odors and keeps crops healthy from seed to harvest.
3. Invest in Carbon Scrubbers
These air cleaners are considered basic equipment for eliminating odors in grow rooms. Activated charcoal carbon filters are available as pleated duct filters, pliable sheets and enclosed filter units.
Carbon filters are easy to install in all types of equipment. They destroy 90% of cannabis odors on contact, but they need to be changed out every two to four months. Carbon scrubbers promote healthy plant growth by significantly reducing airborne bacterial counts.
Try a combination of carbon filters and inline fans. Experiment with different setups in different areas of your operations. Carbon filtration works especially well at high points in the room where heat accumulates.
4. Consider Organic Biofilters
Many industries improve on-site air quality by controlling odors with organic biofilters. Agricultural operations, wastewater treatment facilities and chemical manufacturing sites are just a few examples.
Biofilters have practical applications for the cannabis industry too. They’re an eco-friendly alternative to other types of air scrubbers. Organic materials make the filters ideal for maintaining healthy grow room air quality. It’s a new technology for cannabis production, so be willing to experiment.
5. Track Plant Growing Phases
Develop different strategies for managing cannabis greenhouse odors by tracking crop growth patterns. Coordinate and adjust odor control techniques to work with these different phases.
• Seedling Phase – The first phase averages seven days. Seedlings thrive with plenty of fresh air circulation, but the young plants rarely cause odor problems.
• Vegetative Stage – Most cannabis crops evolve through the vegetative stage at a rate of three to eight weeks. Low-level odor control methods are usually effective during this growth phase.
• Flowering Stage – Over the next five to 16 weeks, flowering nodes develop trichomes with high concentrations of terpenes. Your strongest odor control techniques may still leave traces of cannabis fragrance in the grow room.
6. Don’t Count on Odor Absorbers
Odor absorbing gels and sprays aren’t recommended for controlling grow room odors. The products mask smells by replacing existing odors with different fragrances.
You might try odor absorbers during a crop’s final bloom phase, but don’t rely on them. Use them sparingly. Air fresheners can pose health and air quality risks.
7. Let Pros Purify the Air
Even the cleanest grow rooms develop problems that make odor issues impossible to control. Virus and bacteria can invade plants and contaminate the air. A faulty water system can leak and result in unhealthy mold growth.
When you face serious greenhouse issues that affect air quality, bring in a commercial cleaning service. Industry-certified technicians use heavy-duty air scrubber systems that eliminate odors and purify interior atmospheres. It’s the fastest, safest and most beneficial way to restore a healthy grow room environment.
