cannabis ventilation system - indo expo

Carbon Filters

A tubular device, usually located in-line near the exhaust of a ducting system, which uses activated charcoal to “scrub” the air. Carbon filters can filter dust, pollen, harmful spores, and other microorganisms from the air, as well as remove the compounds in the air that cause cannabis’s signature smell.


Also known as chilled water systems, these devices are specifically designed for indoor cultivation facilities. Using chillers allows growers to eliminate ductwork (where molds can hide) and completely seal their environment, maximizing control of the environment and eliminating odor escape.


Cooling is important to avoid killing your crop. Lights, CO2 generators, body heat, and cannabis plant’s natural processes all build up heat in the growing area, and this heat can be toxic for your plants. HVAC cooling systems are essential in any cannabis grow operation where the indoor temperature may climb above 80 degrees Fahrenheit. Otherwise, fans, air circulators, or venting should be used to control heat as these methods are less likely to dehydrate the air around your hungry plants.


A system of ducts that strategically move air throughout your grow space. Proper air circulation is essential for plant growth and the reduction of microorganisms and pests in the grow room. Ducting gives the grower maximum control of the indoor environment, including temperature, CO2 levels, humidity, and odor.


Fans serve several purposes in the grow room. They circulate CO2, allowing every plant to breathe easily. Fans also help to keep the temperature consistent throughout the growing area. Finally, moving air simulates a small breeze which causes seedlings and smaller plants to stress slightly while growing. The plants, forced to adapt, grow thicker and stronger enabling them to hold more weight.


Proper heating is necessary to maintain ideal growing temperature on colder days. Cool temperatures can stunt growth, inhibit nutrient uptake, and reduce evaporation through the plant’s leaves. Lighting alone may provide small spaces with adequate heating. Larger grow rooms require supplemental heat in the form of an HVAC central air system and/or portable heating devices (space heaters for cold corners.)


A device is said to be ‘in-line’ with a closed system when it is placed in such a way as to modify that system without interrupting its normal operation. For example, a carbon filter that takes in air from a ducting system on one side, cleans the air, and then exhausts air back into the ducting system would be an ‘In-line filter.’ The filter does its job while the ducting system continues its operation unimpeded.


A colorless, unstable gas created when oxygen interacts with electricity or UV light. Ozone reacts with microorganisms as well as the volatilized compounds that give cannabis its signature smell. When either come into contact with ozone, oxidation occurs that kills the undesired molecule and converts the ozone to oxygen resulting in clean air with a pleasant aroma.

Smell Kill

There are many options available to reduce/eliminate the odor of cannabis in your operation. A combination of ozone generators, inline carbon filters, HEPA filters, aggressive ducting, and/or scent diffusers have all been used with some success.

Supplemental CO2

Carbon Dioxide is fuel for photosynthesis making it necessary for the growth of your cannabis plant. Though the air around us carries more than enough CO2 for a plant to convert to sugar and O2, this is one instance where more is better. CO2 generators come in a variety of sizes, methods, and levels of efficiency to supplement your cannabis operation with carbon dioxide.


Ventilation is necessary for a grow room to move hot, oxygenated air out and cooler air in that is rich in CO2. Small, amateur grow operations can survive on a patchwork system of fans and open windows. Serious growers need to invest in a ducting system with temperature control to ensure consistent growth.
