Why Grow Room Ventilation Isn’t Enough

Posted by Brenda Roy on Oct 15, 2019

why-grow-room-ventilation-isnt-enoughAs a marijuana grower, you know that providing the perfect environment for your plants is important for the quality of your finished product. They need the right temperatures, humidity, and airflow. On top of that, they need fresh air. Photosynthesis can’t happen without a good supply of CO2. If you’ve been doing this long, you probably have a great grow room ventilation system to pump in outside air so your marijuana stays healthy and potent. 

However, ventilation can cause its own problems. All of that “fresh air” can introduce toxins and air-borne pathogens to your grow room that could threaten the health of your plants. In conjunction with your ventilation system, you also need an effective purification and filtration system to ensure good air quality. Without these measures, all of your efforts to control temperature and humidity will be pointless. 

If your grow room ventilation system does not yet account for air quality and purification, here are some of the harmful pollutants you may be subjecting your marijuana to. 

Bacteria

Just like humans, plants can contract bacterial infections too. They are harder to diagnose in plants, however, because the signs are so similar to other plant diseases. For instance, spotted and dying leaves may indicate a bacterial infection or something else. Luckily, you’ll never have to worry about identifying a bacterial infection if you use proper air filtration methods with your grow room ventilation.

Insects

You might think growing indoors prevents any pest problems, but if your grow room ventilation system doesn’t have a way to keep bugs out, you would be wrong. 

Indoor plants are especially susceptible to the minuscule spider mite which travels by wind and can easily come in through your ventilation system if you don’t have a good filter. Once inside your grow room, these critters eat your marijuana leaves, and then spin webs and lay eggs all over your plants. Because they are so small and stubborn, an infestation is very difficult to get rid of before they destroy your crop. 

Molds and Fungi 

Air-born mold and fungi spores should be one of your worst fears as an indoor grower. Mold and fungi love a moist, humid atmosphere with plenty of organic matter. Your grow room is their ideal habitat. Once they establish themselves on your plants, it doesn’t take long for them to give your plants rotting diseases that kill them off. 

There are so many types of molds and fungi that can get into your grow room if you aren’t careful: black spot, botrytis, powdery mildew, Fusarium. Using proper air purification equipment with your grow room ventilation system can stop all of them in their tracks. 

Pollen

If you suffer from seasonal allergies, you know how easily pollen travels through the air. While this is a low-risk issue for marijuana growers, it’s still good to be aware that invasive pollen can cross-pollinate with plants and affect your product. Especially if you enjoy breeding new plants, unintended pollination can alter the results you were looking for.

Volatile Organic Compounds

Volatile organic compounds, or VOCs, are chemical compounds in gas form. Those harsh chemicals like fungicides and insecticides can be dangerous to plant life. At the very least, you don’t want your marijuana plants absorbing chemicals that may affect the quality and safety of your product. 

There are many conditions to take into consideration when you set up a marijuana grow room, not least of all general air quality. Good ventilation is not enough. Just like you would use a water filter to purify water, an air filter or similar purification methods should be incorporated into your grow room ventilation.
