Marijuana Grow Room Ventilation and What You Need to Know

February 11, 2019

Similar to any other living thing here on earth, plants need air to breathe. Nevertheless, it is important for cannabis plants to get adequate air and ventilation for it to grow well, preventing suffocation and stress. That is why as a cannabis grower it is vital to be informed about this, to ensure that the plants grow as best as possible.

In this article, we will be looking at the basics of establishing techniques for air ventilation. We will also tackle the consequences of poor air ventilation and the symptoms of when this is occurring.

Why is Air Circulation and Ventilation Important for your Plants?

As you know, air is essential for plants to breathe, supplying its system with enough carbon dioxide to be used in other processes like producing food efficiently. That is why neglecting this process will cause immediate problems not just to the plant but also to your bud production itself. You’ll expect less induced buds when this parameter is compromised as well.

Aside from that, air circulation is also important because it protects the plant against pests such as fungus gnats and spider mites. Making sure that you have an even air distribution for your cannabis system means that you’ll get less exposure to moisture where pests tend to thrive. Not only will it help with these pests, but it will also help you resists molds and mildews which also thrive in moisture rich environments.

Maintaining air circulation and ventilation around your plants will also stabilize your system. It will strengthen it, making it not as easily ruptured with powerful winds.

Ventilation has a close relationship with humidity and temperature. Thus, when one parameter is altered, it is expected that there will be a change in air circulation of the surrounding plant’s environment.

How to Ventilate your Indoor Grow Room?

There are a number of ways that you could employ ventilation with grow rooms in order to assure that your space has great ventilation for your cannabis plants. The following are examples:

Exhaust Fans:

Fans are an excellent way to produce and maintain the air circulation around your cannabis plant system. Nevertheless, it is important to make sure that the plants receive a slight breeze. Some small growers employ oscillating fans over the canopy and into the sides of their plants to ensure that every part of the plants get surrounded by air as needed.

However, be careful when doing this. Never put on too much air and power over your plants. This will cause the leaves of your plants to claw.

Ducting:

As needed, air should be exchanged every 1-2 minutes to maintain the temperature and humidity surrounding the room. The ducting should be positioned and connected to the bottom corner of the grow tent. That said, the ducting should be straight and secure all over the place. It should be connected to an external source of air preferably a window or vent for the release of air.

HVAC system:

Similar to heating and cooling systems employed in your homes, you could also install these systems into your cannabis gardens. This is the most efficient way to take control of the temperature and humidity of your cannabis systems directly. Though a bit expensive, these systems are proven to be precise.

 

The Ventilation Cycle

When the lighting system is turned on, it will generate an increase in temperature. Thus, the ventilation should cope with this increase using fans. Nevertheless, the system should maintain a room temperature of 26 degrees Celsius for the plants to grow.

At night, when the light is mostly turned off, the ventilation is adjusted and reduced to a minimum. This function is done to ensure that the temperature is still maintained to what it should be.

To prevent mold growth, it is important that these systems be powered 24 hours a day. These systems should be maximized during the flowering stage where cannabis plants are more at risk to molds.

 

Noise Reduction on this Ventilation Equipment

Since this equipment may be a bit noisy for some growers, there are some ways you can reduce the noise it produces. These include the following:

  1. Use soundproof air ducts for both outtake and intake
  2. Using carbon filters to lessen the noise that is generated by the airflow.
  3. Enclosing your equipment with wood or metal casing to reduce the noise that it produces.

 

Controlling the Odor of your Cannabis Plants

The best way to prevent the spread of strong cannabis smell is to employ carbon filters. This uses a carbon scrubber that works on removing the smell of cannabis upon going out into the exhaust. Though installation can be a bit complicated, this is the most efficient way to control the smell that your cannabis plant generates. Making sure that your area is kept closed with no leaks is essential to prevent the escape of smell from your cannabis system.

Regardless, if you don’t have enough money for installation of these carbon filters, you could spray around perfumes or anything that masks the odor of cannabis plants especially on important events and occurrences where it needs to be done. Though not a permanent solution, this has been proven to be helpful to at least prevent the strong scents of cannabis plants to get exposed readily outside the planting premises.
