How to Keep Cannabis Cool Using HVAC Systems for Growing?


Cannabis has several needs which one needs to fulfill in order to make it grow. The HVAC (Heating, Ventilation, and Air Conditioning) system is essential for cannabis to grow. Cannabis is known for its pungent smell or odor, which everyone tries to avoid. This is also because of the high humidity level.

However, if we keep the odor aside, there are several other needs that can only be fulfilled using HVAC.

Understanding the Environment

It is important for us to understand that cannabis is a tropical plant. If you try to grow a tropical plant in conditions that are arctic in nature, then your plant will obviously not grow. Tropical plants might need a warm temperature and immense humidity. However, it might shock you that they need a lot more cooling than other plants, and for that, HVAC is very important.

What might be the logic behind it? The logic is that cannabis needs immense amounts of light. This light tends to create a lot of heat energy which makes the room really warm. Warmer than one might even want. So, this creates a need for cooling down the plant, for which HVAC is required if we want the plant to grow without harming it in any way. Another reason why one absolutely needs an HVAC for growing cannabis is that the plant is grown in a room with very few windows. It is a plant that is a high-dollar crop. So, they have to rely on HVAC for cooling. To gain some consultants, you can even visit the site

Meeting the Needs of the Plant

There are several things that cannabis craves. Just like it is really important for us to keep cannabis cool by amending the temperature and providing enough cooling. The plant also needs the right flow of air. The cooling allows stem growth, but the airflow is really important for the overall growth of the plant. This air is significant because it takes away all the water from the plant. You might need more than one heating, ventilation, and air conditioning system for your plant if you want to make sure of this. You need to ensure that the carbon dioxide levels do not drop below or exceed a given level.

For that, again, the heating, ventilation, and air conditioning system is necessary. At one point, you might want to grow the crops in different rooms. That is because if enough cooling is not provided to the plant, signs of molding can be seen. The crop can fail due to the presence of different diseases and insects as well, which would take over because the cannabis was not cooled enough. So, in order to avoid that, you can set up the plants in different rooms so that if one room of cannabis gets affected, the rest of the plants are not affected. This way, you would not have to face a huge loss as well. Moreover, for this, you would need several heating, ventilation, and air conditioning systems which would eventually incur a huge cost for you.


It has been established that understanding the environment is absolutely necessary. Without the proper knowledge, one cannot progress in this industry. One might have to invest a lot in the beginning, but the return on investment is really high for this plant as it is a high-dollar crop.
