The Importance of Good California Commercial Grow Room HVAC Design

If you’re an avid pot grower living in California and are looking to put in a commercial grow room, you’ll probably have some say in its design and setup. One major aspect of the grow room design is the HVAC system you choose; it will play an important role in the cultivation of your crop and how much profit you end up with at the end of the year. Here’s what you need to know about California Commercial Grow Room HVAC Design and why it could be the most important part of your commercial grow room!

Ideal Commercial Grow Room HVAC Design for Marijuana

Commercial grow rooms need to achieve optimal temperature, humidity, and ventilation levels to help their plants thrive. Unfortunately, maintaining the ideal levels during each stage of growth can be difficult because marijuana is an especially finicky plant. Despite that difficulty, the right conditions can be created through specialized HVAC systems. Let’s take a look at three factors that contribute to plant growth and what happens when the right environmental conditions aren’t maintained.

It’s important to understand how temperature affects marijuana growth. Marijuana likes temperatures that are between 70-85 degrees Fahrenheit. At 80 degrees, marijuana will grow quickly and have dense flowers. While heat helps create strong marijuana plants and flowers, your commercial grow rooms should not be too hot because it could lead to the growth of bacteria, molds, and fungi that may harm your cannabis crop. Excess heat can also lead to the claw or big dark spots on flower petals

Temperatures that are too cool will also negatively affect your crop; if you grow at 70 degrees or lower, you’ll get long and lanky plants with less resin production. The right temperature is essential for cultivating high-quality marijuana.


Humidity is one of those elements that cannabis growers have to be careful with, as it can help or hinder production depending on the stage of growth. For example, germinating your seeds in a humid setting—around 70% to 80% humidity—will cause them to produce strong roots later in life.

But aside from germinating seeds, lower humidity is better for most other periods of growth, such as the vegetative and flowering stages; humidity should be kept at 40% to 70% during the vegetative stage and 40% to 50% during the flowering stage. If there’s too much humidity in the air during these periods of growth, your plants could suffer from mold or mildew, which will reduce both the quality and yield of your crop.

Air Flow

Marijuana plants also need proper air flow in order to thrive. If marijuana plants are not given enough ventilation, they will suffer from issues like disease, pest infestations, and stunted growth. It is important to plan out your cannabis grow room with an eye toward proper ventilation before any seeds are planted in soil or clones are stuck into Rockwool cubes. Proper ventilation and airflow should be implemented right from day one, rather than an afterthought that is addressed much later in your grow room setup when symptoms begin appearing.
