The Basics of Climate Control

Cannabis plants can be delicate creatures – too hot and they’ll wilt, too cold and they’ll die. That’s why climate control is crucial to growing cannabis plants. By controlling the temperature and humidity in your grow space, you can create the perfect environment for your plants to thrive.

If the temperature and humidity levels fluctuate too much, the plants will not be able to grow properly. Additionally, climate control helps to prevent mold and mildew from forming on the plants.

Other important environmental factors for cannabis plants include light and air quality. If you’re growing indoors, it’s important to replicate what the sun would naturally provide your plants in the wild.

With the right light setup and schedule, you can maximize your plants’ growth and get higher yields when harvest time comes. Air quality is another significant factor to consider, given how your plants will need enough CO2 and oxygen to thrive.

Creating Your Climate Control Setup

With all the different options on the market, there’s practically an infinite amount of ways you can create your growing setup. Our goal is to educate you on all of the options and synthesize them in a way that makes the process seem a bit more digestible.

Depending on the size of the space you have available, your budget, and your experience level, certain products are going to appeal to you more than others. We’ve tried to include several price tiers in each review article so that everyone can find something that meets their needs.

If you start to feel overwhelmed, just remember the core aspects of your setup: light, airflow, nutrients, temperature, and humidity. There are also kits that come with all the elements you’ll need to get started: this can be a great option for beginners!


One of the most important and obvious factors you must provide your plants is light! Just like any other plant, your seedlings are gonna need plenty of light in order to grow to their maximum potential. Finding which grow light is right for you depends on several factors, including the size of your grow room and your budget! Most growers choose LED lights, given that they produce less heat than other types of grow lights on the market. You can also decide which spectrum of light you’d like your plants to be exposed to.

Air Circulation

The next major key to growing healthy cannabis plants is ensuring that the air is circulating freely around your grow space. Plants need both oxygen and Co2 to survive, so you’re gonna need to find a grow tent fan that suits your needs. There’s many different types of fan, the most popular varieties would probably be oscillating fans and inline fans. Once again, what’s best for you is gonna depend on the size of your space, the configuration of your setup, and your own personal needs!

Air Quality

Not only does the air in your grow space need to be circulating, you need to make sure that your plants are getting enough fresh oxygen. The easiest way to do this is by installing a carbon air filter! These filters will allow the air to stay fresh and healthy for your plants all growing season long.

Temperature Control

Next up is making sure your plants are in a suitable temperature range. Depending on the strain, you can get away with slightly hotter or colder temperatures, but generally: cannabis plants enjoy warmth. For this, you can just install a grow tent heater and let it take care of this environmental factor for you. Depending on the size of your space, you may need a more or less powerful heater, but we’ve included a variety of models in our review to cover grow spaces of all shapes and sizes.

Humidity Control

Humidity control can get a little tricky if you’re having to constantly monitor and adjust the levels manually. For this reason, humidity controllers have become increasingly popular in the growing community. All you have to do is check the meter and let your grow room regulate itself! It’s important that your grow room has the right amount of humidity: too much moisture can end up harming your plants and causing mold growth.

Co2 Regulation

Lastly, it’s important the air in your grow space has a proper ratio of oxygen and Co2. Because controlling this manually can be a bit tedious, many growers have turned to Co2 regulators to help automate this part of the growing process.

Indoor Vs. Outdoor Environments

Indoor cannabis growing offers growers a great deal of control over the environment. By controlling the environment, growers can ensure that their plants get the precise amount of light, water, and nutrients they need.

They can also control the temperature and humidity, which are critical for the health of the plants. Outdoor cannabis growing, on the other hand, is much more subject to the whims of nature.

While growers can take some steps to control the environment, they ultimately have to rely on the weather and the natural light cycles to provide their plants with the conditions they need to thrive.

This can be a challenge, especially in areas with unpredictable weather patterns. There are pros and cons to both indoor and outdoor cannabis growing. Indoor growers have more control over the environment, but they also have higher overhead costs.

Outdoor growers may have more variable results, but they can also save money on costs like electricity and water. Ultimately, it’s up to the grower to decide which method is best for them.
