So, what does this mean?
Plants, basically, need adequate temperature and indoor humidity. When managing the climate inside your grow room, it is very important to consider these two factors.
One thing that you should remember, however, is that the temperature and humidity that your cannabis plants will be subject to inside your grow room will depend on the weather in the particular region where you live.
While you can have many options to resolve the climate issues that are associated with a grow room, using ductless mini split brings you many advantages that you can’t get from other systems.
In this article, you will learn about the most common climate challenges in a grow room environment, the various cooling options used, and the reasons why using a ductless mini split system is the best way to go.

Grow Room Requires Proper Temperature
Plants react differently to different temperatures. Some plants can grow even in extreme weather condition, but typically, high or low temperature affects the growth and production of marijuana plants. The best way to get a better grasp of this idea is to understand that there are plants that thrive in warmer environments and there are plants that naturally flourish in cooler environments. When the climate is not conducive to the growth of a particular type of plant, its growth is usually stunted, or worse, it dies.
A temperature that ranges in between these degrees is fine, so it’s up to you, although most expert growers recommend 65-75°F for the temperature. This gives room for a little variance—enabling a still ideal temperature for the plants even if the indoor climate dips a little bit lower or higher.
The Right Amount of Humidity
Aside from temperature, the humidity level inside the grow room is very critical to the growth of your plants. If you live in areas where the cold weather is typically harsh, you’ll have to consider that the humidity inside your grow room will be very high. A high humidity makes the air feel dry due to lack of moisture in the enclosed environment, and this is not good for the plants.
With lack of moisture in the grow room, the plant is denied with water that it takes from air and its growth is stunted as a result. Plants may be able to adapt to a colder environment, but too much humidity will dry them out and they would eventually die.
Humidity pertains to how much water vapor or moisture is in the air. When talking about humidity, just think of water in a gaseous state that circulates invisibly in the air. Humidity affects all living things, which of course include plants.
To give you a better idea, let’s first start looking at how humidity affects the human body. Afterward, we’ll proceed discussing why it’s almost the same way with plants.
Now, remember that our body sweats as natural way of cooling itself. When our body perspires, our skin pores open and it releases some water and salt, which is what we call the sweat. Our sweat carries some heat from our body, allowing us to feel cool and comfortable. When the humidity is high, it means there is already too much water vapor in the air and it can no longer absorb more. In this case, our sweat that carries some heat evaporates more slowly than needed. This explains why during high humid days we feel the air being sticky. We also feel hotter because our sweat can’t evaporate faster from our skin and the heat that is supposed to be carried away stays. Now, when the humidity is low, we feel cooler but we easily get dehydrated because the sweat in our body evaporates faster. With low humidity, the air feels dry.
How does this relate to plants?
Basically, the same thing applies to plants. High humidity and low humidity are both not good for plants just as they are bad for us.
How does this affect the growth of plants?
As for the plants, remember that they go through a process called photosynthesis (basically, to make their own food) in which carbon dioxide is an important element, aside from water and sunlight. During this process, plants absorb the carbon dioxide from the atmosphere by opening its pores in the leaves. When they do, they release some moisture or water vapor into the air. This is called transpiration, a process when the water that comes from the pores in the leaves of the plant evaporates. You can imagine this as being similar to the perspiration that happens to us when we sweat.
When the humidity inside the grow room is low, the amount of moisture that escapes from the pores of the plant leaves is greater. Losing too much water this way makes the plants dehydrated. As a result, there’s a very good chance that the plants would wilt.
As a natural reaction, the plants usually close their pores to prevent losing more water. The problem is, when the weather becomes too hot and the pores is closed, the plants would have too many water vapor inside and it would not be able to absorb carbon dioxide and go through its normal photosynthesis process.
When the humidity inside the grow room is high, no water would evaporate from the pores of the leaves of the plant. This causes a problem when the temperature is also high because the plants would not be able to lose water to cool themselves.
Climate Control is Essential
As is commonly practiced, the temperature and humidity inside your grow room can be controlled through proper climate management. This will enable you to grow your plants no matter the weather and enjoy the endeavor all-year-round without worrying about the right season to grow plants.
Managing the climate inside the grow room means controlling the temperature and humidity to a point that is suitable and conducive to the growth, development, and production of plants.
When managing the climate inside the grow room, the main challenge is to simulate the type of climate that the plants normally get outside. This means that the temperature and humidity levels inside the grow room environment must be as close to the ideal temperature of the outdoor environment where the plants usually grow and develop.
Typical Cooling Options for a Grow Room
Cooling the environment is one of the critical tasks to do when maintaining a grow room. On top of other considerations, having the right cooling solution determines the overall success of your climate management in your grow room and ensures the health and productivity of your plants and crops.
When choosing the right cooling system for your grow room, don’t forget to consider the size of the space. This is important so you would know the right cooling capacity that you would be looking for.
When you go out in the market to select the right cooling system, you will find that you can have too many options. These systems vary in type, size, efficiency, capacity, and performance.
Some of the most common cooling solutions that are used in a grow room are fans, dehumidifiers, chillers, and evaporative coolers. The chillers are either water-cooled or air cooled, and both help absorb the heat that builds up inside the grow room.
With the evaporative cooling system, the choices include a solution that provides mists into the air which are meant to be vaporized, and a swamp cooler that uses a fan system that blows air into a wet media to initiate an evaporation process, which in turn helps in dropping the temperature inside the grow room environment.
Keep Your Grow Room Cool with Air Conditioners
Essentially, one of the most effective ways of climate control management for a grow room is through correct air conditioning.
Take note that being a sealed environment, heat is naturally the biggest concern. In many ways, this makes air conditioning the most logical option. It will not only create the right temperature inside the grow room but will also help exhaust the heat that is generated by the many equipment that are used inside, such as the lighting system, pumps, blowers, generators, ballasts, and many others.
With proper air conditioning, the temperature and humidity issues will become the least of your concerns when growing plants indoors.
When it comes to air conditioning systems for grow rooms, some people use portable air conditioners and window AC units, but what’s proven to be the most effective is the ductless mini split system.
Why Ductless Mini Split System is Your Best Option
Ductless mini splits, which consist of an outdoor compressor unit and one or more indoor air handlers are flexible AC units that do not require any ductwork, making them very easy to install in your grow room. Compared with other air conditioning systems, like a window unit or central AC system for example, a ductless mini split is very flexible and you would not have any issues with it whatsoever, especially when it comes to the location of your grow room.
Available in single-zone and multi-zone configurations, a ductless mini split is a perfect system for your grow room especially if your growing environment is detached from your main house where the network of HVAC ductwork is installed.
A ductless mini split also works both as an air conditioning system and a heat pump solution. This makes it ideal for a grow room especially if you’re looking for a system that will enable you to effectively heat or cool your grow room regardless of the season or weather.
Grow rooms can also benefit from ductless mini splits’ highly advanced system. One of their powerful features is the capability to heat the room even when the weather outside drops to subzero temperature.
Moreover, ductless mini split systems have better filtration technology and are more environment –friendly than the rest of other systems. They have capabilities not only to filter out airborne contaminants but also ensure that molds and bacteria would not develop, which is very essential to the maintenance of the grow room.
