Well, there are many different brands on the market today but without the right buyer guide, ending up with a low-end product is always a possibility. Fixed ACs can be costly in your pocket. However, this is not the only reason why portable is better than the other types.

Urban dwellers who live in apartments may find it a little tricky to install these gadgets on their walls due to city regulations that are a bit strict. So, a portable ac for grow tent is always better because you can move it around the house to a station deemed fit inside an organic garden.

Choosing the Right Portable Air Conditioner for a Grow Room and Grow Tent

Now, with your mind fixated on finding the best item for your gardening needs, a good choice is not going to come easy. It goes beyond portability. Think about the efficiency of an air conditioner you want to buy, not to mention something that is good for the money.

The following tips should help you choose the best product for grow tent and room:


Home gardeners align themselves with different brands for one reason or the other. It is not just a case of brand loyalty. Favorite brands are trusted by many because they have been tested and proven beyond any reasonable doubt as the best in the market.

You might want to get hold of the little-known brand because it is cheap, but it may come with the disadvantage of poor quality. It is thus advisable that you go for a brand with a proven record of customer satisfaction.

However, there are cheaper options that are worth the money. Buyers are thus encouraged to do some homework about brands that are available for sale on platforms such as Amazon. Moreover, when doing this, weigh into issues of durability as well. [1]

Type of Air Conditioner

It is another vital thing to consider before settling on an AC that you believe is good for the money. There are three main types namely portable, split, and window AC. Now, basing your decision on this post, mobile products are the most ideal.

Seasonal Energy Efficiency Ratio (SEER)

Don’t worry when you find labels like EER. It means the same thing as a SEER. You may want to ask, what does this say? You would not want to buy grow room ac units that would consume large amounts of energy hence leaving you with hefty power bills to pay. For this reason, a closer look at SEER rating is an important determinant when choosing an ideal appliance for a grow room or tent.

EER/SEER denotes energy efficiency. It is advisable that you buy one that has a higher rating because it has higher productivity compared to those which have a lower ERR rating.

Look at the Filter

Toxicity in the air can contribute to the death of plants in a grow room. It is for this reason that there are filters in ACs to purify the air. By extension, polluted air is equally harmful to your health as a grower. So when choosing a good product, the right decision should come alongside filters.

Control System

Even though most home gardeners overlook this feature, it is a significant thing to consider lest you end up buying one that has been overtaken by improvements in modern air conditioners. The Control unit enables you to set the right conditions favorable to plants in a grow room.

On the control system, there are things like timers that you can use to auto-set an AC to switch off when hot or cold air reaches unacceptable levels.

Ventilation Features

A good air conditioner for growing tents should allow for maximum airflow. On this premise, it is crucial to buy one that has adjustable airspaces. The good news is that you can find one with automatic louvers on the market so that you do not have a check on your installation every time.

Electrical Installation Compatibility

Manufacturers try to outdo each other when it comes to providing buyers with a range of options to choose from when buying air conditioners. Electrical features such as voltage input/output, power codes, and type of plugs you need for grow room air conditioner installation are some crucial things to consider before settling on a product of choice.

Look at the Product Warranty

Most people overlook this crucial after-sales provision when buying an air conditioner. However, think about it this way; what if you buy an AC only to realize it is faulty? Inexperienced indoor growers will most likely go for a new one instead of making the most out of the product warranty.

A warranty is there to cover you with original replacement or repair costs if a product is faulty. After learning about the usefulness of guarantees, an excellent choice should be one that comes with the best warranty terms.

For example, two years product warranty means that the manufacturer will take care of repairs/replacements and costs arising from it.

How Does a Portable Air Conditioner Work?

On a hot summer afternoon, you would probably want to feel fresh air circulate in the living room. Plants need this feeling too, and with the best portable air conditioners, you are not far from it. However, something most people do not understand is how this stuff works.

The information available online can be pretty confusing. However, according to the law of energy conservation, it is impossible to create or destroy energy. It exists in nature. Now applying this to the air conditioning in a grow room, it means you will only be diverting air to another place or changing its form.

A typical AC is made up of three major parts namely:

  • Evaporator (This will be on the inside of the growing garden)
  • Condenser (This part will be on the inside of a grow tent)
  • Compressor (Also on the outside of the house)

How it works:

  • Hot or warm air inside the grow room gets into the grille through the suction
  • A liquid coolant circulating in chiller pipes cools it (You can relate this to the same principle that in refrigeration). At this stage, there is a dehumidifier that extracts moisture from the air passing over the coolant
  • The next step that the air goes through is a heating element (typical of heater fans)
  • The fan pushes the air back into the grow room via the grille. Incoming air is thus crisp and fresh.

Things to Note During Cooling

The liquid coolant (evaporator) vaporizes fast as it takes heat away from the outgoing air. The hot air is expelled out of the room into the surrounding when it mixes with atmospheric air. There are metal plates on the outer unit of an air conditioner that further dissipates the hot air. The fans in the group speed up this process.

How to Install a Portable Air Conditioner in Grow Tent & Grow Room

Once you acquire the best portable AC for your garden, the next thing to do is install it. It should not be something that rakes your brain. It is a pretty simple exercise but first; there are prerequisites. They include the following:

  • It is imperative to station this essential equipment for your grow room near a power source such as a socket. Manufacturers of air conditioners discourage the use of power extension codes for other home appliances. It is because using any other connection cable or plug might cause power overload, damage to the air conditioner, or even a fire outbreak
  • Keep the AC out of reach of children. It is a crucial safety measure.
  • Another thing that you must take into consideration when installing a portable AC is a grow room with proper ventilation. While this gadget is meant to clean the air in the surrounding, a stuffy place is likely to compromise the air quality in your grow tent.
  • Lastly, go through the user manual that usually accompanies every product you buy from Amazon or anywhere else

Now, after taking note of the prerequisite conditions above for setting up, it is time to plug and switch on your portable air conditioner for grow room. Choose a suitable location in the grow tent.


People ask many questions when looking for the best product to buy, and it is not just because they do not want to make mistakes. An excellent portable AC should be able to serve you for longer. The following questions and answers thereof should be able to address most of your concerns:
