While mounting a split AC might take some time, this air conditioner from Pioneer comes with all the solutions that a grower might need such as a 16ft copper piping kit to make the process easy. When you get the package, you’ll get an indoor unit, an outdoor unit, an installation kit, and a remote controller. The outdoor unit is basically the compressor of the AC.

There are many different types of ACs which you need to consider when looking for the best air conditioner for grow rooms and grow tents. The split AC is one of the most common types of ACs which is seen all over the world, used mostly for regular room cooling purposes. The main advantage of using this is that split ACs generally tend to cover a much larger area compared to a portable AC and are cheaper to operate in terms of electricity consumption when you compare them with the traditional window ACs. Hence, these are the best air conditioners for grow rooms.

Buyer’s Guide: Things You Should Look for in an Air Conditioner for Grow Room

Now that you know which are the best options when it comes to air conditioners for grow rooms and grow tents, let us take a detailed look at some of the factors that you need to consider before you make the final purchase decision:

  • Cooling Capacity – You need to know exactly how much this AC can cool. Is the level of heat generated in your room more than what this air conditioner can cool? Count the heat generated in BTUs per hour vs the BTUs per hour that the AC provides and then you can come to a perfect conclusion. Generally, in a grow room, heat comes from three main sources: grow lights, CO2 burners, and dehumidifiers. Hence, you need to know exactly how much the AC can cool. Also, your room size plays a role in this. The bigger the room size, the bigger an AC you would require.
  • Electric Consumption: Another important consideration that you need to keep in mind before you purchase the best air conditioners for your grow tents and grow rooms is that you must know exactly how much electricity would the AC consume. Generally, smaller (portable) air conditioners tend to consume less electricity and window ACs tend to consume the most. Split ACs find a sweet spot between the two in most cases.
  • Size: The size of the air conditioner also matters. You need to see if there’s enough space in the room for you to place the AC or to mount it. This holds especially true when you are buying a split AC or a Window AC. These Air Conditioners need to be of the right size for them to be attached to your room. They should also be in proportion to the size of your room else you might end up getting an environment that either isn’t effectively cooled or is over-cooled. Furthermore, the AC might not fit properly and there’s a risk it might fall as well if it isn’t the right size.
  • Brand: Despite what many people out there might tell you, the brand matters a lot, because the brand determines how good an after-sales support would you be getting from the company, as well as how much money the product would fetch you if you were to resell it after a few months of use.
  • Other FunctionsYou must also check for other functions of the same product, i.e. what all it has to offer to you. In case of air conditioners, most of the double up as an air purifier and a dehumidifier – see if the AC that you have chosen offers all that.

Frequently Asked Questions (FAQs) About Air Conditioners for Grow Tents

Here is a closer look at some of the most frequently asked questions about air conditioners for grow tents and grow rooms that you need to know:

1. What are the different types of air conditioners for growers?

Broadly speaking, there are 4 different kinds of ACs for growers. 

  • Portable Air Conditioners: These are the small-sized air conditioners which you can move around with ease. These usually have wheels on the bottom and tend to cover a smaller area compared to the other kinds of air conditioners. However, these are considered to be the best air conditioners for grow tents and are great for growers who have a lesser number of plants and a smaller growing area.
  • Window Air Conditioners: These are age-old devices which you might have seen in some older buildings. A number of growers continue using these because of two reasons – first off, they are cost-effective and cost almost half (and even a third in some cases) of what a regular wall-mounted split AC would cost. Secondly, they are easier to install as they can just fit right into your window. They, however, are noisier and consume more electricity as well.
  • Split Air Conditioners: A split AC is one of the top options that growers have when it comes to choosing the best air conditioners for grow rooms. Split ACs consume less electricity and operate silently, and tend to cover a larger area as well. However, they are much more costly when compared to almost all other types of ACs and getting a good split AC might set you back by $700-$900 easily!
  • Ceiling Air Conditioners: Ceiling air conditioners are meant for extremely big growing areas such as if you are growing in a greenhouse or if you are growing across multiple rooms. These are piped ACs which hang from the ceiling. They are rather complex to set up and most growers who grow in grow rooms or grow tents would rather avoid them. 

2. How to decide the size of the air conditioner?

Two things come into picture here: The size of your grow room or your grow tent, which is the primary concern, and secondarily, the number of sources of heat that you have in your room. Calculate the heat generated by the heat sources in your room (BTU per hour) and then see if the AC that you are planning on buying has that kind of a BTU per hour cooling capacity to offer to you.

3. How long should the air conditioner be on for?

Ideally, we believe that the best air conditioners for grow tents and grow rooms should be left on all the time that the sources of heat are on. This is because they help counter the level of heat and a temperature equilibrium is maintained. However, different growers have different techniques of growing their marijuana and they may want the temperatures cooler or hotter based on their specific needs. However, make sure you do not turn it on for so little a time that heat actually becomes a problem or you turn it on for so long that the plants start to feel the effect of this cold weather which slows down their growth.

  1. Portable air conditioners: you need to avoid single hose or drain outlet types. Get dual hose or you will have horrible negative air pressure as the single hose intake is on the INSIDE of the grow tent. If you planned to exhaust your ceiling air you may collapse your tent with single hose air conditioners.
