How To Add AC To Grow Tent?

Grow tents are typically made of reflective canvas, so installing the AC unit on their walls is not practical. However, the tents have ports and openings through which cables and hoses can pass. These ports make installing lights and ventilation in the grow tent easy.

Permanent or window AC units are impractical for grow tents, so you must use portable ones. To install a portable AC in a grow tent:

  • Move it into the tent. Most portable AC units are lightweight and have wheels that help move them easily.
  • If your AC has a dehumidifier function, it’s wise to place it near an exit to make it easy to remove the excess water.
  • Locate the ports of the tent.
  • Fit the exhaust hose of the AC through the appropriate port.
  • Finally, pass the electric cord through another port and plug in the AC.

Air Conditioner Buying Guide

Though there are several great AC options, not all will suit your needs. Here are a few factors to consider before buying a conditioner for your grow tent.

Power consumption

Power consumption is one of the most important factors when buying an air conditioner. A suitable air conditioner for your grow tent must fit within your budget for the electric bill. Hence, you must check how much power the AC consumes before buying it.

In general, power consumption depends on the size. Small ACs require less electricity, while larger ones require more power. Consumption also depends on where the AC is positioned. ACs placed near windows need more power than ones placed anywhere else.


Although the brand of your conditioner doesn’t affect its function too much, it is still important to note. Some brands provide after-sale services like repair and services that benefit you as a buyer. In the same vein, some brands of ACs have higher resell value than others.

Cooling power

Cooling power is the power of an AC, which signifies its ability to remove heat from a room. Heat is typically measured in British Thermal Units (BTU). Before selecting a conditioner, determine how many BTUs of heat are produced in your grow tent.

An ideal grow tent AC should be able to remove as much heat per hour as the tent produces. Remember that the bigger your grow tent is, the more cooling capacity your conditioner needs.


The size of the AC you choose depends on your grow tent’s size. It’s vital to ensure that the AC you select fits inside the tent and doesn’t reduce the area available for your plants by much.

The chosen AC needs to fit inside the grow tent perfectly. A disproportionate conditioner is undesirable because it will either over-cool the tent or under-cool it.

Auxiliary Functions

Apart from cooling, most AC units perform other functions like dehumidifying. Hence, when choosing an air conditioner, it’s prudent to see what other secondary functions it can perform apart from cooling.


Choosing and installing the right air conditioner for a grow tent is essential for the health of your plants. The buying guide above should help you pick the perfect AC for your grow room. The three ACs listed above are great options that meet the conditions of the buying guide.

If you don’t have the time to sift through various choices, the Black Decker portable AC is the best AC for grow tent. It’s easy to install, use, and clean has a remote control, and has 3-in-1 functionality. Since it can cool an area of about 250 square feet, it’s perfect for a grow tent.
