Growing a marijuana plant requires a lot of effort on the grower’s part. First-time growers often find growing weed to be quite a challenging task, but once they start getting into the groove, they realize it isn’t really that difficult a task. With time, growers realize that if they add certain extra elements to their grow room or their grow tent, they can get a better yield as well as care for their plants better. Portable air conditioners are one such device which will help ensure that the overall temperature of your grow room remains lower.
Over the course of this article, we shall be taking a closer look at why do you need an air conditioner inside a to grow room, what are the benefits of using an AC for the plants, as well as why grow rooms tend to heat up! We shall then take a detailed look at the product reviews for the four best portable air conditioners for grow rooms that you can buy off Amazon right now, followed by a look at the ‘buyers guide’ for those looking forward to buy an AC for their grow rooms.
Why Do Grow Rooms Heat Up?
Grow rooms tend to heat up primarily because of grow lights, which are the biggest source of heat (apart from a heater) over there. The use of grow lights is critical for growers because when you are growing your plants indoors, you need them to replace the natural light of the sun. However, lights tend to generate heat, especially if you are using lights such as High Pressure Sodium (HPS) grow lights or Metal Halides (MH) which are somewhat older compared to LED grow lights, which tend to be cooler.
However, even the LED grow lights do emit heat and they too need proper heat dispersion techniques. This heat that comes out of the grow lights causes the grow room to heat up, and the more the number of grow lights in the grow room the hotter the temperature will be! Another thing is that sometimes the outside temperatures also play a role and especially in summer months, when you add the warm temperatures to the heat that grow lights are generating, you will notice that grow rooms tend to heat up a lot! Hence, using a portable air conditioner is quite an important aspect for growers, especially those who live in warmer places.
The Need for Air Conditioners in a Grow Room
There is a strong need for portable air conditioners in a grow room because they help ensure the plants do not burn out due to this excess heat. While plants burning out is a major risk, another problem that you might face if you do not cool down your room is that your grow lights might stop working! If grow lights overheat, they might either stop working or sometimes even cause a fire hazard so it is essential for growers to make sure that their grow lights are being cooled properly as well. In the next section we shall be taking a look at some of the best portable air conditioners for grow rooms which will help you tackle all these problems with ease.
