Choosing the Best Fans For Grow Rooms: The Ultimate Buying Guide
The market is full of different fans for grow rooms, each with distinct features and performance strength. That’s why it is important to equip yourself off with the right information before you go shopping for a fan. Thus, you will have to sift through various online reviews to find the right grow fan for you. To make your search a little easier, we have put together this buying guide to help you in your quest. Here are a few things you need to ponder:
What’s The Size of Your Grow Room?
The number one factor to look into is the size of the grow room. This is to ensure that the fan has the ability to ensure optimal air circulation in the room. If that’s not attained, then you may not get the results you desire. To know how big your room is, multiply the length by the width by the height. Usually, the height is assumed to be approximately 1.25 meters. The answer you get will tell you the volume of air you need to remove from the room. For a small room, just about any fan will do the job. However, if the room is too big, then you may need a high capacity fan or several of them.
How Much Heat Do Your Lights Emit?
The lights in your room do not just emit light. In fact, before lighting up, it has to produce some heat. However, different electric lights produce varying levels of heat, which must be removed from the room by a fan. So, determine the kind of lights you have in your room. Then buy a fan with the ability to remove the heat being produced in the room. For instance, HID lights tend to heat up the room faster than fluorescent ones. That’s why you need a zealous fan that can remove the heat in no time.
What’s The Diameter of the Fan?
Just like any other product, fans exist in different sizes. In this case, size is determined by the diameter of the fan. So, the diameter is an important factor when it comes to choosing the best fans to grow rooms. You will have to choose anything between 4 inches and 16 inches in diameter. However, a key consideration before buying a fan is the indoor set-up. In most cases, a 6-inch fan is large enough to fit in any grow room. If it doesn’t work, then buy a converter and not a new fan.
What Noise Levels Can You Tolerate?
Fans, no matter where they are used, often produce noise. So, there is no such thing as a quiet fan. However, you will be able to find a fan that’s quiet for your liking. The problem with quiet fans to grow rooms is that they are less powerful. If performance is the most important consideration for you, then the noise levels shouldn’t matter that much. Before you go out shopping for fans for your grow room, be ready to compromise on some things while striking a balance.
What Materials Is The Fan Made Of?
The best way to know if a fan is going to last long is to look at the material used to make it. While some are made of durable metallic parts, others are nothing but plastic. Of course, the less durable a fan is, the less expensive it is. If you are uncompromising on quality, then be ready to pay more. The best fans for grow rooms are those which have UL-listed components. With that, you can be sure that the components of the fan are certified to be durable and effective. Why should replace a fan after a short time when you can have a durable one from the get-go?
How much are you willing to spend?
When all is said and done, the price is what will determine whether you walk away from the shop with a fan or not. So, have your budget at the back of your mind. Sift through the stores and compare the prices of different fans for grow rooms. If you find a quality fan within your price range, why don’t you go for it?
You see? Finding the best fans for grow rooms doesn’t have to be that difficult. Provided you understand the size of your grow room, the amount of heat that your lights emit, the diameter of the fan, as well as your budget, there’s no reason you shouldn’t get a great fit. We hope that our choices will inspire you to become a pro in growing weed and other herbs.
