"I've got an indoor grow light, how to choose the right grow tent size?" If you intend to buy a grow tent, then this question would have been in your mind. Every buyer thinks about the right grow tent size for the grow area.

Undoubtedly, you should get a whole idea and then buy the right tent according to your needs. In this article, we will help in buying the right grow tent.

If you are a beginner and confused about how to select the ideal grow tent size, you are in the right place. By the end of the article, you will be able to select the best grow tent for your grow area.

Let’s begin.

Why Calculate the Grow Tent Size?

Calculating or estimating the size of the grow tent is quite crucial because it is a one-time investment you are going to make.

Once you buy the tent, you use it for several years and then upgrade to a new one. Therefore, it is better to calculate the size of the grow tent in advance so that you can have a perfect grow tent for your grow area.

You need to select a suitable grow tent for your plants. There should be enough space to fit the plants you plan to grow inside. Moreover, you also need to consider the space you have for the tent.

It is a good idea to calculate the grow tent size before buying one. It helps you in selecting the right grow tent size according to the type of plants, grow area, size of LED grow lights, grow tent accessories, and many other factors.

If you don’t consider all factors and select the right grow tent size, you will face various issues, such as not having enough space inside the tent or an oversized tent according to the area you have.

Therefore, getting the right grow tent size is of utmost importance. Now, let’s dive into the factors you need to consider while selecting a grow tent.

Factors to Consider While Selecting a Grow Tent

Size of the Area

The first thing you need to consider is the space where you will place your tent.

You must have a dedicated space. Wherever you plan to place the tent, such as the basement or a spare room, take the dimensions of the space to get a clear idea.

If you have the correct dimensions of the area where you will place the tent, you know the limits while selecting a grow tent.

Your tent won’t be too large for the area, and it won’t be too short for the plants. You will get the perfect grow tent size if you calculate and measure the dimensions of the area.

Type of the Plant

Plants need a certain space to grow. At the final stage, they take considerable grow space.

While selecting a grow tent, you also need to decide the type of plant you will grow inside the tent.

Once you have decided the type of plant, you can check its optimal growth size. It will give you a better idea of the space that a plant will need.

Number of Plants

The grow tent has a limited space to grow a certain number of plants in the area. Thus, you need to decide the number of plants you want to grow inside the tent.

Once you have the idea of the number of plants you want to grow, you can select a suitable grow tent size for the purpose.

Usually, grow tent manufacturers mention the number of plants that can fit inside the tent, but you also need to consider the type of the plant because all plants have a different size at the final stage.

Grow Tent Accessories

Grow tent accessories will be inside the tent. So, they also take some space. The first thing that you need to consider is the grow lights. You need grow lights to mimic the sunlight inside the tent.

Grow lights take much space, and they also need a suitable clearance from the plants. If there is no clearance, the plants will burn.

There are different types of grow lights available on the market, and all of them have different criteria for clearance. They produce different amounts of heat; some are pretty hot while some are less.

For grow tents, LED grow lights are preferred. These grow lights are quite efficient, and they give off a small amount of heat. This quality makes them the best fit for grow tents.

LED grow lights are now commercially used, and they are preferred over incandescent bulbs, fluorescent lights, and HIDs.

The first reason to prefer these lights is the efficiency. Apart from that, there are tons of advantages to using LED grow lights.

LED grow lights have a longer life span; they can work for 15-20 years or even more. They also save your energy and reduce the electricity bills.

In addition, you have brightness control, spectrum control, and time controller. All these advanced features ensure the optimal growth of plants and high yield.

LED lights can also be easily adjusted in a grow tent, and you can also reduce their brightness if they have a controller. These features allow you to hang the lights at a suitable distance.

Thus, you can use them in the grow tents. Even if the height of the tent is low, you can use these and reduce the brightness.

Other than grow lights, you need to leave space for intake fans, exhaust fans, carbon filters, and a few other things.

Usually, these accessories are not a big problem because the tents have space for fans and filters. You can buy compatible fans according to the tent.

The main problem is created by the grow light, so you need to take care of that.

Another problematic thing is the temperature and humidity control. If the temperature and humidity are not in control, you might need a humidifier, dehumidifier, or air conditioning system.

Dimensions

The dimensions of the grow tents are always mentioned in the online stores. You can check those dimensions. It gives you a clear idea of whether you can use the tent in your grow area or not.

Pay attention to the height of the tent as well. Beginners usually consider the length and width, and they do not look for the height. Some sellers also hide the height to trick customers.

Make sure to check the height is enough for your plants and LED grow lights; otherwise, the tent will be of no use, or you might have to look for solutions to a new problem.

Budget

The last factor is the budget. This is the apparent factor because you need to remain under the budget while buying a grow tent.

Make sure to keep all accessories and tools in mind when you decide on your complete budget. You need dozens of things for growing plants indoors. Some of them are:

  • Water bucket
  • Hose
  • Pruners
  • Hygrometer
  • Timer
  • Gloves
  • Pots
  • Grow lights
  • Drainage system
  • Fans
  • Carbon filter

Grow Tent Buying Tips

Vertical Height

While deciding a suitable grow tent size for your area, you also need to consider the height. You should have an idea of the height you need inside the tent.

Moreover, you also need to check the height of the tent while buying it.

You need to consider the height of the pots and the distance at which you will hang the light. There should be a minimum clearance of 2’. Common LED grow lights do not have brightness control. So, you need to ensure the height; otherwise, your plants will suffer.

The height of the tent should be at least 2 meters. It is better to avoid the tent if the height is less than 2 meters.

Check the Weight Limits

You will be hanging lights inside the tent, and there will be other accessories, such as ducts and fans. Therefore, you need to check the weight limit of the tent.

The weight limit of grow tents depends on the type of piping used to create the frame. Some grow tents have a very low weight capacity, so they cannot handle the considerable weight.

Before buying the right grow tent size, you also need to check the weight limit to ensure you can hang the equipment you wish to.

Chambers

If you need separate chambers for the flower and vegetable stage, you can choose a tent that already has chambers in it. Many growers prefer chambers for convenience.

However, it is recommended to have separate tents for vegging and flowering.

Ducting Ports

There should be enough space to place ducting. In grow tents, there are intake and exhaust ports. You can use them and connect the ducting. Check the size of the ports so that you can have an idea of what kind of duct you will be using and whether it is according to your ventilation plan or not.
