Best Big Grow Tents

Grow tents are very important when it comes to growing marijuana indoors. Not just growing weed, but even while growing any plant, you need to ensure that you are getting a good quality grow tent. The primary function of a grow tent is to ensure that the efficiency of a grow light is used to its maximum possible extent, giving you higher yields and a good growing experience. Over the course of this article, we shall be taking a closer look at grow tents – what they are and why they are important, but more specifically, we shall be focusing on big grow tents (around 10 ft x 10 ft in size).

While small-scale growers can choose a number of options, those who are growing in bulk need large growing spaces and a big grow tent would be great for them. In this article we shall be taking a closer look at the 4 best big grow tents that you can buy off the internet right now to start off with growing marijuana indoors. Big grow tents allow large-scale growers to grow their plants with ease and have a lot of the plants kept under one single unit, making it easier for them to manage as well. 

What Are Grow Tents? Why are They Important?

Grow tents are basically a tent inside which you can grow your marijuana plant. However, these are not ordinary tents – these tents are lined with reflective layers on the inside and come with space to fit equipment that can provide essential elements needed for the plants to grow such as grow lights for light, inline fans for air and carbon filters to ensure that the smell remains contained. Grow tents are great for plants because when compared to an entire grow room, these are smaller, limited areas which makes it easier for growers to create an ideal condition for growth. This gives them a better control over their plants and also allows for higher yields. 

Grow tents also provide your plants with a protective covering which ensures that pests and insects do not affect your plants and that they can grow without facing much of a problem. Moreover, using a grow tent also ensures that growers can actually conceal their plants because while marijuana has been legalized across many parts of the US as well as the world, people continue to look down upon it and it still remains a social taboo. Hence, growing weed in a grow tent ensures it remains hidden from guests/visitors. Using a good quality carbon filter will also ensure that the smell doesn’t leak out, keeping your weed plants a complete secret.

Sometimes you also need to get a grow tent based on your plant’s needs. Plants in different cycles of their growth period need different kinds of lighting which needs to be hung from a different length. Hence, grow tents can help you differentiate your plants based on their growth phase as well. They are also useful for growers who are growing multiple strains of weed so that they can be grown separately and can be cared for.. 

Importance of Big Grow Tents

Looking specifically at big grow tents now, the idea here is that these will be great for growers who tend to grow large batches of marijuana. While small-scale growers who are growing just a couple of pots don’t need to worry much because they can get hold of small-sized grow tents (2’ x 2’ or 4’ x 4’), it is the large-scale growers who need to get hold of these big grow tents (10’ x 10’ and above) as these tents will ensure that growers are getting the most out of their plants. 

Often, big grow tents are also bought by growers who operate on a very large scale with every grow tent having a different strain of marijuana growing in it – these setups often involve the use of multiple big grow tents. Hence these large-sized grow tents are pretty important for growers. Let us now deep-dive into some of the best big grow tents for growing marijuana indoors that growers can buy off Amazon right now!

What to Look For in a Grow Tent?

Now that you know which the best big grow tents are, let us also take a closer look at what are some factors that you need to consider before you make a final decision about buying these grow tents: 

  • Size: The size of your grow tent is really important. You need to know exactly how big a grow tent you need because having a small grow tent would mean that some of your plants will get left out and having a bigger grow tent would mean some light would be in excess. Hence, you need to know just the perfect length, width and height. Height is also important because plants tend to grow upto great heights and you need a proper grow tent which allows them to grow to their fullest potential. 
  • Ability to Contain Light: The material using which the grow tent has been made needs to be considered before you buy it. 600D Oxford Polyester Cloth is the most commonly used fabric and it is a good option too. However, there are some grow tents which go for inferior quality cloths which often end up in light leaks. Make sure you are getting a double-stitched and tear-proof cloth. Also look for pinhole leaks around vents for inline fans and for leaks that might happen around zippers.
  • Durability: Check how sturdy the poles around which the tent rests are. You need durable poles made of metal in order to ensure two things: firstly, that the tent remains sturdy and stable, and secondly, that you are able to hang grow lights and carbon filters and other grow tent accessories on to it without worrying that it might collapse. For a standard understanding of things, you must know that an average 4×4 grow tent can usually hold about 110lbs of weight and a 10×10 grow tent should ideally be able to hold upto 220lbs.
  • Zipper Strength: Now this might sound silly but this is a primary concern for many buyers! Many growers have faced the agony of having a broken zipper or a malfunctioning zipper which takes quite an effort to be fixed! Having a heavy-duty industrial quality zipper is always beneficial and in 2020 most grow tents are taking care of this need. However, while looking forward to buying the best big grow tents for growing marijuana indoors, you must always check the user reviews for zipper quality!
  • Observation Window: This is another essential feature which is now a part of most grow tents. Instead of opening up the whole damn thing and unzipping the grow tent and having light leak out, you can simply open up the observation window and take a quick look at how your plants are doing. Not all grow tents have these and make sure the ones that you are buying come with such windows built on them.
