How Do You Choose a Grow Tent?

In all my years of growing cannabis, one of the most popular questions is how do you choose a grow tent?

It’s no wonder why this question is so popular. Grow tents cost money, come in different sizes and shapes, are made of different materials, and there are dozens of brands with hundreds of options to choose from, making the decision process an absolute nightmare.

So, we’ll skip the formalities and head straight into the meat and potatoes of how you should choose an indoor grow tent.

Here are the four most important factors:

  • How many cannabis plants do you want to grow?
  • How much space are you working with?
  • What is your budget?
  • What type of features do you need in the tent?

We’ll discuss each factor further in detail in the next section. Remember, your needs will likely differ from another cannabis cultivator, which is why you need to consider these personal questions when selecting the best possible grow tent.

Choosing an Indoor Grow Tent Based on Plant Count

If you’re like me, the first thought that comes into your mind is, how many weed plants can I fit in here?

Although it’s normal to want to stuff your grow tent full of gorgeous green weed plants, there’s a rule of thumb to abide by. Remember, these are general guidelines and are only meant to make the decision process easier for you.

Below, I’ve provided a table that contains specific grow tent sizes with their corresponding plant count.

Grow Tent Size Ideal Plant Count
2′ x 2′ 1-2
2′ x 4′ 2-4
3′ x 3′ 3-5
4′ x 4′ 4-6
4′ x 8′ 5-12
5′ x 5′ 4-10
5′ x 10′ 9-16
8′ x 8′ 9-16
10′ x 10′ 10-20

Although this table isn’t the be-all and end-all — it gives you a quick rundown on how many marijuana plants you can fit in a grow tent without overdoing it.

As a final tip to consider, I believe that sizing up when buying a grow tent is a practical method to future-proof your indoor garden. You’ll be surprised by how fun growing weed is — especially come harvest day.

Unless you’re absolutely limited on space, why should you limit yourself to one or two cannabis plants? The bottom line is to size up your tent to ensure years of fruitful harvests of homegrown weed.

Choosing a Cannabis Grow Tent Based on Available Space

From spare bedrooms to walk-in closets and everything in between, you need to break out the measuring tape before you buy a grow tent to make sure it’ll fit.

If you fail to do this, you may buy a grow tent that is too large or too small. Sometimes, the measurements are a bit tricky, so I’ve compiled a table below that converts grow tent sizes into feet, inches, and centimeters.

Grow Tent Size
Feet Inches Centimeters
2′ x 2′ 24″ x 24″ 61 x 61
2′ x 4′ 24″ x 48″ 61 x 122
4′ x 4′ 48″ x 48″ 122 x 122
4′ x 8′ 48″ x 96″ 122 x 244
5′ x 5′ 60″ x 60″ 153 x 153
5′ x 10′ 60″ x 120″ 153 x 305
8′ x 8′ 96″ x 96″ 244 x 244
10′ x 10′ 120″ x 120″ 305 x 305

Remember, most grow tent manufacturers size their products in feet or inches. However, it’s always helpful to have the centimeter conversion just in case.

Once you’ve measured the area where you’d like to set up your indoor grow tent, you’ll have a very clear idea of which size to purchase.

Choosing a Cannabis Grow Tent Based on Available Budget

Ah, the woes of money.

If we all had access to unlimited cash, we could buy top-of-the-line grow tents without a moment of regret. Instead, most of us, including myself, have a set budget that we can allocate towards a grow tent.

Grow tents maintain a wide price range, such as $80 to well over $1,000. Therefore, your budget plays a key role in which grow tent you decide to buy.

Remember, you do not need the most expensive grow tent to yield top-shelf weed. At the same time, you do not want to buy the absolute cheapest tent on the market that can leach harmful chemicals onto your weed crop.

As you can see, you need to find a tent that’s within your budget and provides exceptional quality control. The last thing you want to happen during the middle of the flowering stage is the stitching to come undone and allow a light leak to occur.

Luckily for you, I gathered and reviewed many different grow tents that will satisfy all budget types below.

Choosing an Indoor Grow Tent Based on Features and Accessories

The grow tent is the main body of the indoor cannabis garden.

Without the body, you don’t have space for your cannabis plants, grow lights, ventilation system, and other essential pieces of equipment. Therefore, you need to select a grow tent that comes equipped with the necessary features and accessories to sync your growing equipment seamlessly.

Here is a list of excellent features that you will discover throughout our recommended list of grow tents:

  • Ducting ports
  • Cable ports
  • Height-adjusted roof
  • Industrial strength zippers
  • IR blocking roof
  • Heavy-duty canvas thickness
  • Reflective mylar
  • Non-corrosive metal poles
  • Mesh viewing window
  • Removable tray or spill tray
  • Rear access door
  • Waterproof

Each of these features makes it easier to grow top-shelf weed.

For example, a grow tent with heavy-duty metal poles will not rust over time or collapse under heavy load. Remember, some of the most basic features are often overlooked by new cannabis cultivators, such as I experienced many years ago.

From rapid clean-up (spill tray) to convenient access (rear door), a grow tent’s features are the key to success.

Although it’s great to learn by trial and error, I want you to make the right choice on the first go-round. Therefore, you need to read our grow tent reviews to get up-to-date information.

Considering Your Indoor Grow Tent Options

As you can see — there is a lot to consider when buying a grow tent for cultivating marijuana.

However, my goal is not to overwhelm you. Instead, my objective is to make your decision process much easier. Therefore, if you want a plug-and-play experience, you may want to consider a grow tent kit that offers a tent with all the necessary pieces of growing equipment in a single package.

However, if you’d rather have complete control of every aspect of your grow tent and growing equipment, continue reading below for my full list of indoor grow tent recommendations.

The heavy-duty stitching prevented significant light leaks and even reduced the aroma of the weed growing within. From the zipper to the observation window, everything worked swimmingly.

When I first read about 2-in-1 grow tents — I thought it was a gimmick.

After using a ViparSpectra 2-in-1 grow tent — boy was I wrong! Before using the ViparSpectra 2-in-1 grow tent, I always germinated cannabis seeds in a separate space.

Having the convenience of a siloed space for my weed seedlings was a game-changer. Suddenly, I could germinate marijuana seeds (and veg juveniles!) while my primary crop was vegetating or flowering.

After spending months (and growing pounds of top-shelf weed) with this professional-grade grow tent, here’s what I liked and didn’t like:

Pros:
● Roomy design that’s feature-rich and ready to handle heavy-yielding crops and weighty grow equipment
● Ultra-thick 1680D canvas that feels bulletproof
● Quality control is on point and reduces instances of light leaks and stitching errors*

Everything You Need to Know About Grow Tents

Now that you’ve gone over each of our most highly recommended grow tents for indoor cannabis cultivation — it’s time to learn what grow tents are and how they function.

What is an Indoor Grow Tent?

An indoor grow tent is an enclosed space that allows you to create the perfect growing environment for marijuana plants.

The tent itself is composed of various materials, sizes, and features. However, the overarching point is to optimize the environment for maximized yields of weed.

Although we speak about the importance of it — the significance of the equipment used within the grow tent is of equal value.

Think of the grow tent as the atmosphere and the growing equipment (grow lights, ventilation, irrigation system) as the planet. Without the atmosphere, the earth could not support life — let alone cannabis plants.

Why Do You Need a Grow Tent to Cultivate Weed Indoors?

Marijuana grow tents are used for a number of beneficial reasons. Here is a list of why you may want to use one for your upcoming indoor cannabis crop:

  • Discrete
  • Protection
  • Controllable environment
  • Year-round growing
  • Simplicity
  • Energy Efficient

Now, let’s briefly discuss each so you can better understand why it’s recommended to use grow tents for indoor marijuana cultivation.

Discrete

As you power up your 1,000-watt HID — you’ll suddenly realize that your apartment looks like it’s about to blast off to outer space.

Without a grow tent to contain the light, your room will be flooded with uncontrollable lumens. Grow tents contain light within their four walls, thus achieving discretion.

Additionally, grow tents reduce the spread of odor and noise. With the help of carbon filters, inline fans, and fan silencers, you won’t have to worry about your nosy neighbor.

Protection

One of the best benefits of using an indoor grow tent is for protection.

If you’ve grown weed outdoors, you know there’s a high probability of encountering wind, rain, and snow. Additionally, roaming pests and wildlife present a severe problem for outdoor marijuana growers.

Growing cannabis seeds and plants within a grow tent will protect your cannabis crop from the elements and more.

Controllable Environment

Grow tents allow you to grow cannabis under ideal conditions.

By using grow lights, fans, environmental controllers, irrigation equipment, and more, you can dial in the perfect environment for your weed crop. From optimized temperatures to honed in humidity, you’ll have the ability to ensure your cannabis crop receives the very best conditions.

Year-Round Growing

Outdoor cannabis cultivators are typically limited to a single harvest per year due to seasonal shifts.

Grow tents, on the other hand, allow year-round weed growing capability.

Through the use of grow lights, indoor growers can produce weed at any point in the year while using a marijuana grow tent. Overall, grow tents allow you to determine when you want to grow cannabis instead of relying on mother nature.

Simplicity

Grow tents are the best alternative to complicated grow room build-outs.

Converting a garage or spare bedroom into a customized grow room takes a lot of money, time, and effort. Alternatively, grow tents can be set up within minutes and do not require tools or complicated renovation.

Energy Efficient

Another notable benefit of grow tents is their energy efficiency.

Energy efficiency is achieved through a number of avenues, which we’ll list below. Remember, the greater the energy efficiency, the lower your overall electricity costs and carbon footprint.

  • Mylar’s reflective material enhances lumen output from grow lights
  • Grow tent design efficiently manages temperature fluctuations
  • Grow lights are on a timer

Now that you understand the significant benefits of indoor grow tents let’s look at other notable aspects that can affect your upcoming cannabis grow.

The Differences of Grow Tent Quality

Next, let’s talk about the differences in grow tent quality and how they may affect your upcoming grow.

With hundreds of different brands, it’s safe to say that not all grow tents are created equal. Below, we’ll discuss key elements that can make or break your cannabis crop.

Canvas Material

When it comes to the canvas (outer body) material of grow tents, there are two standard thickness ratings:

  • 600-Denier
  • 1680-Denier

Denier describes the thickness of individual threads. The greater the thickness, the increased likelihood of durability.

As you can imagine, you want a robust grow tent that can handle a room full of growing equipment and constant use. Therefore, understanding the difference in denier rating is crucial when choosing a top-of-the-line grow tent.

Overall, manufacturers use 1680D fabric when crafting a heavy-duty grow tent. On the other hand, grow tent makers may choose the lighter 600D fabric for smaller tents that aren’t meant to handle many marijuana plants.

In any case, high-denier fabrics will last much longer than low-denier fabrics. Additionally, a thicker denier is crucial in blocking light and preventing light leaks, which we’ll cover in the next section.

Light Leaks vs. Lightproof

As we mentioned in the previous section, canvas material (denier thickness) is the primary factor in determining the light proofness of a given grow tent.

Remember, light leaks are a grower’s worst nightmare. Cannabis plants are prone to hermaphroditism when exposed to light during the 12-hours off period.

Therefore, you must select a grow tent manufacturer that utilizes high-denier fabrics in conjunction with professional craftsmanship.

In general, the higher the denier count, the greater the chances are that your grow tent is lightproof. However, quality control is an essential factor in blocking disastrous light leaks.

From loose threads to messy stitch-jobs, a lack of quality control from a grow tent manufacturer can result in stressed-out marijuana plants. Although it’s virtually impossible to find a 100% light proof tent, our most recommended grow tents are close.

Mylar Quality

Mylar is the reflective material that’s placed on the inner portion of the tent.

Mylar is an excellent innovation because it reflects light all around the plant. As the grow lights send lumens to the canopy of the marijuana crop, the mylar reflects the light to the undergrowth.

Therefore, mylar plays two roles:

  1. Increase the overall brightness of grow lights
  2. Increase reflective potential to underside growth

However, not all grow tent manufacturers utilize high-quality mylar.

As you’ve seen in our reviews, we always tell you the type of mylar used. Whether it’s 99% reflective mylar or diamond-shaped, our reviews provide you with answers.

Lastly, low-quality mylar is known to leach poisonous lead, cadmium, or mercury on your weed crop — especially when high heat is introduced. Therefore, mylar quality is an important consideration when buying an indoor grow tent.

Plastic vs. Metal Support Poles

Grow tents are supported by a series of poles, which also bear the weight of various pieces of grow equipment.

Similar to the bones in your body, support poles keep the tent standing. Therefore, you need to understand the key differences between grow tents with plastic and metal poles.

When possible, you should always avoid grow tents equipped with plastic support poles. Remember, your grow tent contains grow lights, which can significantly increase the temperature.

Plastic can melt when exposed to high temperatures, making plastic support poles a terrible choice.

On the other hand, metal (steel) support poles do not rust nor melt when exposed to high heat or moisture. Additionally, metal support poles are less likely to break under pressure when holding up to 120-pounds of grow equipment.

There is, however, one downside of metal support poles. If the grow tent manufacturer does not provide adequate quality control, the welding points on the support poles may be weak.

If the welding point is weak, the support pole has a higher chance of snapping. Thankfully, we’ve covered the best grow tents that offer exceptional welding quality.

What Can Grow Tents be Used For?

Grow tents have many uses.

From growing cannabis to drying harvested buds, grow tents are a jack-of-all-trades for indoor cultivation. Below is a list of grow tent use cases that you can use to enhance your overall indoor marijuana garden.

  • Seedling/cloning room
  • Mother room
  • Vegetative room
  • Flowering room
  • Drying/curing room

Overall, grow tents can be transformed into anything that you want. With a little bit of creativity, you can transform a small grow tent into a seedling chamber.

Alternatively, a mid-sized grow tent can provide the optimal location for vegging your weed crop before it heads into the flowering chamber.

Lastly, you don’t need to have a grow tent for every occasion. Instead, you can go from seed to harvest in a single tent.
