How to Choose the Best Small Grow Tent

While size matters most when you’re scaling down your grow tent, there are other aspects to consider, too. From the layout and shape to the material type, here’s how to choose the best small grow tent for your needs.

Select the Right Tent Footprint

Depending on your property, you might have plenty of room for a small grow tent. Or, you might be trying to fit a small tent in a narrow spot. Fortunately, you have options, even with tents equaling around 16 square feet.

Some grow tents have a square base, while others are rectangular. Decide what footprint will work best for your layout.

Material Types and Colors

Grow tents come in different material types. Common options include canvas, oxford cloth, and PEVA. Most are dark in color to keep heat better, but you can also find color variations if you prefer.

Windows often use mesh material, so you can open them for ventilation as necessary. Consider whether you want a specific material type, whether for affordability or durability.

Tents With Access Windows and Wide Doors

Access is important for tending to your plants. From half-moon shaped doors to windows that roll up, most grow tents have multiple access points.

Think about how often you need to check on your grow and which way is easiest to get in. If you’re growing indoors, consider whether your tent will be up against a wall or multiple walls. This will determine what door or window arrangement will work best.

Advantages of a Small Grow Tent

A small grow tent can be beneficial to your growing process since they retain heat better than larger tents. Less air circulates in a smaller tent, so your plants get the warmth they need to thrive.

You can also put a small grow tent in places that larger tents could never go. Plus, if you can’t grow outside, you can still get optimal growing conditions with a small indoor tent.

Of course, you still need to manage the temperature and climate of your tent carefully. For common growing challenges—and guidelines—check out the YouTube video below.

What’s the Best Way to Use a Small Grow Tent?

Most growers opt to use a small tent indoors. They’re portable, don’t take up much space, and allow you to create the perfect environment for growing. And there’s no denying that a 2×2 grow tent fits well in small spaces.

You can also use multiple smaller tents to separate your grows. It might make sense to stagger your planting, for example, and house the younger plants separately from mature ones.

I like to separate the mature plants since the younger ones favor higher humidity. That way, the mature plants get the drier environment they need to thrive.

Of course, you can also adjust the temperatures separately for each growing phase.

Features to Look for in a Small Grow Tent

It can be tough to find the right small grow tent to suit your needs. But there are a few features that are usually winners in my book—here’s what to look for when shopping for a small tent.

All-In-One Tent Kits

If you’re just starting out, an all-in-one kit might be ideal. The best small grow tent might come with a kit alongside the tent, grow lights, a growing tray, and even tools. When you’re starting out or not sure what you might need, a kit can help round out your supplies—and they can be affordable, too.

Mylar Reflective Interiors

Most small grow tent setups use a reflective material in the interior. While you could use a tent without mylar or another shiny, waterproof barrier, the best small grow tent will be expected to have it.

Mylar is waterproof and reflects light back on your plants so you don’t lose energy. The watertight shell also helps protect your home—which is helpful if you’re living in a rental or have roommates.

Easy-Access Doors

Access is crucial for checking on your grow. But ducking over or reaching in a small window isn’t the easiest way to get in.

To tend to your plants, you need a door that swings wide open. Most grow tents use D-shaped doors with strong zippers to hold them shut. Opening and closing the door should be easy—and the zipper shouldn’t stick.

Ventilation Windows

Depending on where—and how—you set up your grow tent, the ventilation flaps might be crucial.

To grow cannabis the most effectively, you need an almost swampy growing tent environment. At the same time, you need to monitor the environment and humidity level. That’s where the ventilation windows come in.

If you have too much humidity, your plants could get bud rot or even slow down their growing. Window flaps that you can open and adjust give you an easy way to provide airflow—and avoid ruining your crop.

Grow Discretion

Although small, this tents are not really discreet. As there might be minimum light leakage, and let’s face it, they look like something going on in there.

If you happen to be looking for something stealthy, I have also reviewed the best grow cabinets for sale right now that will fit seamlessly with your other furniture and even hide the flowering odors.
