Do you want to start growing cannabis indoors, but you don’t have enough space? No worries, indoor growing is possible with minimum effort and limited space. Get yourself a grow box and make your horticulture dreams come true.

The best grow box will ensure success in indoor gardening. This equipment makes an ideal growing environment for plants, since it’s not affected by external weather conditions. It means that you can grow anything you want regardless of what season of the year it is – winter, spring, summer, or fall.

However, there are lots of grow boxes available nowadays, so choosing the best one is crucial.

What is a grow box?

First, what is a grow box? To put it simply, a marijuana grow box is a contained ecosystem that’s designed to grow cannabis. It usually comes as a kit, meaning not just a cabinet by itself, but with almost everything that you’ll need to help your plants grow from seedlings to maturity.

A grow box can be used both in a hydroponic setup (where plants are grown in a nutrient solution) and soil (where plants get nutrients from the soil). Some grow boxes need a little work, while others are automated.

A grow box can help you grow different strains of cannabis, but you can also cultivate other crops, such as herbs and vegetables. You just have to adjust the temperature, humidity, and other conditions depending on the type of plant you are planning to grow.

How does a grow box work?

Before growing your weed in a grow box, you need to understand how it works. A grow box or grow cabinet provides an environment that has almost similar conditions to when you grow in a natural setting outdoors; however, you have more control of the light, humidity, temperature, and other factors, because everything is limited within a tiny box.

Since this equipment gives you overall control of your plant’s needs, you no longer need to check the weather updates to protect it from harsh weather conditions like rain or snow. Also, you won’t have to worry about bugs or diseases.

Furthermore, a grow box is effective in generating high-quality yields, and it helps you grow marijuana discreetly because it’s so compact. It won’t attract attention from your neighbors. A marijuana grow box is definitely a smart investment, even for someone new to growing cannabis.

Why should you use a marijuana grow box?

There are lots of advantages when using a grow box. Besides helping you to grow discreetly, it can perform other functions too.

As mentioned earlier, most marijuana grow boxes are equipped with everything to get you started. Though not as flashy as some of the best marijuana grow tents, a good grow cabinet usually comes with high-quality LED grow lights, filters, and fans for enhanced ventilation and air circulation. Also, it’s equipped with reflective interiors that can distribute light to every part of your plant.

Many grow boxes also have additional features. You could get that one with a timer, pumps, pH adjusters to correct poor soil pH, and more. It could also have a locking feature to protect your automated grow from pests.

Grow boxes are highly adaptable, meaning you can adjust everything, including lighting, ventilation, and humidity. Some even allow users to change the watering schedule. You can grow seedlings, mature plants, and even clones inside a weed cabinet.

Another reason you should use a marijuana grow box is it’s more discreet than a grow tent, since it looks like a normal cabinet or storage locker. It may also feature an odor-control system that can eliminate the scent of marijuana. You won’t have to worry about anyone wondering what you are growing.

Finally, these compact boxes aren’t that expensive compared to a standard grow tent. But keep in mind that a good grow box should come with all the components you need, including the grow lamps, filters, fans, etc. It’s best if you don’t have to buy these items separately because it will save you some time and money and reduce stress. In short, you should get the best value for your money with a grow box.

What are the things to consider when choosing the best grow box?

Before we proceed with our review of the best grow boxes, you should be aware of the different factors you should consider when buying one. Here are the things you should check first before making a purchase:

Size of the grow box

The first thing to look at is size. Measure the area where you’re going to place the grow unit. That way, you’ll know the exact size of grow box that can fit in your area. If you don’t get the correct size, you might end up with an expensive package that doesn’t fit. But if it’s too small, you will miss out on the opportunity to grow more plants.

Lightproof capability

Investing in a grow box that isn’t perfectly lightproof is a waste of money. If you wish to grow cannabis successfully indoors, you need to make sure that your grow box is lightproof. Just imagine what would happen if light leaks when your plants are in the flowering stage. You should check for yourself if light can penetrate the interior while the light is off before buying.


When you’re shopping for the best grow box, consider the accessories needed for complete installation. Luckily, most grow boxes are sold as complete packages, which is a huge advantage for consumers. Buying extra gear can increase the cost of installation. Compare brands, and choose the one that’s best for your budget and setup.

Adjustable features

Most growers want a comprehensive grow box that’s adjustable. Some gardeners use a grow box to keep the mothers for generating clones, while others use it for breeding new strains of marijuana or germinating seeds. You also want to make sure that the box can help you cycle your crop through different stages of growth.

Style and design

If you’re aiming for a discreet way of growing, choose a small grow box that can blend in with your furniture and room decor. You should also go for a lockable grow box for extra protection. Moreover, some units are fully automated and can be linked to a smartphone app.


The cost of the unit itself and the installation fees should also be considered. If you have a big budget and ample space, then buying a more expensive one that’s more durable is an excellent idea. However, you should think of a convenient size that’s more affordable if you’re just starting out.
