10 Best Stealth Grow Box Systems For Your Flowers in 2021


With the legalisation and rapid rise of legal forms of cannabis all around the world, grow cabinets or grow boxes are now a heavily sought after product.

When we say legalised cannabis we are not talking about marijuana we are talking about hemp. Although these grow boxes can also grow marijuana however this is illegal in most countries around the world.

In general, people think about hemp if you say legal cannabis. CBD oil is derived from the cannabis strain hemp. Here, we will advise you on the best ways to grow hemp at home. Stealth grow boxes or grow cabinets using hydroponic systems are the ones you use when growing hemp at home.

What is a Stealth Grow Box?

A stealth grow box is a unit for growing plants in your own home. They are made to be discreet and fit in within the décor of your home while the plant grows safely inside. This box functions using light, and water enriched with nutrients to supply the plant with all the essentials for growth.

Stealth grow boxes are ideal for anyone looking for a place to grow herbs or other plants for personal use at home without needing space outside or a greenhouse. This is a self-contained unit for optimum plant growth using LED lighting and nutrients to guarantee quality grow conditions.

We will look at some of the best stealth grow boxes & cabinets available on the market right now.


Let me say this, legalisation of cannabis doesn’t carry the same set of rules and regulations in all countries. In some cases including most of Europe, a license is required to grow hemp in your home.

When Using a Stealth Grow Box what is the Smell like?

Most quality brands of grow boxes come with installed carbon filters as part of the unit. This ensures that any smell or odour coming from your plant or herb is contained and filtered before leaving the grow box.

When choosing a stealth grow box for your home it is best to research and choose one which comes with such a feature. Thankfully we have put together a comprehensive list of grow systems for you here and highlighted those which come with filters for odour prevention.

How to Set up a Stealth Grow Box

So, you have ordered your stealth grow box, received your delivery and now wondering where to begin? Here are some steps to consider when setting up your grow box:

  • Find a space in your home where your grow box can sit undisturbed amongst your furniture.
  • Clean the area before setting up your grow box to ensure no dust or germs get onto the grow box system while you set it up.
  • Follow the instructions that come with your grow box carefully. Check each step is completed correctly before moving onto the next.
  • Monitor your plants as required to check watering, lighting and other areas are all working as they should.
  • Now, watch your plants grow!

How Tall Should a Stealth Grow Box be?

The height of your grow box will depend on what type of plant you wish to grow in it and how many. Some plants grow taller than others and so need more space to mature. Decide on your herbs / plants first before making any purchases.

A small sized grow box is around 24” high, some may be a little less. A medium height option would be 36” to 48” high. Lastly a very tall option of grow box can be anywhere from 60” to 80” in height. It depends on the brand of box too of course but this should give you a general idea.

If you are stuck for space in terms of height do some research on your chosen plant and see if short varieties are available to lessen the need for space on top. Make sure to measure out the area at home you plan to place your grow box before purchasing one so that when your unit arrives it suits the size of your space whether big or small.

As grow boxes increase in popularity so do the varieties in design. So, whether you live  in an apartment or a house you will find the best option for your home.

The Benefits of Using Indoor Grow Boxes

As opposing to growing herbs on soil, hydroponic farming uses just a fluid mixture of nutrients and water. Hydroponic farming and hydroponic systems revolutionised the way we grew herbs. Here are some benefits of indoor grow boxes;


Highly convenient, and that’s something all of us would prefer over awful farming on the soil. Building a hydroponic system requires a lot of expertise, time, space, and dedication.

Trust me; you do not want to build a hydroponic system from scratch. Hydroponic grow boxes are plug and play, and that’s why people prefer them the most.

Faster growth

Comparably, hydroponic grow boxes offer more rapid growth by transferring the nutrients swiftly. Hydroponic systems provide light and water directly to the roots and herbs. As a consequence, the herbs absorb the nutrients quickly and grow faster than traditional soil-farming.

No-soil Farming

Hydroponic systems don’t use soil to grow plants. “No soil” farming means no bug infestations, fungus or diseases. Soil is the primary route for the funguses and plant-eating bugs to reach the herbs.

While growing the herbs using only water, you can avoid all these unnecessary woes.


Hydroponic grow boxes reuse the water, and it brings down the water wastage, which is not the case in regular gardening. Water re-usage means the overall expense on maintenance becomes less. Likewise, hydroponic grow boxes conserve the human effort during the entire farming process.

The Difference Between a Grow Box & Grow Tent

The practice of indoor gardening is gaining wide acceptance each passing day as more people feel a need to grow one plant or the other. However, a lot of folks are still confused about the best indoor growing apparatus to use, grow tent or grow box.

Both are similar in function and features, but they are not the same. Below, we help you outline the major differences between a grow tent and a grow box. This will help you know which works best for you.

Grow Tent Capacity

Grow tents have more space to plant your crops when compared to the grow box. That is to say, with Grow tents you are guaranteed to plant more crops and get more output.

Experienced gardeners go for Grow tents over Grow boxes because of this simple difference.

Ease of Movement

Grow tents are designed in such a way that it is easy to dismantle it and couple it back. This makes it very user-friendly when compared to the Grow box because it can easily be moved from one place to another.

Even though it is not advisable, but a situation arises that demands that you change the location of your indoor garden.


One of the characteristics of great product design is maintainability. The people that designed the Grow tent made it maintainable. This is one feature that makes the Grow tent stand out from the grow box.

In the event that you need to upgrade any of the parts, or replace broken components, you can easily do that without waiting for a professional


Unlike the Grow Box, the Grow tent is intentionally designed in such a way that you can access any part of the tent without disturbing the crops. This is because a big Grow tent has many access points that enable you to reach the back of the container.

Grow Boxes Have Greater Durability

On the other hand, because of the portability of Grow tents, it is prone to wear and tear especially if you bought a cheap one. Grow boxes are stronger and durable.

So, if you are looking for something that will serve you longer, then you might consider getting a Grow box.


Well, some people care so much about the look of a device especially if it’s one that will be placed inside their home. If your indoor garden is somewhere that is visible to all, then you might consider getting something that is appealing to the eyes.

This is something that the Grow box offers better than the Grow tent. The Grow box is designed to look like a cabinet that can easily blend in as one of the home furniture.
