Stealth Grow Boxes

For many indoor growers stealth is of the utmost importance. A successful marijuana grow can give itself away in many ways. You need to conceal odors, light and noise. A stealth hydroponic grow box is the perfect solution.

Most grow boxes are designed with stealth in mind, but the actual degree of security varies from grow box to grow box. We’ve looked through all the options on the market and chosen the very stealthiest grow boxes for your next secret grow.

When choosing a grow box for stealth, there are several important considerations:



Does the grow box keep 100% of odors from leaking out?


Do any rays of light slip past the edges of the door?


Ever seen a steaming file cabinet? Me neither.


Again, humming and buzzing and fans rattling in your filing cabinets? Nope.


Color? Shape? Does it look natural in your home?


At the end of the day a grow box must fit your budget while still providing all the stealth features you need.

Of course, the grow box must also suit your needs. Consider the plant capacity and potential yields, whether it has single or dual chambers and whether it is set-up for a hydroponic or soil grow.

As we all know, the wonderfully pungent smell of ripe weed can be so strong that it is overpowering. Some seed strains like Skunk #1, Hindu Kush or Cheese are especially potent. Keeping these buds from giving away your grow takes serious odor control.

There are several ways stealth grow boxes combat odors, some more effectively than others:

  • Odor Absorbing Gels
    • Some of the cheaper grow boxes use odor controlling gels. They do work well in small spaces, but they are not potent enough for especially stinky strains or larger set-ups.
    • Gels are consumed over time and will need replacement. Don’t just follow the manufacturer’s guidelines. Be prepared to change them sooner if you start to notice any odor.
  • Carbon Filters
    • Carbon filtration is your best option for total piece of mind as far as odors are concerned. Carbon filtration works by passing the outflow of air from your growing space through activated carbon granules.Activated carbon is charcoal that has been chemically treated to give it a very open structure. The result is a highly porous substance that has an incredibly large surface area, making lots of spaces to trap the tiny odor molecules.
    • Choose a system with the largest granules possible by either weight or size. Larger granules = more powerful odor control
    • You will have to change the activated carbon in your filters from time to time.
    • Brand name carbon filters like are better than generic versions. Sad but true, where stealth is concerned the more expensive choice is often the most effective.


Strange lights coming from cabinets, attics and spare rooms or tents can also be a tell tale sign that there’s a bit of indoor gardening going on. It is important that the light stays inside the cabinet.

A good Grow Box will be completely light tight and have light baffles fitted to keep the light in. More on marijuana grow lights.



Whilst heat signatures can be a problem for big grow ops, small localized heat signatures are unlikely to cause too much trouble. However warm air will be vented from your grow box. If it is in a room where visitors go they might find it odd that your filing cabinet is generating heat.

Why do Grow Boxes Get Hot?

Your grow lights are the source of heat in a stealth grow box. HID lights in particular generate a lot of heat and can burn plants in the confined spaces of a grow box. For a stealth grow, choose CFL or LED lights:

CFL Grow Lights – Remain cool to the touch and make controlling heat in a grow box easy. They are not as effective as producing high yields as HID or Full-Spectrum LEDs.

LED Grow Lights – These are the Holy Grail of low heat cannabis lighting. They are much cooler than HID grow lights because they are more efficient. Save energy, keep the grow box cool and watch your plants thrive.

A good stealth grow box is lined with Mylar, a reflective paneling that returns errant light to the center of the grow box. This improves growth and insulates the grow box. Look for grow boxes with removable Mylar panels for easier cleaning.



There are two important financial factors to consider when purchasing a stealth grow box:

1. The Initial Cost

You should consider your goals when choosing a grow box. If you are an occasional grower, a cheaper grow box might be a reasonable option. But if you plan to use the grow box continuously, and stealth is essential to your operation, investing in a more expensive and higher quality grow box makes sense.

Keep in mind that a grow box using full spectrum LED grow lights will cost more than one with HID or CFL lights… but it will save you lots of money in the long run when it comes to:

2. The Ongoing Utility Bills

You are looking for an efficient grow box. Hot systems are inefficient and cost more to run than cool systems. That means that HIDs are the most expensive to run, followed by CFLs with LEDs being the cheapest option in terms of electric bills.

Bear in mind that Grow Box kits will also have fans running and hydro systems will have air and/or water pumps running too. However electricity consumption of these components is negligible by comparison.
Use this simple calculation to figure out the cost of running your grow box:

What does the lamp cost?

The electric company charges you by the kilowatt hour, which is 1000 Watts per hour.
A 400 Watt bulb uses 40% of a kilowatt hour. A 250 Watt bulb uses 25%. If you are using LED lights, consider their “actual Watts” to do this calculation. You can find that information for the best LED grow lights on the market on our LED Grow Light Review page.

Take a look at your electric bill to find the price you pay per unit (remember, the unit is 1 kilowatt hour).

For example:

You pay $0.15 per kilowatt hour.

You are using a 400 Watt HID grow light.

400 ÷ 1000 = 0.4 (that’s the 40% of a kilowatt hour your grow light uses)
0.4 kilowatt hours x $0.15 = $0.06 per hour
In this example, it costs you 6 cents to run your grow light for one hour. Simply multiply this number by the number of hours you plan to run the light in a month and you can figure out your monthly electric bill.
You should do it, the answer is quite often a nice surprise as growing weed indoors doesn’t need to be as expensive as most people think.


Noise is an obvious cause for concern when thinking about stealth. Low hums and the noise of water trickling can seem almost inaudible during the daytime but sound deafening in the dead of night.

Luckily most of the stealth Grow Boxes use components designed to run quietly. Read carefully what they say about noise and don’t be afraid to contact them and ask for more information. Most of them say something along the lines of ‘whisper quiet’. This means not silent, but around about as loud as the background noise in a quiet library. If your neighbors are behind walls, they will never hear it. If the people that you don’t want to hear the noise are in the same house, then you should opt for a system that claims to be completely silent.

The main source of noise from a cabinet grow is from the fans. Again it is safe to say that the better quality fans will run the quietest. This is reflected in price so you will need to balance your need for stealth with your budget. If a Grow Box uses a branded fan, such as the Mortgage Lifter 3.0 which uses a Phresh fan, you can proceed with more confidence and check out the brand to see what others are saying about them.


Camouflage Marijuana

The appearance of a Grow Box is key to stealthy growing. Think camouflage. If it is something that is going to be in an area of your home that has people passing through you will want something that does not look out of place.

The Locker type Grow Boxes, such as the Super Locker 3.0 look really like boring office furniture and allow the eye to slip over them without taking too much notice. For the maximum in stealth appearance you could consider a PC Grow Box. A PC tower humming away quietly to itself in the corner of a room is something that nobody would normally look twice at.

    Jack – How many oz can someone grow out the 16.grow box since it has large grows?

    That obviously depends on you, what you are using, what you are growing, etc. So there is no true way to give an answer without it being purely a guess.
