Stealth Grow Boxes

For many indoor growers, stealth is of the utmost importance. A successful marijuana grow can give itself away in a variety of ways, not all of which are obvious. You need to conceal odors, insulate light, and minimize noise. Stealth hydroponic grow boxes offer a reliable all-in-one solution for the safety-conscious grower.

It is true that most grow boxes are designed with stealth in mind, but the actual degree of security varies in each model. We’ve looked through all the options on the market and chosen the stealthiest grow boxes for your next secret grow. Since the keyword here is stealth, the grow boxes were selected based on minimalistic looks, quietness, and lights (as they can be a serious source of heat).

Choosing a Grow Box

Before presenting the actual grow boxes, we should take a moment and think stealthy. What is important in a secret grow? While some answers are more obvious than others, it is useful to have the full picture. That’s why we’ve put together a handy list of the most important safety features to consider when choosing a discreet grow box:


Cannabis can get smelly, especially during flowering. The worst part is that you can easily get used to it (especially if you spend a lot of time tending your garden). Unfortunately, your neighbors’ noses are much more sensitive. Your grow box should be as odor-less as possible.


Light emitting from a closet in your garage or bedroom is suspicious –to say the least. Unless you have some phenomenal excuse to give, it is better to avoid light leaks altogether.


Same goes with heat. File cabinets that emit heat are quite unusual and people can get suspicious. Lights are a major source of heat, so LEDs and CFLs are the best choices for your grow boxes (with LEDs holding a slight edge over their counterparts due to their more advanced technology).


Again, humming and buzzing and fans rattling in your filing cabinets? Again, LEDs can help you with that, as they require less heating. Ergo, less noisy fans. However, it is impossible to avoid ventilation, so you should opt for quieter models.


Stealth grow boxes should not be the pinnacle of design. They should be boring and insignificant, at least on the outside. You don’t want anyone paying attention to them, so choose accordingly.


At the end of the day, a grow box must fit your budget while still providing all the stealth features you need. This article features choices to suit all budgets.
Of course, a grow box must above all suit your particular needs. If possible, decide on the strain you want to grow beforehand. Consider the plant’s capacity and potential yields. whether it has single or dual chambers and whether it is set-up for a hydroponic or soil grow. For more details about choosing a great grow cabinet or tent for growing marijuana, check out our Grow Box/Tents sections.


As we all know, the wonderfully pungent smell of ripe cannabis can easily become 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.stealth-grow-box-odor-controlThere are two ways stealth grow boxes combat odors:
  • 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;
    • The ONA Gel is the most popular odor absorbing gel. It comes in jars and using it is a breeze. You just open the jar in the near your grow (not in the same room) and voilá! It will neutralize the smell automatically. They will last about 5 weeks before needing replacement.
  • Carbon Filters/Scrubbers
    • Carbon filtration is your best option for a total peace 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;
    • Exhaust systems will generally measure about 6” in diameter. If you haven’t bought your set up yet, always go for a 6” sizing for your fan, ducting and filter. Smaller models are barely enough for low-scale operations and 8” versions are intended for monster commercial yields;
    • Brand name carbon filters like are better than generic versions. Sad but true, where stealth is concerned the most expensive choice is often the most effective. VIVOSUN and Phat Filters are some solid brands;
    • Fan power is measured in Cubic Feet of air per Minute (CFM). Your fan should be powerful enough to pull air through your filter, so choose one with an equal or lower CFM rating than your inline fan;
    • Installing the carbon filter – You should fit the carbon filter at the opposite end of the exhaust system to the fan. The filter should be as far away as possible from your external vent, which will minimize the risk of the cannabis smell escaping.


Strange lights coming from cabinets, attics and spare rooms or tents can also be a telltale sign that there's a bit of indoor gardening going on. It is important that all of the light stays inside the cabinet. However, this is not the only reason. Lighting in indoor marijuana grows, is basically mimicking the actual sunlight that the plant is supposed to take at the respective season. When a plants' life starts, it expects the sunlight period to last a lot longer than the darkness period. As the seasons progress, sunlight decreases and the plant realizes that the time for flowering comes. Pre-flowering marijuana needs 12 hours of undisturbed darkness and 12 hours of light. Therefore, it is crucial that no natural light is penetrating the grow room during the dark cycles. If there is one in your grow box, you should immediately insulate it with a special lightproof tape.grow-box-lighting-stealthA good Grow Box will be completely light-tight and insulated to keep the light in. More on marijuana grow lights here.

Temperature Control

Whilst heat signatures can be a problem for big grow ops, even small localized heat signatures can cause trouble. Warm air will be vented through your grow box’s ventilation system, so choose the spot you will place it carefully. It would be best to avoid places in which visitors go. A ventilating file cabinet might become quite the spectacle for prying eyes.grow-box-temperature-control

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 have earned a place as the Holy Grail of low heat cannabis lighting. However, they are not a universal solution and you should still check out our light guide to determine which type suits your needs.Reflection - Most stealth grow boxes are insulated 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. The cost of setting up (which is one-off) and the utility bills, that are recurring. In most cases, it is actually better to invest in quality products. They will end up saving you more money in the long run.

The Setting Up 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 higher quality grow box makes sense.grow-box-budget-control

The Ongoing Utility Bills

You are looking for an efficient grow box. Hot systems are the opposite of that and cost more to run than cool systems. 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 example to estimate the cost of running your grow box:Electricity costs may vary across states, but on average it is about $0.30/kWh. A 250W light uses 25% of the kWh.For the purposes of this demonstration, let’s assume you are growing only one plant with an average of 150W. With an $.0.30/kWh rate, your monthly electricity costs (for the lights ONLY) should be around $25 (if we assume that the lamps will be on for an average of 18h/day). That’s about $0.80 per day! It is worth mentioning that $0.30 is considerably more than average than the regular electricity costs in the USA. Chances are that electricity will cost much lower than that!Take a look at your electric bill to find the price you pay per unit (remember, the unit is 1-kilowatt hour).


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 might want to rethink the whereabouts of your operation altogether (unless you find a device that runs in full silence).grow-box-noise-controlThe main source of noise from a cabinet grow comes from the fans. It is safe to say that the better quality fans will run the quietest. Bear in mind that the quality is reflected in the price more often than not, 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 (not featured here) which uses a Phresh fan, you can proceed with more confidence and check out the brand to see what others are saying about them.If you believe that the noise your fan makes is too much for you, then you should consider getting a fan silencer or muffler. These can help diminish the noise from your inline fan by up to 50%. You can attach them to either the intake side or exhaust side of an inline fan, or for maximum noise reduction attach to both sides of the fan. However, there is a slight downside: mufflers and silencers slow down the air flow through your system by about 10%. Silent Bob silencers and Phat Mufflers are good choices for a stealthy grow box.


The appearance of a Grow Box is key to stealthy growing. Think camouflage. If it is something that is going to be in crowded area of your home, you will want something that blends seamlessly with the environment.grow-box-appearance-stealth-controlThe 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.

Best Stealth Seeds for Your New Grow Box

Strain genetics play a huge role in the development of a plant. Some breeds are engineered specifically for indoor growing. Through years of research, seed banks are now able to offer some great deals on cannabis that will thrive in your grow box!The criteria of a stealth strain are rather obvious: it should be as odor-free and short as possible while maintaining a strong yield. Although there is little you can do about the odor, bear in mind that you can always train your plants to grow wider, maximizing the area light penetrates. You can read about the different techniques here. It may take some time, but the rewards are well worth it.However, there are definitely some strains that are more compatible to stealth grows.

    Here’s a problem, how do you open and close tents without releasing the smell and how do you dry your cannabis without smell using these methods. Im thinking of building my own with an airlock chamber. Two zipper dooors and you dont exit until youve used a carbon filter to deodorize the airlock room. But i dont know if ill have enough room inside to trim harvest and dry… Hmmm

    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.
