Best Stealth Grow Boxes & Cabinets in 2021
The lights, CO2, hydroponic system, fans and water cooler are all automatic, so you can leave the grow box unattended for up to 15 days at a time. It is quiet, fully light proof and equipped with locks with two keys included. The air is filtered of odors by air scrubbers before being released from the box. This top-quality grow box is made of 16-gauge welded steel.
- Hydroponic system can be set for drip feeding of up to eight plants
- Aeration system and backup reservoir included
- Three dual-outlet grounded timers
- Internal CO2 boost bucket system
- pH adjusting kit
All these extras will ensure that your plants grow fast and well. You have about 4.5 square feet to work with if you get this box. LED grow boxes can have higher up-front costs, as LEDs are more expensive than other types of lighting. We suggest investing in them regardless because they draw less power, run cool, and last a long time. This is definitely top choice.
One of the most spectacular features of this hydroponic grow cabinet is its design. It’s made to fit in tight spaces, but still makes a lot of grow height available. Plus, it’s made with powder-coated steel and is very easy to lock. For those of you who feel nostalgic when you think of your early experiences with weed, the fact that this cabinet looks just like a gym locker will appeal a lot to you.
The full-spectrum Kind LED K3 adjustable grow lighting with T5 fluorescent side lights and small cloning chamber with two 24W T5 fluorescent bulbs generate intense, bright light with low heat output. An air pump quietly pulls air in, and it is filtered by an industrial grade carbon filter before being released again. A 132 GPH water pump supplies your plants with water.
- Digital thermometer and hygrometer
- pH adjusting kit
- Analog timer
- Total Dissolved Solids meter
The fans guarantee optimal air flow to every plant. You can start up to 14 plants in the cloning chamber and grow eight plants in the central chamber. The automated SuperPonics two-method hydroponics system is extra-efficient, combining bottom feed oxygenation with top feed watering. Now is the time to make your dream come true if you’ve always wanted to garden in a locker. This grow cabinet works perfectly, and it is also very affordable – always a nice advantage.
If you find the previous grow cabinets to be too big, the Supercloset Superbox might just be the best option. For weed lovers who want to start small and believe subtlety is all about the right dimensions, this small, but effective grow chamber is as subtle as it gets – it can easily be mistaken for a mini fridge. The warm-spectrum 200 W CFL system lets you grow up to eight plants.
- Amazing combo of Deep Water Culture, Bubble/Aeroponics, and Top Feed, ensuring healthy, rapidly growing plants
- Analog single light timer
- Total Dissolved Solids meter for hydro grows
- Temperature meter
- Humidity meter
If you prefer soil growing, this box will let you do that, but then you won’t be able to take advantage of the ten-gallon reservoir, which is kind of a downside. The fact that CFL lights generate more heat than LEDs should not worry you, because the Superbox offers as much air circulation and cooling as the bigger Supercloset boxes and cabinets. This helps prevent overheating in the room. The adjustable fan and carbon filter keep air circulating and feeling fresh. Even though this kit is significantly smaller, you still get all of the features you need to go through two grows, including growing medium and nutrients.
If you want to grow as many plants as possible, the Silverback is the best choice for you. This huge hydroponic closet can grow a minimum of three plants at a time. It’s the largest grow box by this manufacturer, which explains the name.
- Three 135W LED lights (no side lights)
- Eight exhaust fans and two intake fans to circulate air (through filters)
- Internal CO2 system
- Zero-maintenance water cooler and backup reservoir
- Cloning chamber with T5 fluorescent lights.
The cooler and reservoir provide stability to the hybrid drip feed system with built-in aeration that can feed up to nine plants at a time. Other advantages include four dual-outlet grounded timers, humidity and temperature meters, total dissolved solids and all other materials you need for your first two grows. All this fits perfectly in an impressive 16-gauge steel frame. If you want to automate this grow cabinet even more, you can buy an automatic pH adjuster. This cabinet is perfect for people who want epically large hydroponics systems.
This is the earlier version of the SuperLocker 3.0 we reviewed above. There are a number of key differences between the two, the price being just one of them. Indeed, the earlier generation is more suitable for the savvier growers.
Another, maybe more important difference is that the Superlocker 3.0 uses LED lighting, while the 2.0 uses HPS lighting. LED lighting throws off less heat than HPS lighting, but HPS lights are also quite strong. This discrete grow box features a cloning chamber at the top of the locker, where you can start a new plant, plus fans and air filters to keep the air smelling fresh and clean.
- 20 watt T5 fluorescent light that lights the cloning area
- Trellis included to help plants get strong enough to stand.
- Good-sized growing area
- HPS lighting
- Good low-cost alternative
- Grow plants up to three feet tall
You can keep the door locked with the included key and grow plants up to three feet tall. It might be easier to find the Superlocker 3.0 than this one even though the 2.0 has similar specifications – we suggest checking both out and comparing them. Finally, the Superlocker 2.0 is easy to stick in a corner – it won’t get in the way if space is an issue.
This enormous hydroponics grow box boasts three chambers: one vegetative chamber, one flowering chamber and one cloning chamber. This grow box lets you split your grow, optimizing one chamber for flowering and the other for vegetating, and each main chamber has capacity for up to 16 plants. The system is powered by dual water and air pumps and a 15-gallon reservoir.
- Growing chambers equipped with 450 W Kind LED K3 L450 grow light and T5 side lighting
- Cloning chamber equipped with two 24W T5 bulbs
- Adjustable shelf with room for up to 50 plants
- SuperPonics watering system combining Top Feed, Deep Water Culture, Bubble, and Aeroponics methods to ensure optimal plant development
The fans guarantee good air circulation, and the air leaving the box stays fresh thanks to the activated carbon filters. The system is equipped with a digital thermometer/hygrometer, pH adjustment kit and TDS meter. In sum, this hydroponic grow room is perfect for growing a lot of plants at once while remaining secure and not taking up too much space. Despite its size, it’s easy and simple to maintain regardless of whether you choose to use soil or go the water route.
Like the Grow Box USA Stanley, the SuperNova offers a little more floor space for those who need it. It features full-spectrum Kind K3 L450 LED grow light, and the light penetrates leaves more effectively thanks to the secondary optical lens included. T5 bulb side lights make sure the plants get light from all angles.
The SuperCloset Supernova is made of 16-gauge steel. You can lock it – key is included. The hydroponic system combines Deep Water Culture with drip feed to get the best of both worlds, ultimately achieving optimal plant growth. The Supernova lets you grow up to eight “mother” plants in the cloning chamber.
- 50-site SuperCloner cloning chamber lit with two 24W T5 bulbs
- SuperPonics system for mother plants
- Grow up to twelve plants at a time in the main chamber
- Automated airflow and hydroponics
- Fresh air guaranteed – internal fan pulls air through dual carbon filters before releasing it
- Four-port air pump and 185 GPH water pump to meet water demand
- Analog single timer enables user to set lighting schedule
- pH control kit
- TDS meter
- Hygrometer / thermometer to monitor your cabinet’s environment.
This is for all of you who want a cloning chamber with your Stanley grow box. The Stanley Max cloning chamber lets you launch your next grow sooner. Air filters clean the air before it is released into the room, and you have a lot of choices when it comes to automation as well. This package includes light, CO2, and watering automation as well as an automatic pH adjusting system, which is usually sold separately.
- Adjustable-height, bright and cool 480W LED lighting, can be switched between veg and flowering lighting
- 42W LED side light to maximize growth.
- Hydroponics: Deep Water Culture and Drip Feed combo with reservoir and water cooler
- Air and water pumps
- Runs quietly
This grow system lets you leave the plants unattended for up to two weeks at a time. The box looks like a large office closet, and it’s ideal for growers who want something bigger than the SuperLocker.
This hydroponic grow box is just the right size for laymen and pro growers alike. The cloning chamber is lighted by two 24 W T5 bulbs, letting you grow up to 50 plants at a time, while as many as 16 plants can be held in the main chamber, which is equipped with a 400W full spectrum HPS digital lighting system. Its dimness can be adjusted depending on your needs.
- 15-gallon reservoir
- Air pump
- 185 GPH water pump.
- Combo of top feed and Deep Water Culture watering methods for best growth
- Analog single timer to control the light cycle.
You can also adjust the pH with the included kit as you wish and monitor your grow box with a TDS meter and digital thermometer/hygrometer. The air is filtered by dual carbon filters to keep your grow room smelling fresh. The internal fans ensure great air circulation and flow to all of your plants.
You can also use the system to grow plants in soil if hydro growing isn’t your thing. We, however, would suggest the latter, among its many advantages being the option the water your plants automatically and get faster, healthier growth.
Finally, for those who want their grow rooms to be of actual room size, we present the Big Buddha Box Vertical Grow System. It features a 9×9 Gorilla Grow tent with all of the awesome details typical of SuperCloset designs. One upside of this grow tent is that you can make it up to eight feet tall using a height extension.
Unfortunately, it’s not as secure as the other grow rooms reviewed here and doesn’t come with a lock. Other than that, it’s absolutely great. It offers space for 75 plants, able to reach heights up to five times the average because there is more production than with typical horizontal grow setups.
- Watered with VerticalPonic ebb and flow hydroponics
- Two digital, air-cooled and dimmable 600W HPS lights
- Trellis system helping your plants grow faster and produce more
- Internal fans ensuring optimal airflow
- Phresh carbon filter to cleanse the air in the grow cabinet
You also get a digital thermometer/hygrometer, a TDS meter, analog single timers, and a pH control kit to maintain your environment according to your needs.
Everything to Know Before Buying a Stealth Grow Box or Cabinet
Now, a little bit more information on the key factors to look out for when buying a stealth grow box or cabinet. They are: automation, wattage, light proof, odor control, size, and light type.
If a grow box or cabinet is fully automated, that means it can function on its own, from which it follows that you don’t need to adjust it personally. All of the grow boxes reviewed here are fully automated, which ensures that you can leave the plants unattended for weeks at a time, and their health will not suffer. They’ll grow normally, and your life will be easier.
Wattage is linked to the brightness of the grow box or cabinet. It’s how you find out how much power the system will use. It’s also a common way of estimating how powerful the included lights are. Generally, the principle here is: the more, the better.
Listed as a percent, light proof indicates how sealed the system really is. The higher, the better. The best systems are very closed up. Low light proof will result in less effective growing and may also present a problem for plant growth at night. All of the grow boxes reviewed here are 100% light proof.
The higher the odor control percent is, the better. Odor control shows how good the grow box or closet is at keeping your premises from smelling like fertilizer and other substances that give off unpleasant odors. High odor control means the system utilizes filters, usually carbon, to clean the air in the box before releasing it into the room, so the air in your house will smell nice and fresh. All of the grow boxes reviewed here are 100% odor proof.
One of three light types is included in each grow system: LED, HPS, or CFL. The hottest of these light types is HPS, but on the upside, it also makes plants grow really fast. LED is energy efficient and cool, and CFL works well in small spaces, albeit needing adjustment now and then.
The size of a grow box varies depending on how big your plants are, how many plants you want to grow and how much floor space you have available.
Here’s the truth of the matter
Indoor grow boxes are the easiest way to grow from seed to harvest, that is full cycle. Indoor grow systems are ready to go, all-in-one solutions, which isn’t the case with DIY hydroponics, which requires lots of testing and adjustment. The best boxes are fully automated and include all pumps, fans, lights, filters, and everything else you need for a healthy, rapidly growing plant. They’re ideal for laymen and growers looking for big yields with minimal effort.
