Since it is equipped with CFL bulbs, it won’t overheat, and you’ll also get 24-hour timers so you can adjust the lights automatically.

How Does a Grow Box Work?

If you’re interested in growing marijuana in a grow box, it will help you to first know exactly how it works. A grow cabinet produces an environment that is quite similar to the effects produced by Mother Nature – however, you will have more control over the light, humidity, and other factors, since everything will be enclosed in one tiny box.

These devices allow you to control every aspect of growing weed, from the ventilation to the light and the water. You won’t have to rely on the weather (or even the strength of your own memory!) in order to produce a healthy environment for your plants. You also don’t need to worry about bugs or diseases.

An indoor marijuana grow box is not only effective at producing high, healthy yields of marijuana, but it’s also small and discreet. Nobody will be able to spy on you or wonder what you are growing. You can often leave them for weeks at a time without having to do anything at all. Long story short, marijuana grow box is a smart investment, even for someone who is just starting out with growing weed.

Benefits of Using a Grow Box

There are many advantages to using a hidden grow box. Not only does one of these all-in-one grow boxes help to hide your growing operation, but it can perform several other vital functions, too.

A weed incubator is generally equipped with everything to help you get started. Although not as all-inclusive as one of the best marijuana grow tent kits, a grow cabinet will usually come with high-quality LED grow lights, filters and fans for improved airflow and ventilation, and reflective interiors that will distribute light to all of your plants.

The best single plant grow boxes will also give you other features, too. You might get one that has timers, pumps, pH adjusters to accommodate poor soil pH, nutrients, and more. You might even get potting soil included with your grow box! Most grow boxes provide ample light during all growing conditions, including the vegetative and flowering state, along with locking capabilities to protect your automated grow box from prying eyes.

The best grow cabinet will also be highly adaptable. You will be able to adjust everything from the lighting to the humidity, temperature, and ventilation. Some even allow for changes in your watering schedule. An enclosed grow cabinet will help you produce the best indoor weed possible because you will be in charge of every aspect of your growing environment. You can grow clones, seedlings, and even mature plants inside a weed incubator, and you can even produce soil or hydroponic crops like vegetables and herbs, too.

One of these units doesn’t have to be a small grow box to be compact, either. Grow tents are frequently used by indoor growers, but these can be bulkier and will take up significantly more room than a small grow cabinet. These tend to be only a couple feet tall and are quite narrow, which means you can save space and fit them into any indoor grow setting. They can be used in closes, bedrooms, apartments, garages, or anywhere else you have space to set one up. They’re lightweight and portable, with most taking only a few minutes to set up – so it won’t be a pain to change things around, either.

As we already mentioned, a hidden marijuana grow box will also be more discreet than its grow tent cousin. You won’t have to worry about your neighbors wondering what you have in your massive grow tent. A smell-proof grow cabinet will eliminate marijuana odors and it will look just like a file cabinet, storage locker, or dormitory refrigerator. Many of these require a key or code to open, giving you an additional level of protection. You won’t have to worry about anyone wondering what you are growing, because a grow box doesn’t even look like it could be growing anything.

Grow boxes have substantial odor control, which is helpful when you are growing marijuana. These are usually equipped with charcoal or carbon filters that will divert and disguise the smell of growing weed. Your room can remain free of odors!

And you don’t have to compromise the removal of odors for the quality of your crop, either. Grow cabinets produce some of the best yields and highest-quality weed. You won’t have to monitor or maintain anything – everything inside your grow box will handle all the work. You can grow weed year-round without having to worry about the climate, diseases, or any pests.

Finally, a good grow cabinet doesn’t have to be expensive. While these tend to come at higher prices than your standard grow tent, there’s a serious bargain here – remember, a good grow box is going to come with all of the components you need to get started, including your LED grow lights, filters, fans, and even your growing media. You won’t have to purchase these items separately, which can save you some time, money, and stress when you leave items out that you didn’t know you actually needed. You’ll get your money’s worth out of one of these economical units!

Recap

Hopefully, we have told you all the basic knowledge with our growing box reviews. Whether you are a unique hydroponics grower or prefer a more traditional style of growing weed, stealth grow box can help you meet your growing goals. You’ll have fantastic yields with marijuana grow box, and the best grow box on the market will make your job a lot easier – and a lot more discreet, too.

Are you thinking about growing and cultivating your own marijuana indoors? Make things more discreet by using these best marijuana grow boxes.

How to build an indoor cannabis garden on a budget

Setting up an indoor weed grow in your home is a lot easier than you may think. You will need to invest some time and money into an indoor grow, but acquiring materials and building it out doesn’t require a lot of skill and can be done cheaply.

This guide will show you how to build three different garden setups at three different price points. Each build below contains all necessary components needed to create a simple, climate-controlled grow for your plants.

All of the hardware used for each project can be ordered online or bought at a local hardware store or grow shop.

Note: Product prices below may fluctuate slightly over time.

The nano grow: $115 to $150

Who should use this build?

First-time growers, budget growers, and those who wish to keep their garden as inconspicuous as possible are a good fit for the Nano Grow. At 24”x 24”, this tent is small enough to fit in most closets.

Supply list:

  • TopoLight 24”x24”x48” Indoor Grow Room ($50)
  • Lorell 6” Clip On Fan ($14)
  • Century 24 Hour Mechanical Timer ($10)
  • Growstar 150w Cree LED Full Spectrum UFO Light ($43)
  • (Optional) iPower 4” 100CFM Inline Duct Fan ($18)
  • (Optional) AcuRite Hydrometer and Thermometer ($12)

Total cost: $117-147

The Nano Grow is designed to be the most budget friendly and least technical design. This build focuses on trimming down the necessary components to eliminate any superfluous items. While the essentials will cost you just under $120, you can add an optional inline fan and thermometer/hydrometer for just bit more.

LED lights work well in this environment because they produce very little heat. Although filtration for a grow of this size is not necessary, those who wish to grow in a more confined space should consider opting for the intake fan and thermometer/hydrometer. This will help to both increase air circulation and provide some fundamental metrics for maintaining a healthy environment for the plants.

With the tent height maxing out at 48”, plants grown in this space should not exceed 24” in height and we recommend using dwarf, indica, and auto-flowering varieties for best results.

Build notes:

30 min

  • Hardware recommendations: Duct tape, heavy-duty zip ties
  • Total power outlets required: 2 to 3
  • Where to assemble: Closet space or room
  • Recommended plant count: 1 to 2 plants
  • Components:

    • Tent: The Topolight grow tent is perfect for a small space or closet and features highly reflective mylar coating on the inside to help provide your plants with optimal lighting.
    • Light: The Growstar LED Full Spectrum UFO Light is an inexpensive and efficient fixture designed to provide a spectrum suitable for both vegetative and flowering plants. This light features 30w of Cree LED and emits a blue/purple hue. You also receive the necessary components to hang the light at variable heights in order to follow a canopy as it grows. LED lights do not add any additional heat to the tent and require less filtration to maintain proper temperatures.
    • Filtration: A 6” Lorell clip-on fan provides airflow within the tent. Additionally, you may add a 4” 100CFM inline duct fan to provide an intake mechanism to cycle clean air throughout the tent. If you decide to buy the intake duct fan, install it on the bottom of the tent using duct tape and zip ties. The clip-on fan will help move air around inside of the tent. By keeping the top duct port open, air may exhaust passively. If you decide to opt out of the intake duct fan, leave both the bottom and the top port open for air movement.
    • Automation: This build comes with a 24-hour mechanical timer designed to keep the light on an automated cycle. Mechanical timers are slightly more affordable than their digital counterparts.
    • Climate metering: The basic version of this build does not feature any climate monitoring hardware. However, there is an option to purchase an Acurite thermometer/hydrometer which will allow you to monitor essential metrics within the tent.

    The micro grow: $500

    Who should use this build?

    The Micro Grow is a value-driven package designed to provide all of the essentials for a single tent grow. More advanced than the Nano Grow, it’s a complete system that can handle just about any grow style.

    This build is a perfect fit for a small room or garage space. At 64” tall, the tent affords enough room to propagate most smaller, bushier cultivars. There is a canopy height limit of between 35” and 42”.

    In this setup, 2 to 4 plants are recommended. You can squeeze in 6 plants if you grow small auto-flowering varieties and/or vegetate the plants for less time.

    Supply list:

    • Casolly 32”x32”x64” Indoor Grow Room ($65)
    • Century 7 Day Heavy Duty Programmable Digital Timer, Dual Outlet ($13)
    • AcuRite Hydrometer and Thermometer ($12)
    • Lorell 6” Clip-On Fan ($17)
    • Growsun 4” Indoor Grow Exhaust Kit, Carbon Filter, Fan, Ducting ($120)
    • VivoSun 6” 240CFM Inline Duct Booster Fan ($21)
    • Growneer Variable Speed Vent Fan Controller ($12)
    • TopoGrow 315W CMH Grow Light Kit, 120v fixture w/ 3100k Bulb ($177)
    • 15 amp GFCI Grounded 5-Outlet Adapter ($29)

    Total cost: $466

    Unlike the Nano Grow, this build contains a complete ventilation system designed to filter and exhaust hot air while simultaneously bringing in clean, cool air. Additionally, the timer has been upgraded to the dual-outlet digital model for controlling both the light and carbon filter exhaust system. A variable speed vent fan controller is also added for maximum climate control.

    With the 315w CMH (ceramic metal halide) lights, enough heat is generated to recommend this build for an open space to allow for the best possible air circulation through the tent. The included 3100k bulb allows you to use the tent for both vegetative and flowering cycles.

    Build notes:

    1 hour

  • Hardware recommendations: Duct tape, heavy-duty zip ties
  • Total power outlets required: 4 (5-outlet grounded adaptor recommended)
  • Where to assemble: Room or garage
  • Recommended plant count: 2 to 4 plants
  • Components:

    • Tent: The Casolly 32”x32”x64” Indoor Grow Room provides adequate space for a much more powerful fixture, allowing you to cultivate more plants than the Nano Grow. This tent also features multiple ducting ports for proper air ventilation systems to be installed and comes with a front-sided concealable window for easy monitoring.
    • Light: This build features a 120v 315w CMH light fixture from TopoGrow. CMH lights give off far less heat than HID fixtures such as high-pressure sodium (HPS) and metal halide (MH). Complete with a 3100k bulb, this fixture produces a light spectrum conducive to both vegetative and flowering plants, eliminating the need to switch lights between cycles. Even better, this CMH fixture comes with a built-in ballast.
    • Filtration: Although CMH fixtures produce less heat than their competitors, there’s still a need for proper ducting and ventilation to remove hot air from the tent. For this build, we chose to pair a Growsun 4” indoor exhaust kit with a 6” Vivosun 240CFM inline duct booster fan. To maintain proper ventilation, a fan speed adjuster has been added. Additionally, a 6” Lorell clip-on-fan is used for airflow over the plant canopy.
    • Automation: A dual outlet digital timer is included for tandem use with the carbon filter exhaust and light fixture.
    • Climate metering: The Acuright Digital thermometer/hydrometer will help monitor temperature and humidity levels within the tent, making climate control adjustments easier.
    • Filtration setup: The 315w CMH generates enough heat to require filtration from the top of the tent. Airflow should be directed upward by installing the 6” duct booster fan at the bottom of the tent using duct tape and zip ties with the 4” carbon filter exhaust system at the top. Use heavy-duty zip ties to fasten the carbon filter at the back of the tent. Duct tape may be used to attach the fan to the filter as well as the filter to the aluminum ducting. Guide the ducting through the top port and fasten it with zip ties and duct tape.

    With this system, cool air will enter through the bottom of the tent, and warm air will be scrubbed as it leaves the top of the tent. The 6” clip-on fan should be placed just above canopy level on the back-left pole to help circulate air evenly as the plants mature.

    Standard grow: $1,000

    Who should use this build?

    The Standard Grow offers a complete package for growers who wish to maintain a perpetual cultivation operation year-round. It covers all of the essentials in housing, lighting, automation, and filtration for a standard home grow.

    No matter what your legal plant limit is, this tent should be able to handle it. At 80” for the main grow chamber, height is not a problem, and just about any cultivar can be propagated successfully under this build. With a 630w 3100k CMH fixture, this room can be used for both vegetative and flowering stages.

    For growers who want a full system capable of germinating seedlings, taking and keeping clones, maintaining mother plants, and have multiple chambers for various projects, this is the build for you.

    However, this system tends to run hot and will need the open air of a large room or garage to function optimally.

    Supply list:

    • 4 Bulb t5 Grow Light Fixture (x2 at $75)
    • GrowSun 6” 400 CFM Indoor Grow Exhaust Kit, Carbon Filter, Fan, Time, Ducting ($120)
    • TopoGrow 630W CMH Grow Light Kit, 120v Fixture w/ 2 3100k Bulbs ($320)
    • AcuRite Hydrometer and Thermometer (x2 at $12)
    • VivoSun 6” 240CFM Inline Duct Booster Fan (x2 at $21)
    • Lorell 6” Clip-On Fan (x4 at $17)
    • Century 7 Day Heavy Duty Programmable Digital Timer, Dual Outlet (x2 at $13)
    • TopoGrow 2-in-1 60”X48”X80” Dual Room Indoor Grow Tent ($188)

    Total cost: $938

    The “Standard Grow” is designed to be a fully comprehensive cannabis cultivation and propagation system, offering an all-inclusive perpetual grow space packed into a 4×5’ build. For just under $1,000, you get a 3-chambered, 3-light tent with a full air filtration system, automation and metering included.

    This build allows growers to cultivate at multiple stages in the plant’s life cycle as well as provide housing for multiple propagation projects.

    The 4×4’ main tent is powered by a 630w CMH light and the 1×4’ two-tiered tent extension is built out with two 4-bulb t5 fluorescent light fixtures. Complete with four fans, two dual outlet timers, and adjustable intake/exhaust components, this 80” tent supports even the most ambitious of grows.

    Build notes:

    2 hours

  • Hardware recommendations: Duct tape, heavy-duty zip ties
  • Total power outlets required: 10 (two 5-outlet grounded adaptors recommended)
  • Where to assemble: Room or garage
  • Recommended plant count: 4 to 12 (flowering)
  • Components:

    • Tent: The shining star of this build is the TopoGrow 2-in-1 60”x48”x80” dual-room indoor grow tent. The main chamber is 4’x4’x6.6” with an attached 1’x4’x6.6” two-tiered chamber. A wire frame separates the two chambers, allowing for two separate propagation rooms. The main and second chambers of the tent are divided by a velcro applied detachable, double-ended mylar fabric barrier.
    • Light: This system contains three separate light fixtures. The main room is outfitted with a 120v 630w CMH fixture with double 3100k bulbs, while the two-tiered chamber contains a pair of 12”x48” t5 fluorescent light bulb fixtures (4-bulb) stacked vertically. With this build, the main chamber may be used for both late vegetative and flowering cycles while the side chambers make for fantastic germination and cloning areas for young vegetative plants.
    • Filtration: The main chamber of the tent comes with a complete air filtration system. The intake is one 6” inline duct booster fan fastened at the bottom of the tent. A second 6” booster fan removes hot air from the top of the tent and sits just left of the CMH fixture. For exhaust, a 400CFM kit from GrowSun is used. The kit contains a 6” carbon filter, heavy-duty duct exhaust fan (with a speed controller), as well as 6” aluminum ducting. This system may either be fastened to the top back end of the tent via heavy-duty zip ties and duct tape or placed on the ground in the back right corner of the tent. Each set-up allows for exhaust ducting to leave the same top port. The main room receives two 6” clip-on fans, one set up to canopy height and the second fastened to a top support beam directing air towards the light fixture and 6” exhaust fan. The two-tiered side chamber gets a 6” clip-on fan for each room.
    • Automation: Two Dual Outlet Century 7 digital timers are used in this build. One controls the light and exhaust fan in the main chamber and the other controls the two fluorescent lights on the side.
    • Climate metering: Each chamber receives one Acurite hydrometer/thermometer for climate metering.
    • Filtration setup: For the main room, fasten the first 6” booster fan to the bottom-left port of the tent with zip ties and duct tape, directing air inward. The second booster fan should be fastened in the same way on the top-left side of the tent above the first. This fan will direct air out of the tent.

    The 6” exhaust kit may either be fastened on the top of the left tent or on the bottom-right, each option directing air through the carbon filter and out of the top port. This room receives two 6” clip-on fans—the first will be fastened to the top-right support beam of the tent to help move warm air towards the exhaust. The second fan can be placed on the back-left corner to follow the canopy as it rises.

    For the second room, a 6” clip-on fan is fastened to the back-left support beam of each tier to direct airflow throughout each small chamber.

    • All prices are factored in pre-tax/pre-shipping fees.
    • Pricing and availability are subject to change.
    • Although not included in the inventory list, it is highly recommended that you purchase both 4” and 6” protective screens for each booster fan. Though not available on Amazon currently, these can be purchased at most hardware stores.
