  • The 7 Best Grow Box for Beginners – Reviews 2021

    1. TopoGrow LED Grow Tent Complete Kit – Best Overall

    TopoGrow LED Grow Tent Complete Kit

    The last thing a beginner grower wants to do is order a grow box, then have to make a trip to the hardware store and a garden supply store just to get started.

    What TopoGrow does with their grow tent kits is nothing short of amazing. Available in a variety of sizes to fit the needs of anyone with space restrictions, every one of their more than 12 offerings comes completely ready to go, right out of the box. Suitable for both hydroponic and soil growing, all you’ll need to get started is seeds, water, and soil!

    This 48”x48”x80” grow tent setup is small enough to fit snugly within most closets, but large enough to accommodate plenty of plants as you gain more confidence in your cannabis grows. While its cost is a significant initial investment and it may not be the prettiest option on our list, we absolutely love this grow box for its completeness and ease of use.

    Pros
    • Complete kit; just add seeds, water, and soil
    • Many available sizes to suit any space
    • Can be used for hydroponic or soil based growing
    Cons
    • Mylar and plastic construction aren’t very attractive
    • Initial investment cost is pretty steep

    2. TopoGrow UFO LED Growing System – Best Value

    TopoGrow UFO LED Growing System

    The same company that made our #1 pick for a grow box also has an amazing value-priced option for a complete grow kit. Neat!

    By cutting the available growing space in half, this 24”x24”x48” grow box also cost only about half as much — while still coming with everything you need to get your grow started. This includes the tent, an LED grow light, and a full fan, filter, and ducting setup.

    At such an affordable price, just needing to add seeds makes this the best grow box for beginners for the money. If you don’t have plans on expanding beyond a half dozen plants or so, this kit could easily be the only one you ever need to buy.

    The clunky aesthetics of this tent are one of the few downsides of the kit. Made of mylar and plastic, it’s definitely not going to win any beauty competitions. But if you’re looking for function over form, it’d be hard to find a better beginner grow box.

    Pros
    • Incredibly affordable option for a whole grow kit
    • Small footprint easily fits in any standard-sized closet
    • Can be used for hydroponic or soil based growing
    Cons
    • Mylar and plastic construction
    • Small size will eventually limit how many plants you can grow

    3. Grobo Premium Grow Box – Premium Choice

    Grobo Premium Grow Box

    The Grobo Premium Grow Box looks and acts like something pulled straight out of a sci-fi movie. Of all the grow boxes on our list, it’s perhaps the only one that you could proudly display in your living room.

    Glowing purple door? Check. Space-age design? Check. Automatic plant growing system? Check. While we’re on the fence about whether all of these trippy features justify its staggering cost, you can’t deny that it is genuinely one-of-a-kind in the field of grow boxes.

    By including a system that senses and controls pH levels, nutrient concentration, airflow, humidity, light, and temperature, Grobo takes the guesswork out of your indoor grow. Aside from trimming your plants, the box will take care of everything.

    If it weren’t for the price, this beautiful contraption would have easily made it into our top 2. For anyone who has the money to spare, it’s both a beautiful and highly functional system for your indoor grow.

    Pros
    • Beautiful design and aesthetics
    • Automated growing system takes the guesswork out of beginner grows
    • Fully customizable growing parameters controlled via app
    Cons
    • Very pricey
    • Limited growing space
    • Might look out of place if it’s not on a spaceship

    4. Grow Box USA Grow Box

    Grow Box USA Hydroponic Grow Box

    There are plenty of reasons for wanting to keep your indoor cannabis grow completely private. Whether you’re keeping your fragile plants away from children, don’t want the neighbors’ opinions, or just don’t like the odor in your home, a stealth grow box is your best option.

    “The Stanley” is an excellent option for anyone looking to keep their indoor grow as discreet as possible. It comes with everything you need for a hydroponic growing setup, leaving you with only the responsibility of procuring the seeds and refilling a water tank.

    Available as a flat black or flat white locking cabinet, its ventilation system and sealed odor control barrier left us impressed with how easy it was to pay no attention to. Placed in the back of a closet, you might even forget that it’s there.

    Growers’ opinions differ on whether hydroponics are the best method for growing cannabis, though. It’s unlikely that the debate between water-grown and soil-grown bud will end anytime soon, so let us summarize it for you: Hydroponics are convenient and easy to adjust, but they may not produce as much or as potent of flower as soil growing.

    This grow box isn’t the biggest one available for the price, but when you need maximum stealth, it’s the clear choice.

    Pros
    • Completely hidden
    • Odor Free
    • Lockable
    • Complete hydroponic growing system
    Cons
    • Small growing area
    • Cannot accommodate soil growing

    5. SuperCloset Deluxe 3.0 Grow Box

    SuperCloset Deluxe 3.0 Grow Box

    SuperCloset has a pretty stellar reputation among indoor growers. Backed up by 10 years of sales, they’ve become one of the most popular fully automated grow cabinets on the market.

    Styled like a classic armoire, the SuperFlower 3.0 model prioritizes function over form. If you’re looking to get a consistent grow from the first day you set up your kit to the last, this grow box should be your first stop.

    Basically, they’ve set up a system that does all the work of growing for you hydroponically. The jury is out on whether hydroponics are the best way to grow cannabis, but this 16-plant system definitely does make the whole process extremely easy and reliable. Besides trimming your plants, everything else is taken care of inside the box.

    A 3-year warranty is included on every part of this kit, which definitely helps to cushion the blow of this system’s cost. If you’re looking for an all-in-one, hands-off solution that’s quite stealthy, be prepared to lay down some cash for it.

    Pros
    • Sleek and stealthy design
    • Fully automated system
    • 3-year warranty on every part
    • Everything included to get your grow started immediately
    Cons
    • Expensive
    • Hydroponic growing only

    6. Hellogrower HG24 LED Grow Box

    Hellogrower HG24 Stealth LED Grow Box

    So, what if you’re looking for the smallest, most economical grow system available — but need to keep it hidden? That’s where this Hellogrower mini stealth cabinet really shines.

    At a diminutive 20-inch size, you won’t be growing any particularly large plants in this one. In fact, some growers use this cabinet for the seeding and veg phase, but move to a larger tent for the growth of flowering.

    For the price, this all-included hydroponic grow kit is a great way to get started growing in as stealthy a manner as possible. However, you shouldn’t expect complete odor absorption; growers have pointed out that it doesn’t make a perfect seal.

    Pros
    • Smallest stealth model available
    • Inexpensive way to get started growing anywhere
    • Comes with everything you need (except the seeds)
    Cons
    • Very small; limits total yield
    • Not completely odor proof
    • Quickly grown out of

    7. PollenWizard Grow Cabinet

    PollenWizard ET-2XL Grow Cabinet

    For a top-of-the-line growing experience designed for professional growers, this cabinet from PollenWizard is a strong competitor. Promising harvests in 90 days, they even have a stackable “clone home” that can be used for continual 60-day harvests.

    Boasting precision digital controls through a bluetooth-connected app, this cabinet is specifically made for professional quality indoor cannabis growing. Even the fans are optimized for this, using a dual ball bearing design to completely eliminate condensation, mold, and mildew.

    If you’re serious about investing in a cabinet that will quickly and consistently produce harvests every 60-90 days, you could do a lot worse than to choose the PollenWizard ET-2XL. Of course, this growing consistency comes with a hefty price tag that puts it out of the range of most casual growers.

    Pros
    • Harvests in 90 days
    • Optional add-on for clones leads to continual 60-day harvests
    • Super high efficiency fan eliminates mold and mildew problems
    Cons
    • One of the most expensive grow boxes on our list
    • You’ll need to buy hydroponic accessories and nutrients to get started

    Buyer’s Guide

    When you’re trying to decide on which grow box is the absolute best for you, there are three essential questions to ask yourself:

    1. How Much Space Do You Have?

    Grow boxes can be as small as a breadbox, or as big as the guest room in your home. Do you have a closet to dedicate to your indoor grow? If so, grab a tape measure and take some dimensions. Keep those measurements handy while you browse through grow box options.

    Just remember: The bigger your grow box, the bigger your potential harvest. Whenever possible, choose the largest tent that you can afford and make room for; this will pay great dividends as you continue to collect more plants.

    2. Do You Need to Keep it Stealthy?

    Look, we don’t really need to know why you’d like to keep your indoor grow private… Just that sometimes, you’ll want it completely discreet. If this is the case, you’ll definitely want to go for a locking, stealth grow box that does a great job of keeping odors sealed in. Put it in the back of your closet, and no one will be the wiser.

    Alternatively, if you don’t need to keep your plants away from prying eyes, feel free to choose either a particularly large grow box to take up your guest room. Or, if you’re feeling especially classy about the whole grow operation, why not a decorative box that can double as a conversation piece in your living room?

    3. What’s Your Budget?

    There are grow boxes out there for everything from the $50 DIY project with Elmer’s glue and particle board, to $2000+ pieces with space-age technology.

    When budgeting for a grow box, look first at the size: How many plants do you want to grow? For larger operations you’ll need a bigger grow tent, plain and simple. Every added feature after that will help you ensure a bigger, more consistent grow — and add to the total cost.


    Conclusion

    Choosing a grow box for your first few grows doesn’t need to be entirely nerve-wracking.
