How We Chose the Best Indoor Growing Kits: Ranking Criteria
Before we endorse any marijuana growing platform, we check five important benchmarks to see how each of the best seed banks measures up.
Brand Reputation
If a brand launched their own weed growing kit last week, you should probably stay away until it’s been solidified as a reputable choice. Our experts gave a higher ranking to cannabis banks that feature a long-standing reputation and plenty of customer reviews to back their claims.
Indoor Grow Kits
Unfortunately, not every marijuana seed bank can accommodate novice growers. While many popular platforms sell seeds and strains, we issued priority to marijuana banks that sell grow boxes and tent kits. You’ll have everything you need for a bountiful harvest!
Price & Discounts
Even though a marijuana grow kit saves consumers boatloads of cash on the backend, our experts searched high and low to promise the best value for your money. We gave a higher ranking to marijuana seed banks that offer rock-bottom pricing and deep discounts to boot.
Customer Support
Even for experienced cultivators, the process can feel overwhelming. If you need access to quick-responding support, not having a competent team at your disposal can make or break your first harvest! We prioritized THC seed banks with phone, chat, and email-based service.
Germination Guarantee
Not every platform can guarantee the quality of their marijuana plants, but you won’t find shady seed banks listed here. Sites like ILGM offer a 100% germination guarantee, which means you can expect a full refund if things go awry! Other sites have an 80% germination rate or higher.

How To Set Up a Grow Tent Kit
If it’s your first time trying to assemble a grow tent kit from scratch, you might feel compelled to scream in frustration. Before you drive yourself crazy, check out this simple guide to build your own grow tent with no hassle or stress involved! From there, mimic nature on your own terms.
Once you’ve created a grow tent, you won’t have to worry about creating a grow room – plus, you can deconstruct and move your entire setup within minutes. High-quality grow tents come with built-in holders for grow lights, ample space for electrical wiring, and a heavy-duty exterior.
A reflective Mylar exterior prevents light leakage and features room for observation windows.
Depending on the tent you purchase, the construction and setup process will look a bit different for each grower. However, it all boils down to assembling the frame and putting on the cloth.
After you’ve got a working grow tent, you may need to purchase LED grow lights and air ventilation equipment.
If you need to hide the smell of freshly sprouted cannabis, a carbon filter is optimal (but not required). Otherwise, it’s your time to shine – be sure to follow the lighting and temperature recommendations that come with your cannabis grow kit to enjoy the best possible results.

Pros of Using a Home Cannabis Grow Tent Kit
- Convenient: Say goodbye to outdoor grows, bugs, insects, and yield-ruining factors.
- Ideal Ventilation & Lighting System: You become the weather and have full control.
- Ease of Use: Even if you’re a first-timer, grow tent kits are designed for newbies.
- High Yields: When you have an optimal growing environment, you’ll get more flower.
Cons of Using An Indoor Cannabis Grow Kit
- Can Be Expensive to Set Up: A true hydroponic system can run you a pretty penny. Unlike quality weed, the hardware required may cost hundreds or thousands of dollars. We’d consider this a worthwhile investment when you consider dispensary THC prices.
- Limited Room for Expansion: If you want to get the best yields possible from your cannabis plants, you may wish to start growing weed in a grow room or larger space. Using small grow tents with indoor THC seeds limits your harvest to a 4×4 enclosure.
Some Factors To Consider Before Buying Your First Grow Kit
Here, we’ve listed some factors to consider when buying your first grow tent kit online.
Indoor Tent Size & Quality
Are you going to be using a grow tent or an indoor grow room? While the former is much easier to set up, you may wish to purchase low-volume or auto-flowering seeds if you won’t have the room to expand. Auto-flowering seeds produce smaller yields at double the speed of fem seeds.
Regular Soil or Hydroponics
If you’re willing to invest in an LED grow light and expensive hydroponics equipment, it’s in your best interests to purchase seeds that are optimized for quicker harvests. Many low-grade THC seeds don’t take to soil well, but indoor growers will find time-tested strains with our top picks.
Lighting & Temperature
Cannabis plants can be fickle on a good day, and optimizing your grow tent for temperature and lighting can spell the difference between healthy plants and duds. As you continue to grow cannabis, you’ll notice that various seeds require different lighting and temperature schedules.

Tips To Maximize Cannabis Yield With a Complete Growth Kit
Our team wants you to have the best soil or hydroponic growing experience possible! To that end, we’ve explained some helpful tips and tricks to maximize your plant growth and yields.
Regular vs. Feminized Seeds
Regular seeds have a 50/50 chance of developing into male and female cannabis plants. Male plants can contaminate female cannabis plants with pollen, leaving them unusable. However, male MJ plants are great for breeders and experienced cultivators on the hunt for free seeds.
Feminized seeds are best for consumers who don’t plan on creating the next Bubba Kush OG. Female seeds and auto-flowering fem seeds produce smokable, THC-filled buds.
Growing Medium & Environment
Even a small change in your growing medium & environment can directly influence your next harvest. Perfection is the goal, and you should read the directions on your growing kit with care.
Some indoor grow tent kits are designed to house certain kinds of marijuana seeds, and many popular strains respond beneficially to an LED grow light.
Different Styles of Growing Weed
You can grow weed any of ten million ways, and experienced growers will argue over the best method to kickstart your growing process. Plain dirt is the simplest way to grow anything, but you can use coco bricks as a medium to eliminate any quality problems with store-bought soil.
Hydroponic cultivation is responsible for today’s weed being 20x stronger than the stuff your dad smoked in the 70s. It involves growing weed in an inert medium such as gravel. You’ll need a special mixture of water and fertilizer to get larger yields and consume more potent cannabis.
Fresh Air Intake & Circulatory Fans
Stale, moist air is the worst enemy of a successful harvest. In order to achieve optimal yields, it’s important to circulate fresh air throughout your grow tent or grow room. This eliminates the potential for mold growth, excessive humidity, and a final product that doesn’t taste the same.

Where To Buy An Indoor Growing Kit Online: FAQs
In this section, we’ve addressed the most common questions people have about growing weed.
How Long Does It Take To Set Up a Cannabis Grow Kit?
You can set up a complete grow kit within minutes, but you’ll have to wait between eight and twelve weeks before seeing the fruits of your labor emerge. Any reputable indoor grow kit comes with step-by-step instructions, making it easy for novice cultivators to get started!
Is It Easy To Start Growing Marijuana Indoors?
No, it’s not easy to grow marijuana indoors. Depending on your indoor growth medium and environment, cultivating cannabis is a labor of love. You’ll need to be aware of lighting, temperature fluctuations, air circulation, and the potential for excess humidity and mold.
How Much Does it Cost To Grow One Marijuana Plant Indoors?
Based on a standard 600-watt grow tent, it costs approximately $100 to grow one marijuana plant indoors if you’re harvesting four times a year. On the backend, this works out to just
$1.56 per ounce assuming that you get a pound of flower with each successful harvest.
How High Will My Indoor Marijuana Plant Grow?
The height of your indoor marijuana may range from a few inches to several feet, even if you buy the same seeds. Really, the height and yield of each cannabis plant is influenced by the size of your grow tent or grow room. Like goldfish, marijuana plants adapt to their space.
>> Check the best prices at Seed Supreme
Is It Legal To Shop Cannabis Grow Kits in the Mail?
While it’s fully legal to purchase cannabis grow tent kits in the mail, using them can be a messy ordeal depending on your state of residence. Recreational cannabis has been legalized in 23 states, three U.S. territories, and Washington D.C. Eight states have decriminalized its usage.
Before you buy (or use) any weed growing kit or indoor grow kit, please check your local laws.
What Is the Best Cannabis Grow Kit?
The best indoor grow tent kit can be found at ILGM. Our experts fully endorse their Marijuana Grow Kit – Beginners. You’ll get 20 White Widow Auto-Flower seeds, a marijuana fertilizer set for 5-10 plants, and a Plant Protector for 20 plants when you buy this indoor grow kit today.
They’ve compiled everything you need to kickstart your indoor growing journey, and they’re running a 22% discount alongside $10 off. You’ll pick up their weed growing kit for $179.99! Free shipping, guaranteed delivery, and ILGM’s 100% germination rate add more incentives.
What Size Grow Bag Should I Use for Marijuana?
Our experts would recommend using a 5-gallon grow bag for your indoor marijuana grows. Having extra size prevents your seeds from becoming “root-bound” and failing to germinate. Additionally, a 5-gallon grow bag fits perfectly within any 4×4 grow tent or grow room setup.
Final Verdict: Where To Buy Marijuana Grow Kits Online in 2023
Marijuana grow kits require less effort and have better success rates than trying to figure it out on your own! When you cultivate quality weed indoors, you’ll save money and notice the benefits of supplying associated nutrients once it comes time for your first THC harvest.
Any reputable growing kit removes the stress, hassle, and frustration from cannabis cultivation with step-by-step instructions, high-quality seeds, targeted fertilizers, and weather protection. SeedSupreme is our top pick in 2023, but ILGM has a larger selection of regular grow tent kits.
Whether you’re compelled by Seed Supreme’s selection of 5,000+ indoor grow products or ILGM’s 100% indoor grow guarantee, you’re bound to have a positive first experience.
