If you’re interested in growing cannabis, you may be wondering where to start. While there’s plenty of debate regarding hydroponics vs soil, indoor vs. outdoor growing, and other elements of growing marijuana, there’s one component to pay attention to the most: High-quality cannabis seeds.
Without the right cannabis seed, all of your efforts will be for nothing because you won’t be able to grow suitable crops for harvesting. But where can you get high-quality cannabis seeds? Fortunately, online seed banks allow you to get what you need to be shipped directly to your door.
Don’t worry if you’re unsure how to buy cannabis seeds online. We’ll show you the top four online seed banks and explain how they work so you can start growing premium cannabis seeds.
Seed Supreme is probably the most well-known and highly regarded in the industry compared to other online banks. Many reliable sources come to this seed bank again and again for all their needs.
Part of what makes Seed Supreme so desirable is that it offers a germination guarantee with all of its marijuana seeds. If you buy cannabis seeds online, there’s an inherent risk to the practice, but Seed Supreme gives you some extra peace of mind. That said, you must germinate your seeds within 90 days; otherwise, you will void the guarantee.
Another reason we chose this cannabis seed bank as our “best overall” pick is that it sells high-quality marijuana strains. Some examples include Royal Queen Seeds, Blue Dream, Northern Lights, and Granddaddy Purple.
You can also find rare seed strains that may not be available at other seed banks. Overall, Seed Supreme has over 4,000 unique seeds from 1,500 growers.

A cannabis seed bank is a business that harvests and sells marijuana seeds to buyers. Because cannabis is a dioecious plant, it requires both male and female plants to thrive. Female seeds are typically germinated by male pollen, helping to create new strains and varieties.
However, not all seed banks are equal. Some are better than others, and some banks specialize in a particular type of seed. The type of cannabis seed you buy matters because it will affect your growing capabilities.
A cannabis seed bank should allow you to choose specific strains and seed types. The more variety, the better the bank.
Although there aren’t too many marijuana seed banks online, it’s still imperative to choose the best one for your needs. Whether you’re a new grower trying to refine your skills or a commercial grower who needs consistent results, you must work with reputable seed banks to get the job done.
Here are the criteria we used to create this list to ensure confidence in our picks.
Any seed bank will contain a mixture of regular, feminized, and auto-flowering cannabis seeds. However, we chose the best cannabis seed banks based on strain variety and quality. Since the strain makes each crop valuable, we emphasized banks offering top-selling and unique strains.
Overall, we like seed banks that have a wide selection and consistent output. Reputable seed banks have repeat customers and plenty of options for everyone.
All reputable seed banks will offer guaranteed germination with their seeds. Because many marijuana seeds fail to germinate, this guarantee helps you feel confident that your money will go to good use. Even if you get free seeds from a supplier, you don’t want to waste valuable time and resources on non-starter seeds. Free seeds sound amazing, but reputable seed banks will help you find both auto-flowering seeds and high-quality seeds for an affordable price.
The primary benefit of shopping at an online seed bank is that you can have seeds delivered to your business directly. However, this convenience only matters if the delivery timeline makes sense. If you have to wait weeks or months for your seeds to arrive, that kind of defeats the purpose, as you’ll miss most of the growing season.
One downside of working with an online seed bank is paying for shipping. Since you’re not visiting a physical business, you have to take on shipping and delivery costs. Fortunately, sites like Seed Supreme offer free shipping, giving you leaner operating costs and ensuring you can make more from each crop.
You know better than anyone the size and scope of your cannabis-growing business. So, you must look at different factors to ensure that an online seed bank can meet your needs, both now and in the future. Here are some elements to pay attention to when comparing options.
We pay attention to customer ratings and reviews to verify whether a business delivers on its promises. For you, customer reviews can provide valuable insight into the inner workings of an online seed bank. Reviews can help you identify other growers with operations like yours so you can verify whether a seed bank can help you get to the next stage.
Autoflowering seeds are great for some strains, while feminized seeds are better for others. While seed banks may carry all kinds of different seeds, you know what will work best for your operation. Also, some sites specialize in a particular type, meaning they are better (or worse) for your needs than others.
For example, if you’re trying to breed new strains, you may want regular seeds. However, if a bank mainly focuses on feminized and auto-flowering seeds, you may not be able to find the right strains for your business.
Similarly, perhaps you’re looking for hemp seeds so you can grow THCA flower or delta 8 plants. Some banks may offer excellent hemp seeds, while others may only focus on traditional cannabis.
If you’re new to the world of growing cannabis, you probably don’t have all the essential tools, nutrients, and know-how to grow a substantial crop. Grow kits make this process much easier, and they’ll help you master the basics until you get your operation up and running.
Sites like Homegrown Cannabis Co. offer grow kits for different strains and seed types. These kits will give you an edge and ensure you get the best yield from your seeds. Even if you’re an experienced grower, kits can still streamline the process, especially if you’re trying new strains or seed types.
The convenience of shopping at an online seed bank allows you to pick and choose the strains and plant types. However, if a bank doesn’t service your area or it costs a lot more to reach your business, you’ll have to find another option.
Ideally, you can find a seed bank located in your state, so you don’t have to worry about federal cannabis laws. However, seed banks typically have methods of ensuring your shipment can move between state lines quickly and effortlessly if necessary.
While cannabis seeds are unlike most other types of products, you should still have access to a robust customer service center. The easier they make it to address concerns or issues with your seeds, the easier it will be to remedy the situation.
Ideally, seed banks should have multiple points of contact, and they should reply to your messages or calls within 24 hours (on business days, at least). If you have to wait days or weeks for a response, that’s a clear sign you should switch providers ASAP.
No matter which online seed bank you use, you’ll have to pick from one of three basic cannabis seed varieties. Here’s a quick overview of the three types: auto-flowering cannabis seeds, feminized cannabis seeds, and regular seeds.
One thing to point out with these seed varieties is that they’re only available for traditional cannabis plants. These days, consumer demand for different cannabinoids is more varied than ever, so you might need seeds for other purposes.
For example, if you’re trying to produce CBD products, you want hemp seeds with a high amount of CBD and low THC. Similarly, if you’re trying to create delta 8 or THCA products, you still need hemp seeds that contain as much of these specific cannabinoids as possible.
Not all seed banks offer these kinds of seeds, and you may need to reach out to determine whether your top choice sells hemp seeds.
Growing cannabis can be a rewarding and fulfilling practice, whether you’re doing it for yourself or to sell cannabis to others. In most states where recreational weed is legal, individuals can grow up to a certain number of plants in their household without incurring fines or jail time.
That said, the process of growing cannabis seeds into full-blown plants requires patience, knowledge, and vigilance. Here are some top tips for getting the most out of your purchase.
As a rule, cannabis seeds need much water, sunlight, and heat to germinate effectively. One of the best ways to get your seeds to sprout is to put them in a water bath with a heat lamp nearby. Once you notice the seeds germinating, you can transfer them to a pot or trench, depending on how you plan to grow your crops.
Another popular germination method is to use a wet paper towel. Keep the towel moist until the seed germinates, then transfer it to nutrient-rich soil.
If you’re growing commercially, it’s not feasible to germinate your seeds separately and then transfer them to dirt. Instead, you’ll have to plant them, water them, and monitor them diligently until they start sprouting.
Cannabis can be a high-yield crop if you know what you’re doing. However, these plants require constant care and attention, especially if you’re growing indoors. If you live in an area where cannabis thrives (i.e., Southern California), you can likely get away with planting your new seeds outside. Otherwise, you’ll have to monitor everything from UV light to temperature and humidity.
Because of the amount of work required, you don’t want to plant too many seeds at once. In fact, if this is your first time growing marijuana, you may want to start with one or two plants, so you get a sense of what it takes to cultivate this crop.
Another point to remember is the size of the plant. As a rule, auto-flowering cannabis seeds will grow shorter, making them ideal for indoor operations. They’ll also mature faster, so you can get a full crop in less time than you would with regular or feminized weed seeds.
But if you plant regular cannabis plants, they can often reach heights of 10 or 12 feet when fully mature. If you don’t have that kind of space available, you’ll either have to get creative with how you grow your plants or switch to a shorter alternative.
If you look online, you’ll see all kinds of tutorials regarding how to grow, manage, cultivate, and harvest cannabis plants. Now that weed is more mainstream than ever, growers are sharing all kinds of secrets and unique tricks to maximize their crop yields.
While trying as many of these techniques as possible with your own crops may be tempting, you don’t want to bite off more than you can chew. Even if growing cannabis is your full-time occupation, learning and mastering these tricks takes time.
Instead, pick a few plants and practice specific methods. Some common cultivation techniques include:
Don’t try to do too much at once, especially to a single plant. Depending on your entire operation, you may discover that some training methods are better than others. Master the ones that make the most difference and work from there.
Yes, feminized seeds are the best if you’re looking for consistent cannabis cultivation and minimal risks to your crops. Because feminized cannabis seeds won’t create pollinating males, you can spend less time inspecting your plants and more time cultivating high-quality buds and flowers.
If you’re trying to create your own cannabis strains, you should start with regular seeds. This way, you have complete control over the pollination process, including which strains breed together. Although this process is time-consuming and requires much diligence, it’s worth it if you can create popular proprietary strains that customers like.
Cannabis is a hardy plant, meaning that most of its seeds should germinate with the right methods. On average, you can expect up to 90 or 95 percent of all cannabis seeds to germinate. However, that percentage can drop fast if you don’t handle them correctly or offer them enough water and nutrients.
If stored properly, you should be able to germinate cannabis seeds within five years. In some cases, seeds may still be viable after 10 years, but they’re more likely to fail. As a rule, you want the freshest seeds possible when starting a new crop. If you’re holding onto cannabis seeds, rotate them every couple of years.
As anyone will tell you, cannabis cultivation is a long and arduous process. However, if you don’t start with the best cannabis seed, it doesn’t matter how high-tech or all-natural your growing operation is. Now that you know which reputable seed banks are available, you can start buying top-tier strains and maximizing the yield from each crop.
Best of all, as you expand your operation, these seed banks can help you cultivate more strains and boost sales accordingly. Happy growing!
