An online seed bank is basically a platform or website that sells cannabis seeds on the internet instead of in a traditional brick-and-mortar store.
In fact, these online businesses excel at providing exceptional quality seeds, with unique genetics that might not be easily found at a local store.
Seed banks play a crucial role in preserving the genetic diversity of cannabis plants. They house a diverse range of strains for different purposes.
Whether you’re searching for select strains for breeding purposes, growing cannabis for therapeutic benefits, or in need of high-THC options for recreational use, online seed banks can connect you with the best possible seeds.
Why Buy Cannabis Seeds Online
There are many reasons to opt for marijuana seeds from an online seed seller. The best seed banks offer a number of advantages that physical stores just can’t beat. Here’s why:
Convenience
With online platforms, you no longer have to travel to make a purchase. You can easily browse and compare options from the comfort of your home. Whether you’re eyeing the highly popular Grandmommy Purple strain or trying out new strains, you can manage everything with just a few clicks.
Saves Money
Most online seed banks have the ability to offer much lower prices, since they do not have to worry about the overhead costs of running a physical store. This means they can offer competitive pricing, as well as frequent discounts, and attractive deals, like free seed offers. This makes growing cannabis plants a more wallet-friendly endeavour.
Larger Selection
Physical stores are also limited by storeroom and shelf space, but online seed banks can provide a more diverse range of options.
Instead of browsing a few hundred regular seed options, online websites and their nifty filters allow you to choose the perfect strain from thousands of varieties. So, you’ll always find something to fit your growing journey.
Range of Product Filters
As we mentioned, online platforms group cannabis seeds into useful categories. To further help users in their search, they also use filters to help customers select seeds based on their specific preferences.
Types of Cannabis Seeds
The first step in understanding which kind of cannabis seed to cultivate is understanding the different types of cannabis seeds available for cultivation, and the kinds of benefits they offer to growers.
Indica Seeds
Indica strains are known for their deeply relaxing effects. These cannabis plants grow best in controlled environments, with proper light schedules, and a well-managed airflow and temperature settings to trigger the lowering stage.
Sativa Seeds
Sativa strains are the perfect options for energy boosts and mental focus. Plants grown from Sativa seeds grow taller and require a bit more care. This means they are better suited for outdoor cultivation, where they can grow to their full potential.
Hybrids
Hybrids combine the best attributes of Indica and Sativa, balancing relaxation and stimulation. They are highly adaptable to various growing environments and are often bred for durability against pests and disease.
Photoperiod Seeds
Photoperiod seeds need manual light cycle changes to transition between growth stages. These seeds are better suited to experienced cultivators who wish to breed new strains.
Autoflower Seeds
Autoflower seeds are great for newbies because they automatically move from the vegetative phase to flowering without needing to adjust the light schedule. They grow faster and also require fewer resources.
Feminized Cannabis Seeds
Feminized seeds only grow female plants. This translates to better yields of exceptional quality smokable buds, and it also eliminates the hassle of separating male and female plants.
Red Flags to Avoid When Shopping for Cannabis Online
Unfortunately, not all online seed banks are created equal, and there are many unscrupulous websites out there willing to take advantage of unsuspecting new cannabis growers. This is why it is always important to shop at reputable and trusted seed sellers.
Overly Positive or Fake Reviews
Look out for overly enthusiastic and positive comments that feel manufactured, especially from users whose details are difficult to verify. Opt for providers with feedback from verified customers on trusted review platforms.
Lack of Clear Contact Information
Reliable companies like Seed Supreme and Herbies Seeds have clear contact details and great customer service that is not only responsive but knowledgeable on a variety of seed and order issues.
Too-Good-to-Be-True Pricing
If prices seem suspiciously low for high-quality strains, they probably are. This is usually an indication of subpar products, such as seeds that are no longer viable.
Missing Details on Shipping and Germination Guarantee
Good seed banks outline shipping and payment options upfront and often provide replacement or refund guarantees if your seeds fail to germinate.
However, some companies claim to offer these guarantees but include unreasonable requirements in their terms and conditions, which make getting a replacement almost impossible.

In the last several years, there’s been a surge in FDA approvals for what’s known as oral oncolytics. Oral oncolytics are targeted cancer therapies that come in tablet, capsule or liquid form that patients can take at home, rather than in an infusion clinic. Scripps physicians have seen exponential growth using this approach, with patients citing convenience as a major quality-of-life enhancement in their cancer treatment. This approach also allows treatments to be customized based on specific genetic mutations and a patient’s unique disease biology. Find out more about oral oncolytics here.
