How to Find the Best Seed Banks Online

There are a ton of options for seed banks online out there, and not all of them are reliable or trustworthy. Separating high-quality online seed banks from the rest can be tricky.

Luckily, we’ve picked out the best seed banks online for you to review. We examined five vital standards of service to make our choices. These factors can also provide a good guide when making your own choices of buying male plants, only female plants, hemp seeds, or high thc seeds.

Brand Reputations and Customer Reviews

The brand reputation of seed banks online reflects their reliability, overall quality, and customer service team. When it comes to cannabis cultivation, a widely-recognized brand will most likely offer excellent germination rates, yield, top-tier cannabis genetics, and discreet shipping.

One way to gauge the reputation or yield of the best seed banks online is to read customer reviews. First-hand experience from a grower or reviewers can inform you if the brand is worth trying to cultivate or not.

Of course, even the top seed banks online have bad reviews. So, make sure to carefully read every review to see if the brand’s positive side outweighs its negative side.

Germination Rate Guarantee

When your flowers or tomato plants don’t sprout, you may only be out a few dollars. If your cannabis seeds don’t germinate, you may have wasted considerably more money.

To take some of the risks out of buying popular cannabis seeds, the best seed banks online offer a germination guarantee for their seed quality while including grow kits that help you cultivate the marijuana seeds efficiently in your cannabis garden.

Essentially, if your marijuana seeds don’t at least sprout, the best seed banks online will send you replacements for free. Most seed banks online guarantee that 80% of their marijuana seeds will germinate, meaning that at least eight out of ten marijuana seeds will sprout.

The guarantee has some important limits. The guarantee doesn’t cover that sprouted plants will grow into healthy, flowering adults. It's only a guarantee that the quality weed seeds will sprout. You’ll also have to use the specific germination method that online seed banks require.

Strain Selection

There are a few famous strains that any online seed bank will probably carry, like afghan kush or girl scout cookies. However, there may be one specific strain or weed seed that does just what you need. The wider selection of cannabis strains means a seed bank is more likely to have the high-quality weed seeds you’re looking for.

The best seed banks online will also carry seeds from several online seed banks, seed producers, genetics, and growers. While they may carry the same strains, marijuana seeds sourced from different online seed banks will have subtly different effects and marijuana yield from every different grower.

The best online seed banks often package mixed packs of seeds , based on similar effects, growers, or related strains. It’s a great way to get a mix of seeds and try something new for less. It’s also a great way for beginners growing marijuana seeds to try a variety of options, even female plants.

Promotions and Discounts

The best seed banks online offer regular discounts, buy-one-get-one deals, and even a free seed with your order of quality weed seeds. Some seed banks online even offer loyalty programs, cheap weed seeds with discounts, or free seeds available in exchange for points.

Free seeds are one of the biggest benefits seed banks online offer regularly. You might even find a generous seed bank, like Quebec Cannabis Seeds , that offers a few free seeds with every order. Most options will include free seeds with larger orders of cannabis seed.

Prices, Shipping, and Returns

Prices are fairly consistent across most seed banks online. If you find a seed bank with prices much higher or lower than its competitors, that might be a red flag, especially the lowest prices. Checking customer reviews can often help reveal if you’ve found a great deal of high-quality weed seeds at the lowest prices or just another scam.

Shipping prices may have a bigger role when choosing between two online seed banks. Many offer free shipping , while more only offer free shipping with larger orders of high-quality seeds.

However, you shouldn’t skip options because online seed banks charge for shipping. Check out what you’re getting, high-quality seeds, for your money. Online tracking of your seeds and stealth shipping options may be worth paying more.

Returns are a relatively rare option with even the best seed banks online. Guaranteed shipping may be a more important option. If a shipment fails to arrive after a certain period, potentially because the seeds were seized, the seed bank will send you another shipment for free. Guaranteed shipping usually requires signing up for shipment tracking.

What to Look for When Shopping on Online Seed Banks

New to growing your own medical cannabis and wondering where to start? There are a lot of terms and types that get thrown around when looking through online seed banks, the best cannabis seeds, and their offerings.

We’ve broken down some of the most important so you can find the option that best fits your needs.

Indoor and Outdoor Seeds

As the name implies some varieties are better suited for growing in a controlled environment indoors. Other high-quality seeds are robust enough to be grown outdoors in the weather. Most high-quality seeds can be grown indoors or outdoors, though you may get slightly different results.

Indoor strains often have a stellar reputation for providing high yields or even stronger effects. Both marijuana seeds can be affected by the plant’s exposure to light. Growing indoors allows greater control of light exposure, which means you tune your technique to get the best results and high yields.

Growing Season and Climate

Some of the many strains available are better suited to warm and dry climates, while others are hardy enough to grow in cooler temperatures. The difference may matter more if you plan to grow your plants outside. For the best results, buy cannabis seeds that match your area’s climate.

Feminized and Autoflower Seeds

It’s important to keep male and female cannabis plants separate. A male plant will fertilize the flowering female plant, which prevents it from producing the high-quality buds you’re trying to grow. Experienced growers can pick out male plants before it’s a problem and remove them to produce high-quality buds. However, a mistake can ruin your whole crop and buds.

Feminized cannabis seeds don’t include any male seeds. . You can grow all your plants without worrying that a stray male will mess things up.

Autoflowering cannabis seeds are other great high-quality seeds options for beginner cannabis growers. Regular pot seeds need to be exposed to light in the correct amount and with the right timing in order to grow and flower. Autoflowering seeds don’t require the same attention. They’ll flower automatically as long as all our seeds are kept healthy and growing.

THC Content and Effects

Knowing the THC content of a cannabis strain will give you an idea of its potential psychoactive effects. The higher the THC content, the stronger its impact, making the person “high”.

The United States Federal Government set the legal limit for the THC content to at most 0.3% . Any concentration beyond that limit can induce harmful effects such as loss of appetite, sleep disruption, concentration problems, nausea, and hallucinations.

CBD & Other Cannabinoids

Cannabidiol (CBD) is a chemical compound extracted from the cannabis plant. It is the one that interacts with a person's endocannabinoid system, which plays an important role in homeostasis and regulating certain bodily functions. Higher CBD may induce significant medicinal effects that can potentially alleviate chronic pain, inflammation, and seizures [1].

Moreover, watch out for other cannabinoids present in the seed. For instance, a seed with a large THC content may induce euphoric effects. Other cannabinoids like cannabigerol (CNG) and cannabinol (CBN) might also induce different degrees of psychoactive effects in an individual.

Growing Difficulty

Choose seeds that require little to no effort to grow healthy. Autoflower seeds are best for beginners who want a hassle-free growing experience. You can grow them inside your home, as the seed quality doesn’t need light exposure.

Furthermore, choose strains in the cannabis industry that can withstand changing climates to ensure that they will have a constant growth rate and yield regardless of the humidity of the area where they are planted.

You may also want to pick seeds that grow quickly compared to other strains. For instance, weed seeds can grow within 8 to 9 weeks after being planted.
