How We Selected the Best Cannabis Seed Banks Online

When selecting the best cannabis seed banks online, several factors were taken into account, including strain selection, discounts, guarantees, customer support, and helpful growing information.

1. Strain Selection

Strain selection was a critical factor in selecting the best cannabis seed banks on our list. We paid extra close attention to online seed banks that offered popular strains, exclusive strains, and even some hard-to-find strains. The quality of the strains and the variety of options available were also considered.

2. Discounts

We also paid close attention to online seed banks that offered discounts. While prices were comparable for all seed banks, we looked for sites that frequently ran holiday specials, newsletter coupons, and everyday discounts on bulk orders. This helped us identify the most cost-effective seed banks.

3. Guarantees

Seed banks that offered guarantees were also given priority. Most reputable seed banks have an 80% germination guarantee, which means 8 out of 10 seeds will germinate. If the seeds are worthless, most seed banks will send replacements. We looked for seed banks that offered the best guarantees to ensure customer satisfaction.

4. Customer Support

Customer support was another important factor in selecting the best cannabis seed banks online. While all online seed banks provide email support and some offer live chat, only a select few offer a toll-free phone number. We gave priority to seed banks that offered the best customer support options.

5. Helpful Growing Information

Finally, we paid close attention to the sites that offered detailed instructions for cannabis cultivation, including full-length guides, forums, or at the very least detailed text on the product page. This helped us identify seed banks that provide the most helpful growing information to their customers.

Buying Guide: Quick Tips

1. THC/CBD Content

When buying cannabis, it's important to consider the THC and CBD content. THC is the psychoactive component responsible for the "high" feeling, and higher THC content results in more intense effects. However, strains with less than 10% THC are considered mild, while those with 20% or more are recommended only for experienced smokers. CBD and other cannabinoids can also contribute to the effects, providing a more relaxed feeling.

2. Indoor vs Outdoor Growing

Some cannabis plants can grow both indoors and outdoors, but certain strains require temperature control and may do better indoors. Autoflower seeds are a good option for beginners, as they are easier to grow and require less attention.

3. Indica/Sativa Dominance

Indica strains are known for their sedative effects, making them a good choice for pain management and sleep aid. Sativa strains, on the other hand, offer more energy and creativity, providing a cerebral experience.

4. Special Usage

While the FDA has not officially approved medicinal cannabis or CBD for general medical treatments, many users have reported benefits for various medical conditions. It's important to research strains and their reported effects to find one that may be helpful.

5. Taste and Aroma

Taste and aroma can vary widely among strains, with some being sweet or sour and others having a more pungent smell. Traditional cannabis smells are often described as skunky or diesel-like, but can range from subtle to strong. When choosing a strain, it's important to consider both the effects and the taste and aroma.

Final Verdict

After conducting thorough research on various cannabis seed banks, Seed Supreme emerges as the top choice. The company impressed in all aspects, including variety, price, helpful information for beginners, and customer satisfaction. Seed Supreme also has a good reputation and provides reassuring guarantees.

For those residing in Canada, Crop King Seeds is a great alternative. With over 500 cannabis strains with excellent genetics and fast shipping, it's a reliable choice for Canadian customers.

As more U.S. states legalize or decriminalize cannabis, there's never been a better time to start growing your own. With high-quality seeds from reputable seed banks like Seed Supreme or Crop King Seeds, and some tender loving care, a lush harvest is within reach.
