Factors to Consider When Choosing a Seed Bank
Plant genetics’ variety and quality, brand reputation, and customer support are critical factors when choosing seed banks.
Reputation and Reliability
First, ensure that the seed banks you are considering have a reputation for high-quality plant genetics and honest service. The best have award-winning strains from their own breeding programs and high ratings from experienced growers who know their stuff.
Seed Variety and Quality
A quality seed bank will have an index of hundreds of strains from breeders known for their strong genetics. Not only does seed diversity give you more choice, but it’s a sign that breeders want to partner with the bank.
Shipping and Delivery Options
Discreet delivery should be a standard feature of all cannabis seed banks because of factors such as the continued stigma around growing weed.
Some of the best seed banks offer stealth shipping. This method hides your weed seeds in a package with random items and does not display any indication of what you bought.
Customer Service and Support
Customer support services such as germination guarantees and replacement seeds, if your package fails to arrive, are important features.
Germination guarantees are a sign of integrity and a high success rate when sprouting seeds. Guarantees for lost packages show that the bank is committed to quality service, as buying seeds is expensive and can quickly burn a hole in your pocket.
Seed Bank Location and Regulations
As cannabis legalization grows worldwide, it’s important to remember that some countries completely forbid it. We recommend US-based seed banks the most as your package will pass over fewer borders.
Pricing and Payment Methods
The operational costs of running a cannabis seed bank and the products’ hard-to-find nature can burn a hole in your wallet. That’s why we looked for seeds priced at $7-10 or less and regular special offers.
Each bank also had to offer a range of payment methods, sometimes including cryptocurrency. Bitcoin is an accepted payment method in some seed banks such as Seed Supreme. This way, you can enjoy greater privacy.
Seed Bank Reviews and Feedback
Consumer review sites such as Reviews.io are a great way to research the real experience when ordering from seed banks.
Look for average ratings over 4-4.5/5 stars and positive comments on customer service and germination rates.

How to Order Seeds From a Seed Bank
First time ordering seeds? Here is a step-by-step guide to making your first purchase.
Research and Selection Process
Cannabis sativa and C. indica are diverse plant species, so it’s important to carefully consider the strain you want.
Perhaps you want delicious tropical fruit, berry, or vanilla notes, or you may prefer diesel aromas for nostalgia. Maybe you need a high-CBD strain for its medicinal properties, or you want a strain developed in harsher climates.
Placing an Order Online
Next, it’s time to order the number of seeds you want. As not every seed planted will germinate, it’s best to order 10% more than what you expect to grow. This also allows you to save genetic material or potentially participate in a seed savers’ exchange.
Payment Methods and Security
Only purchase weed seeds from seed banks that have secure payment. At a minimum, there must be a “https” in the address bar’s URL to indicate a degree of encryption. Choose the method you are most comfortable with when it comes to privacy.
Seed Supreme and some other online seed banks accept Bitcoin, and occasionally less-common cryptocurrencies. Using crypto gives you another layer of privacy as the transactions are difficult to track.
Shipping Policies and Options
Shipping policies will generally involve discreet shipping in plain packages with only the delivery instructions. You can add special instructions with some seed banks such as Herbies.
As the legal status of cannabis varies, many seed banks will say you are “officially” ordering as a collector. Starting up a weed version of the Svalbard Global Seed Vault sounds like a great project for biology lovers, and with so many strains on offer, we kind of encourage this too.
Tracking Your Order
Tracking your order gives you peace of mind when buying a still-controversial product, especially if you need medicinal cannabis. Some seed banks offer free tracking while others ask that you pay extra, but we recommend choosing this option regardless.
Receiving and Inspecting Your Seeds
As soon as you receive your seeds, store them in a cool, dark place until they are ready.
Before this, you must inspect each seed to ensure they are not damaged. Dark green cannabis seeds are also more likely to germinate than pale or light green seeds. It’s still best to try germinating them all so you can provide proof they were defective.
Customer Support and Follow-Up
If you have any questions or problems, ensure you know the customer service contact details. Follow them up if you don’t get an answer within a couple of days.

Tips for Successful Seed Germination
Seed germination is perhaps the most exciting and nerve-wracking part of growing cannabis. Here’s how to pull it off.
Choosing the Right Seeds
First, you must choose the right seeds for your preferences and climate. As a general rule, cannabis seeds grown in a similar environment to your region will do best in outdoor grows. If you’re growing them inside, make sure you can provide for their needs.
Preparing the Germination Environment
Each strain has different nutrient requirements, disease resistance, and ideal temperature ranges. Research these carefully before planting your seeds.
In general, you will need a shallow tray of soil or seed punnets to get started. A grow light, preferably 36 watts, or a well-lit but protected environment is also necessary.
Seed Soaking Techniques
A popular method of germination is on a wet paper towel, which allows you to see the first root and shoot.
You can also use a seedling mix of peat and coir, which is nutrient-rich but allows your seedlings to access oxygen. Oxygen levels help to prevent overwatering, too.
Germination Temperature and Humidity
During germination, the temperature should be around 21-29 degrees Celsius (70-85F). Humidity should ideally be 70-90%, but the seeds should not be wet.
Light and Darkness Requirements
Cannabis seeds must germinate in darkness if you use the wet paper towel method. Otherwise, they should be planted under grow lights and sit half an inch deep in the soil.
Monitoring and Troubleshooting Germination
Cannabis seeds can take 2-10 days to germinate. Otherwise, common reasons why they may not germinate include:
- Chlorinated tap water: Always heat your tap water and leave it outside overnight to let the chlorine evaporate
- Too much light: Turn down the grow light, or ensure the seeds are deep enough in the soil
- Dried-out seeds: It’s best to soak them for 12-18 hours in a wet paper towel or glass of water
- Add root growth microbes, which are available from specialty suppliers
- Use a low concentration of hydrogen peroxide or make tiny cracks with your fingernails to help open stubborn seed shells
Transplanting Seedlings to Soil
If you are using tiny punnet-sized pots for germination, transplant your seedlings before they grow past two inches, or after two or three weeks. Otherwise, root-binding can damage them and affect future growth.

FAQs
Here are some common questions among people who have decided to grow their own weed.
How Long Do Cannabis Seeds Last For?
