Here’s How We Chose the Best Place to Buy Marijuana Seeds

We chose the best places to buy marijuana seeds based on several factors, including:

Online Seed Bank Reputation

We gave a higher ranking to seed banks that have been around the block. There’s no sense in buying from a company that opened their doors last week, especially when our top picks have navigated the cannabis industry for decades. Reputation and reviews mean everything to us.

Popular Strains + Selection

What good is a seed bank that doesn’t go above and beyond to feature fire strains in huge quantities? The best seed banks online give growers the option to buy regular seeds, grow feminized seeds, and create their own unique strains with time-tested cannabis genetics.

Lowest Prices Available

We prioritized seed banks with prices that equate to highway robbery. We gave a higher ranking to seed banks that aren’t afraid of a good discount, and making you feel appreciated is the best way for a company to guarantee your loyalty. It’s easy to say “yes” with rock-bottom prices. 

Customer Service Team

Whether you’re not hitting your desired harvest time or have any concerns as a new grower, you’ll have a competent agent at your disposal for any problems that arise. Our team gave priority to seed banks that offer 24/7 support via phone, live chat, social media, and email.

Here’s What You Should Know Before Buying Cannabis Seeds

Before buying the best Cannabis seeds, here’s what you should keep in mind.

Male Seeds vs. Female Seeds

Most cannabis seeds that you’ll find online are feminized seeds. Feminized pot seeds produce buds filled with THC! Of course, you can smoke these high-quality buds or convert them into a live resin oil for discreet usage. Only female cannabis plants are good for average consumers.

Male seeds pollinate female seeds and play an instrumental role in reproduction, but they’re not meant for consumers. As any experienced grower will tell you, they use male plants to cross-breed different cannabis genetics and create new strains while harvesting free seeds.

Regular Cannabis Seeds

Regular marijuana plants have a 50/50 chance of producing male and female seeds. However, you should remember that male cannabis plants can destroy female plants with excess pollen. To avoid the possibility of screwing up your first grow, keep male and female plants separated.

Regular plants are good for novice growers and people who want to save money on high-quality cannabis seeds! As we mentioned, male plants produce more hemp seeds.

Auto-Flower Seeds

Autoflower seeds are great for beginners and people who want to enjoy the fruits of their labor in record time. Autoflower seeds can be male or female, and the same distinctions apply here.

Autoflowering seeds rely on an internal clock, rather than external conditions, to produce buds within 75 days. Autoflower plants can be grown indoors or outdoors, and it’s very hard to mess them up! They’re bred using cannabis genetics from the unforgiving environment of Siberia.

While photoperiod plants require a certain amount of light and specific temperature to thrive, autoflowering seeds will bloom at warp speed regardless of any newbie mistakes you make.

THC Content, Indica/Sativa, and Terpenes

Cannabis cultivation is a complex topic, so we’ll just give you the rundown.

Before you pick any random seed bank or strain, you should consider the effects you want to experience. THC levels between 16-20% are best for novice smokers, but high-THC seeds may contain up to 30% THC. You shouldn’t overwhelm yourself with high potency right away.

Indica terpenes are responsible for making you feel sleepy and hungry while producing wave after wave of full-bodied euphoria. Sativa terpenes are on the opposite side of the spectrum! Sativa strains give their users a sense of heady well-being, energy, cognitive focus, and more.

Where to Buy Marijuana Seeds Online: FAQs

Here, we answer a few frequently asked questions about the best Marijuana seeds.

Is It Illegal To Buy Marijuana Seeds in the US?

No, it is not illegal to get marijuana seeds in the US. According to the 2018 Farm Bill [1], weed consumers in all 50 states are protected from legal persecution for simply possessing hemp seeds. However, some states have serious laws against growing high-quality cannabis seeds.

We’d encourage you to check your local laws before diving deeper into cannabis cultivation.

Which Is the Best Marijuana Seed To Get?

The best marijuana seed to get depends entirely on what you’re looking for! Our favorite strain happens to be Gorilla Glue #4 from Seed Supreme, but our top-rated seed bank stocks 1,500+ additional European cultivars. Look at the effect profile of each seed before making a decision.

Of course, there’s nothing stopping you from trying mix packs to pinpoint your favorite strains!

Which Marijuana Seeds Plant?

All the marijuana seeds listed here can be planted indoors or outdoors, depending on the strain you choose. As for beginner-friendliness, our team would suggest buying autoflower plants. Autoflower feminized seeds rapidly sprout THC buds within 6-8 weeks (this is quick).

Traditional feminized seeds can take up to 12 weeks before they’re ready for harvest.

Which Marijuana Seeds Produce the Most Buds?

Feminized cannabis seeds produce the most buds, but they’re a bit more difficult to grow. More specifically, you’ll enjoy much higher yields per harvest when using outdoor seeds. Outdoor seeds have more room to bloom, but they can take much longer to harvest than other options.

Outdoor marijuana seeds (like Mary Jane’s Grapefruit sativa strain) can yield up to 35 ounces of THC-filled buds per plant. You should have techniques dialed in before growing outdoors.

How Should I Store Marijuana Seeds?

You should store marijuana seeds by keeping them away from direct and indirect light. High-quality marijuana seeds can last for up to 5 years in a cool, dark, and dry area.

Aim to store your cannabis seeds in a room with constant temperatures between 42℉ and 46℉ (5℃ – 7℃). Ideally, your storage area should have humidity levels between 8% and 10%. However, these are perfect conditions, and your weed seeds will last a long time regardless.

Just grab a mason jar, add your seeds, put your jar in a drawer, and jack up the air conditioner.

How Long Do Marijuana Seeds Last?

As mentioned above, marijuana seeds can last for up to 5 years when stored using optimal conditions. However, for people who don’t have access to a cryotherapy freezing chamber, cannabis seeds last between 2 and 3 years. Remember that perfect is the enemy of good.

You may want to consider using your refrigerator as a storage unit (yes, the light turns off).  Experienced growers claim that chilled cannabis seeds can last a decade before expiring.
