The reputable seed bank stocks over 4,400 strains, including auto-flowering seeds, fast-growing seeds, female seeds, high-THC/CBD seeds, regular seeds and Cup winners. Additionally, the company has a few good promotions, which we’ll see below. As mentioned above, Seedsman stocks 4,400+ strains from famous breeders, including Barney’s Farm, Dutch Passion, Nirvana Seeds and more. Some of their bestsellers are Black Sugar (up to 28-ounce yields), Strawberry Cheesecake, Runtz Muffin and Blue Dream, among others. Besides high-quality marijuana seeds, the seed bank also sells organic rolling papers and T-shirts for true fans. Besides email support, Seedsman has phone numbers in the U.S. and in Europe, which is better than ILGM.  However, it’s not as good as ILGM when it comes to germination guarantees since it doesn’t provide any. Instead, they judge each situation on a case-by-case basis, and according to most reviews, they’ll send free replacements if you get more than 20 percent of duds. Speaking about reviews, the seed bank has received 55,000+ of them, which shows that people are generally quite happy with the seeds they sell. If you check out the site, you’ll see that Seedsman’s prices are already lower than most seed vendors. Additionally, they also offer six free seeds on $60+ orders, and they run a few BOGO deals on select breeders (often including the aforementioned Barney’s Farm and Dutch Passion). Want to save even more? Then consider paying with Bitcoin. You’ll get 10 percent off, and you’ll be able to place an order anonymously. >> Check the best prices for seeds at Seedsman ILGM—Best for Feminized Seeds Strains have 1,000+ reviews100 percent germination guaranteeFree shipping to the U.S.Buy 10 get 10 free dealsActive growers forum Founded in 2012 with the sole purpose of providing helpful guides to beginner growers, I Love Growing Marijuana (ILGM) has grown to be the world’s best seed bank. Today, they offer a wide variety of strains, including auto-flowering cannabis seeds, beginner, fast-growing, high-THC, high-CBD and female seeds. ILGM stocks only a hundred weed strains, which is much less than other seed banks with thousands of seeds. However, the good news is that the reputable seed bank stocks all the most popular strains, including White Widow, Super Skunk, Gorilla Glue, etc. More importantly, each and every one of those weed strains has hundreds or thousands of reviews on the product page itself, which helps you see what kind of results other growers managed to get. As you probably know, ILGM is famous for its free shipping deal on every order (no minimum value). The seed bank is also known for its 100 percent germination guarantee, which is hard to beat in the industry. But when it comes to customer service, users’ ILGM reviews have revealed that a few other things stand out. The active forum is a great place to get advice from experienced growers on topics such as pruning, topping, low-stress training and more. You’ll also find hundreds of detailed guides on the website, and the famous Grow Bible is worth a read as well. You can also contact ILGM’s customer support team via email. Phone support would be better, but at least they’re pretty helpful and knowledgeable. Besides the shipping deal mentioned above, ILGM is also known for its “Buy 10 Get 10” promotions on a dozen of popular strains, including White Widow, Super Skunk and Super Silver Haze. However, these deals change often, so the strains on sale might be different when you read this article. >> Check the best prices for seeds at ILGM Herbies Seeds—Best Seed Bank for Freebies User-friendly website3,000+ seeds70 percent germination rateFree seeds and giftsStealth shipping Herbies offers autoflowering, Cup-winning, quick-growing, feminized cannabis seeds, high-THC/CBD strains and photoperiods. In fact, as we’ll see below, they stock more than 3,000 options from 100+ breeders, as well as their own marijuana seeds. Herbies manage to make this huge selection easy to browse through thanks to handy search filters—including THC content, climate, yield, price and more. Additionally, they stock a dozen ultra-high THC (30 percent+) seeds, including Apple Betty, Mimosa Shot and Cafe Racer. Other popular strains include Mimosa x Orange Punch, Purple Lemonade, Grandmommy Purple and Runtz Muffin. Herbies Seeds has a user-friendly website that will help beginners and advanced growers find what they need in just a few minutes. More importantly, they provide a 70 percent germination rate guarantee, which is almost as good as Crop King’s. They also provide phone support in the U.S., Europe and the UK. Every purchase from Herbies comes with a free seed, and for every $20 spent, you’ll get an additional seed at no cost. In addition, you receive nice freebies like pruning shears or a stash holder (it depends on how much you spend). >> Check the best prices for seeds at Herbies Seeds Crop King Seeds—Best Cannabis Seed bank in Canada 500+ marijuana seedsAssorted seed packsGermination guaranteeToll-free phone numberNew weed strains Founded in Canada in 2005, Crop King Seeds has made a name for itself for its stable genetics and reasonable prices. Besides classic strains like White Widow and Trainwreck autoflower seeds, they also release new strains all the time, so be sure to check that section if you want to try something exotic. While Crop King has many fewer strains than Seedsman, it still has a pretty good selection of 500+ auto-flowering, regular and feminized cannabis plants. Of course, these include Sativa strains, Indicas and Ruderalis strains, but also fast-version seeds for short seasons and high-CBD seeds for medical purposes. Here are some good cannabis seeds to try: Green Crack, Blue Cookies, Northern Lights and Amnesia Haze. Alternatively, you could also get an “assorted seed pack” that includes a few popular strains. Like ILGM, Crop King provides a germination guarantee, even though the rate is slightly lower (but still pretty good) at 80 percent. They offer free shipping as well, but only if you spend $200 or more. Most importantly, Crop King has the best customer support of any seed bank. You can use the 24/7 live chat or call the toll-free number to speak to a knowledgeable agent. Truth be told, Crop King isn’t the king of discounts… sure, you get 10 free seeds if you spend more than $420, but there are not many deals apart from that. To be fair, their prices are quite good already, and you can’t argue with their great seed quality. >> Check the best prices for seeds at Crop King Seeds Types of Cannabis Seeds Some of the popular types of cannabis seeds include: High CBD Seeds High CBD seeds are specially bred to produce plants rich in cannabidiol (CBD) while keeping THC levels low.  Ideal for users seeking therapeutic benefits without the high, these seeds are perfect for managing stress, anxiety, pain and inflammation. High CBD strains offer a relaxing, clear-headed experience. Photoperiod Seeds Photoperiod seeds require specific light cycles to transition from the vegetative stage to flowering. These seeds are a favorite among experienced growers due to their versatility and potential for high yields.  Photoperiod plants need 12 hours of darkness to initiate flowering, making them suitable for growers who can control lighting conditions. High THC Seeds High THC seeds are bred to produce plants with elevated levels of tetrahydrocannabinol (THC), the compound responsible for the “high” associated with cannabis.  These seeds are ideal for those looking for potent psychoactive effects, often favored by recreational users. High THC strains come in various flavors and effects, from energetic to deeply relaxing. High Yielding Seeds High yielding seeds are designed to produce larger harvests, making them a practical choice for growers aiming for maximum output.  These strains are optimized to generate more buds per plant, providing a rewarding experience for cultivators focused on productivity.  High-yield seeds are available in a variety of THC and CBD levels, appealing to both recreational and medicinal users. Fast Version Seeds Fast version seeds are created for growers who want a quick harvest. These strains have shorter flowering times, often reaching maturity in a few weeks. Ideal for growers with limited time or those in climates with shorter growing seasons, fast version seeds allow for faster cycles without sacrificing quality. Here are a few things to know before buying marijuana seeds online from online seed banks. How to Buy Cannabis Seeds Online Weed Seed Bank Reputation Male and female seeds may be purchased from any of a potentially endless number of online seed vendors; however, not all of these sources are legitimate. Learn more about how satisfied customers are with their services by reading reviews on independent websites like Trustpilot or Reddit. Germination and Shipping Guarantees You won’t have to pay for duds if you get too many seeds that don’t sprout. With a germination guarantee, you will be protected. Likewise, guaranteed shipping protects you against seeds being lost or seized by customs, which does happen occasionally. Indica or Sativa Seeds Online seed banks sell female plants in different types and strains. Sativas are typically taller with longer leaves, resulting in a “hippie” high. Contrarily, Indica strains are shorter and more calming than their Sativa counterparts. Recreational vs. Medical (CBD) Strains If you’re looking for the therapeutic benefits of weed, purchase high CBD marijuana seeds.  However, if you want to experience a psychoactive effect, go for high-THC marijuana seeds. Yield vs. Growing Ease The easiest seeds to grow usually give the lowest yields.  As you become more experienced, you should seek out more difficult-to-grow female plants and employ low-stress training techniques in order to achieve maximum yields of up to 1000 grams per plant. Begin with easy strains, of course. >> Check the best price for seeds at SeedSupreme FAQs Is It Legal To Buy Marijuana Seeds Online? Yes, it’s legal to buy marijuana seeds online if you live in a state that allows weed growing. That said, things have been a bit blurry since the 2018 Farm Bill that legalized hemp seeds—to the point that marijuana seeds are seldom confiscated anymore. To be safe, we recommend checking your local laws before you buy cannabis seeds online. Is SeedSupreme a Good Seed Bank? SeedSupreme is one of the best weed seed banks courtesy of its germination guarantee, free U.S. delivery, and regular sales and discounts. What Is The Best Weed Seed For Sale? The best weed seed for sale is Godfather OG, in our opinion. With a high THC content of up to 30 percent, this strain is particularly recommended for experienced smokers looking for a strong kick. What Weed Strain Should I Buy? You should buy the Jack Herer weed strain if you want a super easy cannabis plant that can grow indoors or outdoors. It gives pretty good yields and doesn’t need much water. How Long Do Weed Seeds Last? Marijuana seeds last up to 16 months if kept in a cool, dark place such as a refrigerator. If you want to keep them even longer (for up to 10 years), consider freezing them. How to Store Cannabis Seeds? You should store marijuana seeds in a cool, dark area (like a fridge, for instance). If you don’t plan to use your seeds within a year, we recommend placing them in the freezer. Should I Buy Regular, Autoflowering or Feminized Seeds? You should buy auto-flowering seeds if you’re a novice or feminized weed seeds if you have a bit of experience. Only true pros should consider regular seeds, though, as you have to be very careful with the male plants to avoid accidental pollination. Who Has the Best Autoflowering Seeds? Seed Supreme’s autoflowering seeds are top-tier, offering hassle-free cultivation and impressive yields. With their superior genetics and reliable performance, Seed Supreme stands out as the go-to choice for the best autoflowering seeds. How Many Cannabis Seeds Should I Buy? Will They All Survive? You should buy at least 5 marijuana seeds, as not all of them will survive, especially if this is your first time. That said, it could also be a good idea to buy 10 or 20 seeds at once to take advantage of a deal, such as ILGM’s BOGO deals. Which Seeds Is the Best Seed? The “best” seed depends on your goals. For high potency, High THC seeds are ideal; for therapeutic benefits, go with High CBD seeds.  High yielding seeds maximize harvests, while Fast version seeds are perfect for a quicker turnaround.  Wrapping Up If you want to grow healthy weed plants, you need to get your seeds from a reliable seed bank. SeedSupreme is a highly recommended seed bank if you want healthy seeds, discounts and a germination guarantee. Homegrown Cannabis Co is also worth considering, alongside the other seed vendors we have reviewed in this article.  Just one thing—before you begin growing weed plants, please check your state’s laws and regulations. Better be safe than sorry!
