How We Chose the Best Marijuana Seeds Online
With so many seeds and seed banks out there, how do you select the product for you? We used several criteria to choose the best marijuana seeds online.
THC Content and Potency
THC content directly feeds into how potent a seed strain is. Factoring in this fact, we wanted to choose marijuana seed strains that had high THC potential.
Still, we didn’t only select the highest THC seeds. We also checked out consumer reviews to ensure the high-quality seeds we shortlisted held their own giving fast and lasting rewards.
Yield
Seeds with promising yields set up growers with more value for their investment. Yield is particularly important to heavy marijuana smokers.
For this, we chose marijuana seed strains that are reputable for good yields. Even for the beginner marijuana strains, we made sure that they could give moderate to high yields of at least 14 oz.
Flowering Time
Ideally, you want to be able to harvest as fast as you can. So, we went with high-quality marijuana seeds that had relatively short average flowering times of 8–9 weeks. For the few that had slightly longer flowering times, we made sure they were worth the wait by giving plentiful yields.
Grow Kits
We also included seed banks that offer Marijuana grow kits, which are a convenient way to start growing your own cannabis at home. They usually contain everything you need to set up a successful grow, such as seeds, nutrients, pots, soil, lights, fans, filters and more.
ILGM is one of the most popular and trusted online sources for marijuana grow kits. They offer a variety of kits for different strains, sizes and budgets. Some of their best-selling kits are:
- Beginner Mixpack: This kit contains 3 easy-to-grow strains that are perfect for beginners: White Widow, AK-47 and Bubble Gum. You get 15 seeds (5 of each strain), enough to grow up to 1.5 pounds of buds. The kit also includes the Marijuana Plant Protector System, which protects your plants from pests, diseases and nutrient deficiencies.
- Gold Leaf Grow Kit: This kit contains 20 seeds of Gold Leaf, a potent and high-yielding strain that was created by ILGM’s founder Robert Bergman. You also get the Bergman’s Plant Food fertilizer set, which provides your plants with the optimal nutrients for each stage of growth. The kit also includes the Marijuana Plant Protector System.
- High Yield Mixpack: This kit contains 3 strains that are known for their massive yields: Amnesia Haze, Big Bud and Chocolope. You get 15 seeds (5 of each strain), enough to grow up to 3 pounds of buds. The kit also includes the Marijuana Plant Protector System.
Homegrown Cannabis Co. is another online store that sells high-quality marijuana grow kits. Here are some of their best-selling grow kits:
- Advanced Marijuana Grow Kit: This kit is for growers who want to enjoy the luxury of connoisseur-quality cannabis. It contains 4 seeds of Kyle Kushman’s Cherry AK, a potent and flavorful strain that produces crystal-covered buds. It also includes a full pack of organic nutrients, a bottle of Germ Genie, a kelp-based superfood that boosts germination and plant health, and a detailed program guide.

It contains 4 seeds of White Widow Auto, a frosty and potent strain that has a 12-week cycle from seed to harvest. It also includes a full pack of standard nutrients, a bottle of Germ Genie, and a program guide.
Growing Difficulty
No one wants a hard time when breeding their marijuana seeds…yep even experienced growers.
Putting grower convenience in mind, we were inclined to pick marijuana seeds that required moderate attention.
We additionally chose a few heavy-yielding marijuana strains that need more growing expertise to suit experienced growers that may fancy the challenge.
Germination and Delivery Guarantees
The truth is you could pick the best seeds and still get zero results—especially if you don’t get them from the best marijuana seed banks (more on this later).
This is why we made sure to recommend seeds that are sold with a germination guarantee.
If your seeds fail to sprout, you’ll simply get replacements.
Reputable Marijuana Seed Banks
We made sure to recommend only the best seed banks that ship to the United States.
This is because some online seed banks might say that they sell a particular strain (like White Widow), but they’re actually buying seeds in bulk and putting any label they want on them.
Therefore, you should avoid other seed banks that aren’t mentioned here unless you have some experience already and know where to buy marijuana seeds.

Buying Guide: How To Pick the Best Marijuana Seeds for You
Below, you’ll find a few things to consider before buying the best marijuana seeds online. Also, remember to go with reputable weed seed banks and avoid companies that nobody knows about.
Indica vs. Sativa
Indica and Sativa seeds eventually produce flowers with widely different effects.
Indica seeds tend to give more calming benefits, and hence work better for evening use. Sativa seeds on the other hand grow flowers with stimulating and energizing effects ideal for daytime use.
THC vs. CBD Content
You can use marijuana recreationally or medicinally.
If you’re all about the fun, then you should choose high-THC marijuana seeds. THC is the compound responsible for the ‘high’ effect people receive from marijuana.
For those fancying medicinal seeds, high CBD seeds will give you that with none to minimal highness.
Growing Marijuana Indoor vs. Outdoor
Different seeds needing different growing climates shouldn’t lock you out of breeding a particular seed.
If your natural climate doesn’t suit the seed you want to grow, you can grow it indoors in a controlled environment.
Seed strain is another major thing to consider when selecting a growing environment.
Indica seeds have pungent skunky aromas. If you want to keep your growing discrete, you’re better off planting Indica seed strains indoors. Moreover, since Indica plants grow stocky and bushy they’d fit well in an indoor space.
On the flip side, Sativa marijuana strains are sweet and spicy and can subsequently be bred outdoors comfortably. This said Sativa plants grow quite tall, so perhaps an outdoor growing space would work best.
Autoflowering vs. Regular vs Feminized
Marijuana seeds are grouped into three main categories:
Regular Seeds
Regular seeds contain both male and female seeds. Regular seeds might not be the best for marijuana production, however, they’re good if you want to breed new strains as you need male and female seeds for that.
Female Marijuana Seeds
Feminized seeds produce all female plants. In other words, with feminized seeds, you won’t have to lose space on useless males and you’ll avoid accidental pollination.
Autoflowering Seeds
Autoflowering seeds flower on their own. Moreover, they can be grown at any time of the year, which makes them pretty convenient. However, note that autoflower seeds can come in both regular and feminized formats.
