How We Chose the Best Marijuana Seeds Bank

When we looked for the best marijuana seed banks, reputation, strain varieties, and additional products such as grow kits were our priorities.

Reputation and Customer Reviews

First, we made sure that each cannabis seed bank had overall positive reviews on consumer sites such as Reviews.io and Kiyoh. Stores with an average rating over 4/5 stars stood out to us. 

Breeders

Seed banks mostly offer strains from other breeders, alongside some of their in-house genetics. A quality seed store sources strains from reputable breeders known for developing highly potent, viable plants. 

Promotions and Discounts

It's no secret that cannabis seeds can be expensive, as prices of $7-10 or more add up with larger orders. That's why regular promotional offers such as free seeds and BOGO deals were necessary to earn banks a spot on this review. 

Strain Varieties

With several thousand varieties of cannabis out there, a quality seed bank must offer at least a few hundred strains. 

Major strain categories include feminized strains, autoflowering cannabis seeds, and fast strains that feature rapid growth. There must also be a wide range of effects from the soothing anti-inflammatory CBD strains to invigorating sativas and sleep-inducing indicas. 

Flavor and aroma were important to us, too. Your favorites may be woody or earthy aromas, musk, diesel, tropical mango or pineapple, chocolate, or even cheese. 

Growing Kits

Brand-new cannabis cultivators can benefit from complete growing kits. These include seeds, nutrients, and plant protectors, so you can spend more time growing weed and less time researching the perfect formulations. 

Germination Guarantees

Germination guarantees give you security in case none or not enough of your seeds sprout. Although germination guides are easy to follow, sometimes seeds turn out to be duds despite your best efforts.  

Pricing, Shipping, and Return Policy

The expense and logistics behind shipping weed seeds can put many potential growers off getting started. 

That's why we chose seed banks with discreet shipping, fair prices, and customer guarantees. Our most important customer guarantees concern germination and lost orders.

Factors to Consider When Choosing the Best Weed Seeds

Potency, your growing skills, other cannabinoids, and whether you want a specialized variant such as autoflowering cannabis seeds are key factors when finding your “best” seeds. 

THC Content and Effects

Cannabis seeds can produce plants with anywhere from trace amounts to over 30% THC. Always check the listed THC content before making any purchase, even if the strain name sounds similar to another with the potency you’re looking for. 

Additionally, a sativa- and indica-dominant strain will each have very different effects. Sativa plants are more energizing and uplifting, while indicas are sedative and more likely to cause couch-lock. Hybrid strains are somewhere in the middle, for example, a calming body buzz but an invigorating head high. 

Growing Difficulty

Each strain has its own nutrient requirements, ideal climate, vulnerability to pests, and tolerance ranges for factors such as temperature and pH.  

Some cannabis seed banks have beginner-friendly collections, such as ILGM. They include White Widow autoflower seeds, Maui Wowie feminized, and Sour Diesel autoflower seeds. 

Feminized vs Autoflower Seeds

Feminized and autoflowering cannabis seeds each have their own benefits. 

Feminized variants will almost always become female plants, which produce the cannabinoid- and terpene-rich buds you’re looking for. Just one male plant can fertilize an entire crop, shifting the flowers to seed production. 

Autoflower seeds reach the flowering stage at a pre-determined time, so you don’t need to worry about the hours of light exposure they receive. This is because their Cannabis ruderalis genetics adapted to harsh Siberian climates that provide short periods in which they can flower.

Any seeds that don’t specifically have “autoflowering seeds” in their description are photoperiod seeds. Photoperiod strains will only start the flowering period when the “daylight” hours shorten, so you have to plant them at the right time or adjust your grow light.

CBD & Other Cannabinoids

Your ideal cannabis seeds may produce plants high in CBD, such as Harlequin. There are also a few strains with less well-known cannabinoids, including CBG-Force and high-THCV Diet Durban. 

These may have additional or different therapeutic benefits. For example, CBG may be a stronger antioxidant than CBD, and CBC could help regulate cell division [1]. THCV could benefit metabolic health and may have its own anti-inflammatory properties. CBN, which increases as the leaves age, could promote sleep [2]. 

Indoor vs Outdoor Seeds

Next, where you can or want to grow your cannabis plants can affect your options. Plants that grow to a compact size and are mold-resistant are great indoor strains, but those that need a lot of airflow could be better outside. 

For example, the short Northern Lights suits indoor cultivation well. Tall Acapulco Gold may need an outdoor setup, and so may sunshine-loving Sour Diesel. 

Growing Season and Climate

As a general rule, the environmental conditions of the plants’ origins will tell you their ideal climate. ILGM categorizes seeds by Cool, Continental, Temperate, Steppe, Mediterranean, Sunny, Tropical, and Mold-Resistant.

It’s also important to consider the time of year you want to grow weed. Autoflowering cannabis seeds may reach the flowering stage at any time. Photoperiod plants need you to control their light conditions or plant them in summer so they will flower at the regular time in the fall.
