Which Cannabis Strain Breeders Can I Trust?

Don’t you want the best-of-the-best cannabis genetics for your next grow? You can help ensure you get a great strain by starting with a great breeder. This article shares some of the most popular and reputable cannabis breeders, including information and recommended strains for each one. I’ve divided this tutorial into two parts. First I’ll give a list of recommended breeders and strains, then the second half will discuss the current state of genetics in the cannabis world.

Recommended Breeders of American Genetics

    – They offer modern genetics, but unlike the two examples below, they stabilize each strain in seed form so you can get the consistency of growing the same strain every time. I want to be able to come back and order the same strain if I like it, and Seed Supreme is (so far) one of the first breeders of American genetics I’ve found that offers that option. – Mostly offers “crosses”, which means they breed two good plants together and sell the seeds without much (if any) stabilization or back-crossing. Even though they don’t offer stabilized strains and their yields/results are variable, I included them on the list for people who don’t care as much about consistency and want to hunt for new phenotypes using modern genetics with lots of variation. – I like the strains I’ve grown from this breeder, but the seeds are EXPENSIVE. My friend who gave me some of these seeds paid $200 for 10 feminized seeds. I wouldn’t recommend them unless you plan on taking clones and doing a breeding program as the strains are not stabilized (same as Ethos) but if you’re looking for lots of new phenotypes to explore with cutting-edge genetics, this is another great choice. They release their strains in “drops” and it can be difficult to get your hands on their seeds. I recommend following them on their Instagram account to learn when and where to buy seeds for the next drop.

The Seed Supreme version of Platinum Cookies is something special

Recommended European Cannabis Breeders

These breeders have good reputations and stabilized genetics, which means their strain descriptions can be trusted. Although some of them do source some genetics from the USA, they primarily breed with genetics that have made it to Europe. Some of these genetics are difficult to find in the US, but often offer unique or interesting effects compared to the trendy American strains. European strains tend to be lower in THC (under 20%, though not always), which is great if you want more classic effects, but not the best choice if you want to feel overwhelmed by the bud effects. If you’re looking for “Face melter” strains, then I recommend sticking to the section of American breeders.

    – Barney’s Farm has been selling seeds out of Amsterdam since 1992, and they regularly develop new genetics and refine their lineup. In my experience, strains can be hit or miss, but I included Barney’s Farm on the list because they offer some real winners. When I’ve grown these strains, I’ve been consistently impressed: Acapulco Gold, Ayahuasca Purple, Cookies Kush, Liberty Haze (one of my favorite strains for daytime), LSD, Pineapple Chunk (best Pineapple strain I’ve grown) & Sweet Tooth. – Specializes in stabilizing strains to capture classic strains, clone-only strains, and other hard-to-find genetics in seed form – Sparkly strong buds (they also breed seeds under the name Reserva Privada) – Great all-around selection with something for everyone – potent, consistent results – delightful great-smelling buds

Pineapple Chunk is a quintessential European strain that continues to impress me I grew it in 2012, then 2015, and recently again in 2020. Every time the buds came out even better than the previous time. I personally think this may be Barney Farm’s best strain, and that explains why they keep refining it. This one was grown under an ES300 LED grow light in 2020 and smelled like a mix of citrus with a hint of strawberry. Buds came out dense and sparkly.

Recommended Autoflowering Breeders

Auto-flowering strains cannot be cloned and therefore have somewhat different breeding protocols vs standard (photoperiod) strains. On top of that, old auto-flowering genetics produce weak plants with low potency buds. Therefore it’s extremely important to use a breeder that’s got a high-quality (and current) auto-flowering breeding program. Many breeders produce great auto-flowering strains (Barney’s Farm, etc.), but the following breeders stand out for consistency and potency. Click the name of the breeder to see a list of their currently available auto-flowering strains.

    – sparkly and potent buds – feel-good potency, great choice for growers who struggle with anxiety – Excellent yields, classic effects – Fast and potent – Consistent (auto-flowering only) – unfortunately, they can’t seem to scale up their operations and strains sell out constantly (keep checking back or sign up for the newsletter on the bottom of the Mephisto website to get updates when they release batches of seeds) – Buds always come out beautiful (they look just like the pictures) and smell great. – fast germination, auto-flowering plants grow fast and vigorous – Spanish genetics with beautiful and colorful strains like Cream Caramel Auto – Dense high-quality buds that look and smell like photoperiod strains

Cinderella Jack Auto by Dutch Passion makes extra-potent, rock-hard buds with above-average yields. This little plant produced several ounces by itself.

Recommended Cannabis Strains

Now that I’ve given some examples of recommended breeders, I wanted to share some examples of particular strains that my friends and I have grown over the years and recommend. These are all great for beginners unless otherwise noted, and produce excellent buds.

These strain recommendations are based on…

Potency – THC & CBD content, plus does it have the described effects?

Bag Appeal – Bud structure, color, density, smell

Consistency – Do strains grow the way the breeder says they will? Do plant characteristics vary a lot from plant to plant of the same strain?

Ease of growing – General hardiness of strains

Reputation – Has this breeder earned an excellent reputation over the years?

Girl Scout Cookies

Girl Scout Cookies is a famous clone-only strain from California that has spawned countless copycats and been incorporated into other famous strains like Platinum Cookies. BlimBurn Seeds has captured the magic in their version so growers can see what Girl Scout Cookies is like without having to find a clone.

The BlimBurn version of Girl Scout Cookies produces excellent buds. They don’t always turn purple, but cooler night temperatures towards the last 2 weeks of flowering can help bring out purpling.

Liberty Haze

I am a huge fan of Liberty Haze. The bud effects remind me of the unique psychedelic “day” (uplifting) effects of now-rare outdoor Sativa strains. You never see them anymore because they get huge and need long hot summers in order to produce properly. Liberty Haze gives you access to those bud effects yet is suitable to grow indoors. It still tends to grow tall and stretchy, but as long as you top the plants when they’re small (cut off the tops, which forces the buds to makes many buds instead of one), you can wrangle them indoors.

The left plant here is the 2nd time I grew Liberty Haze. As you can see it got a bit tall, which I’ve come to expect, but it was otherwise easy to grow and produced excellent yields. The Critical Kush on the right was also a good plant, but the Liberty Haze buds won when it came to effects.

Example of a Liberty Haze plant sent in by a reader

Tangerine Dream

For the fruity lovers, Tangerine Dream smells great and produces beautiful buds.


This strain lives up to its name. Amnesia buds are known for making you forget what you were just saying. Not necessarily the best choice for social situations (unless you all just want to chill) but perfect for relaxation at the end of a long day.

Example of an Amnesia plant I grew in a hydroponic setup

Closeup of Amnesia buds. Dense and chunky!

Moby Dick

Moby Dick is a whale of a strain. The bud effects let you swim through life with THC levels that can hit 27%. However, it also has a good amount of CBD (1%), which means it’s much less likely to cause brains to dive down into a state of panic or anxiety (especially compared to high-THC strains that lack the calming gentle waves of CBD). Smoke a bud and sail through your mental stress into a state of relaxation.

Okay, that’s enough whale jokes, but seriously this is an excellent strain that’s easy to grow and produces high-quality buds. The one downside is it tends to get a bit tall, but as long as you bend over and tie down any branches that are getting taller than the rest, it grows well indoors and rewards you with above-average yields.

Closeup of a Moby Dick bud

Critical Mass CBD Autoflower

Speaking of CBD, some growers would like to maximize the amount of CBD but aren’t looking for a strain with a lot of mind-altering THC. Critical CBD Auto is a great choice and comes in auto-flowering form, which means that it will automatically grow buds and be ready to harvest about 10 weeks from germination. A nice easy strain for someone who’s just getting started.

Example of bud from a Critical CBD Auto

I’ll be adding more details about the recommended strains below soon

Frisian Dew is a great choice for outdoor growing

Importance of Strain Names

While we’re talking about breeders and strains, I want to talk about an important topic that affects all of us…

Just 50 years ago, cannabis was considered one of the most immoral and destructive drugs in the world, putting it at the top of illegal drug lists in many countries. Many people still live with this attitude.

But in some ways, things have changed.

These days, people are generally more accepting of cannabis, and laws about marijuana are slowly being changed for the better in many places around the world, especially the US.

Because of better attitudes about cannabis around the world, we get…

Fewer people are getting their lives ruined or going to prison because of a simple plant that’s more harmless than Tylenol

But good things don’t come easily. We still have a long way to go, and the cannabis legalization movement highly scrutinized. The image we create now is going to set the tone for the rest of the world.

We are the face of the cannabis community. When people think about legalizing cannabis, they’re looking at our actions. As growers, every one of us has a responsibility to represent the growing community in a positive light.

Politicians around the world are trying to decide whether removing penalties for cannabis will have a positive effect. We are at a critical turning point, and it could go either way.

We’ve come to an important fork in the road

I believe that making cannabis legal and available to adults and medical patients is incredibly important. Whether someone uses cannabis for a medical condition or just because it helps them relax, I believe that everyone should have fair and equal access to this miraculous plant.

Yet with change comes responsibility. I believe that, as growers, we have a responsibility to present a good image to the public about growing cannabis. We must earn a better reputation to prove to the world that cannabis is not only a safe source of medicine but also that cannabis is less dangerous than cigarettes or alcohol. I believe adults and medical patients deserve the freedom to use this plant responsibly.

The world is watching us, and the way we act now is going to decide whether cannabis ever gets fully legalized. That’s why I’m ashamed of some of the most popular strain names…

I am ashamed the cannabis growing community has popular strain names like…

I know a lot of these strains have great genetics; in fact, some of them are award-winners!

But do these strain names bring to mind the image of peace-loving and laid-back growers and consumers which make up the majority of the cannabis community?

I believe we must improve our public image. I have chosen to no longer grow strains that carry an offensive name. Growers, I encourage you to do the same. Strain breeders, I’m begging you! Please be mindful of the cannabis movement when naming new strains.

Don’t Let This Happen To You!

I just received this slightly alarming email, and I had to share. Don’t let this happen to you!

This is supposed to be Auto Bubble. 4 weeks in from seed. What is the deal? What is this plant?

This is NOT a marijuana plant! Unfortunately, this person got ripped off

Seeing a case like this is a huge reminder of why it’s so important to buy your seeds from a trusted seed source!

Our list only contains seed banks who have proven themselves over the years with high-quality seeds from trusted breeders, discrete shipping, and reliable delivery.

There are no perfect top lists or best of lists, but hopefully you’ll learn something new with ours. If you like this list, share it with other cannabis growers who want to be informed about cannabis breeding, seed breeders and genetics. This list does not vouch guarantee you’ll be able to locate everyone included. Many of them are accessible to the general public, however some breeders and companies are not, or their online presence is sparse.

List of the best seed breeders and genetics companies

It is recommended that you contact genetics companies and seed breeders directly to procure seeds, genetics, etc. Also, never try to purchase seeds on Facebook or Instagram.

What Are Cannabis Seed Banks?

A seed bank is a storage facility where cannabis seeds are kept to preserve their genetic quality. The seeds are safe from environmental conditions like low humidity and temperatures in the store. They are also safe from disasters like storms, floods, or explosions.

The appropriate weather conditions ensure that the seeds are in the right conditions necessary for germination when the time comes. A seed bank stores a wide variety of cannabis species and feminizes them where necessary to increase yields for buyers.

There are dozens of seeds banks in the country as people continue embracing the use of cannabis as an alternative medicine for health complications. If you are looking to buy cannabis seeds online, there are online seed banks in the US and foreign seed banks that ship quality cannabis seeds.

How To Choose The Best Cannabis Seeds?

If you are a business or an individual wishing to grow cannabis for personal or business needs, you want to produce the best and highest quality hemp seeds.

When selecting the best cannabis seeds to get value for your money, you need to consider some factors.

Keep reading to learn more.


A majority of growers plant cannabis for buds. So, to get buds, you have to be careful what gender your seeds are. For this case, ensure you select female or feminized seeds which are easy to germinate.

Male seeds are appropriate for brewing cannabis plants for long-term crops. You will also multiply your stock by growing male seeds.

If you grow regular seeds, cross-pollination is likely to occur, leading to the production of new seeds and genomes.


Genetics impacts how well suited the seeds are to a specific climate. For example, Indica seeds grow into thick short plants and yield high CBD and THC levels.

Sativa seeds flourish in warm temperatures and grow large and produce high THC content. Hybrid seeds are a crossbreed of Sativa and Indica seeds and have unique effects due to the mixing of strains.

You can also opt for auto-flowering seeds because they are non-photoperiod. They are easy to germinate even with minimal light.

The kind of seeds you choose determines the plant growth you can expect. Poor seeds genes will yield weak plants, or even the seeds may fail to germinate. Also, if you want strong and healthy plants, avoid cloned seeds

Purpose or Preference

Why are you growing cannabis? Some people grow cannabis for personal use. In this case, you need just a few plants and should buy a few hemp seeds.

If you’re growing cannabis for business, you need to be selective about the strains and the number of seeds you purchase. Different strains also serve different purposes. For example, some strains are good for pain relief, while others are best for focus.

So, when buying cannabis seeds, consider the purpose and which strain will suit your particular needs.

Availability of Growing Space

The amount of growing space is also a factor in that some strains grow tall and bushy while others are short and leafy. Some strains are suited for indoor cannabis growing, while others do well outdoors.

Plants do well when they have a good supply of air. For instance, regular seeds do well outdoors. Their growth may be uncontrollable, and they also grow tall.

Growing feminized marijuana seeds may help with limited space because you know what to expect during germination.

How to Buy Cannabis Seeds From Seed Banks: Buyer’s Guide

There are several things you need to consider when buying seeds. Some are dependent on you, while others depend on the seed bank you are buying from. When buying seeds from online cannabis seed banks, ensure you perform a thorough background check on some of the following things:

Know The Law

There are different laws and regulations in different states. Confirm if your state allows the growing of cannabis before you buy to avoid violating the law. Even in states that do not permit the growing of cannabis, purchasing or owning cannabis is not against the law.

Germination Guarantee

Germination guarantee is essential because when seeds fail to sprout, everything fails. Discounts on price, extra seeds, or free seeds are great ways of enticing customers. However, a reliable seed bank company should offer free replacement seeds if your initial seeds fail to germinate. Free seeds will help you redeem your expenses. Seed bank ompanies that do not provide germination guarantees may not provide cover if your seeds fail to grow.

Nature of Shipping

Consider seed bank companies that provide stealth shipping to their customers. Stealth shipping ensures that the seed bank takes full responsibility for anything that may happen to your order before you receive it. For example, loss or confiscating of your seeds at customs are some things that may occur to your order.

Discrete shipping gives your package a different security aspect, especially when shipping to areas where the legality of weed is hazy. Also, other times, you may want privacy for your package.

Seed Quality

The quality of the seeds you buy reflects the yield you should expect. High-quality seeds will yield huge harvests. Seeds from potent genetic strains have higher chances of sprouting than weak ones. Quality is a sign of commitment to customers and long-term success in the seed bank space.

Where to Buy Marijuana Seeds

There are several places you can buy cannabis seeds. The most appropriate seed banks-there are online stores and physical ones. However, not all seed banks sell quality seeds.

When buying cannabis seeds online, you need to identify the best online seed banks that have the qualities we discussed earlier. Ensure you do a background search from friends, website reviews, and other growers before you buy.

You also have the option of buying seeds from a medical cannabis dispensary. Dispensaries in states that allow the growing of cannabis sells cannabis seeds.

There is also the option of buying from your local cannabis seed bank. Local shops are handy when you lack time to ship. They also sell weed seeds that do well in your locality.

FAQs About Marijuana Seed Banks

Q. What is stealth shipping?

Stealth shipping is a secure way of shipping weed seeds disguised as other products. You can package them in DVDs, pencils, etc.

Stealth shipping also involves a company taking full responsibility for any issue during shipping. For example, a company may compensate you if seeds get lost during shipping.

Q. Are there any seed banks that ship to the US?

Yes. Some companies ship cannabis seeds inter-state and from other countries into the US. However, they must follow the different states’ laws on cannabis use. They ship the seeds before they can germinate as souvenirs, fish bait, or bird food. Examples of such companies are Crop King Seeds-a Canadian seed bank, and MSNL.

Q. Is it safe to purchase cannabis seeds online?

You can safely buy marijuana seeds online. Make sure you buy from a reputable seed bank to get quality seeds and avoid logistics issues.

The Bottom Line

Cannabis seeds breeders offer different types of strains. Some have invested in their cultivation for many years, while others continue with extensive research to produce distinct strains. When choosing a seed breeder, consider the type of genetics they breed-the more potent the genetic strains you select, the better the yields you will get.
