Are you looking for big yields this year? Then you’re in the right place! The 10 strains below will keep your stash jars filled for weeks following harvest. Whether you prefer to grow indoors in controlled conditions or outside under the sun, these varieties will knock it out of the park and serve up plenty of fat sticky buds. Our skilled breeders focused on yield while creating these cultivars, but they also boast moreish tastes and a wide range of psychoactive experiences, from uplifting and euphoric to relaxing and stoning. Check out the biggest yielding strains of 2025 below. 

TOP PRODUCTIVE FEMINIZED CANNABIS STRAINS

1. ROYAL MOBY

Royal Moby is a Spanish classic. This is a remarkable Sativa that will grow to a height of 2 meters indoors. Outdoors she can reach 3 meters in optimal conditions. She will grow long, stretchy branches with an abundance of fat buds.

Due to her respectable size, Royal Moby will yield up to 2.6 oz per plant or 21.2 oz per square metre under a 600W light. If you want to grow her to her full potential, it’s best when you grow her outside in a sunny climate like in Spain or Italy. Don’t be surprised because this is where she may reward you with a whopping 35.3 oz per plant!

You won’t see much about her Indica side when you grow Royal Moby, except when it comes to one of her best qualities: Her rather short flowering time of only 9-10 weeks. This makes her an excellent choice for cash croppers who want a first-grade Sativa with impressive yields but minus the long wait.

Royal Moby has one of the highest THC content among cannabis strains, which ensures an out-of-this-world high. With those fine qualities and her massive yields, Royal Moby deserves a spot in our top 10 production list!

2. PURPLE QUEEN

Sitting atop the indica throne, Purple Queen rules her kingdom with a calm yet powerful fist. With a genetic background of Hindu Kush and Purple Afghani, what else would you expect? This strain clocks in at 22% THC, meaning she can bring you down quickly. Since she’s indica-dominant, though, the soothing, relaxed sensation she brings, will make sure it's a smooth ride to the couch. Purple Queen has a tasty citrus flavor to satisfy those with a sweet tooth, while offering a pine aroma for the nature lovers out there.

What's more, you'll have just as good of a time growing Purple Queen as you will smoking her. This strain is able to grow both indoors and outdoors, and can handle temperate and warmer climates alike. Strains of this tier often require extensive maintenance and time. With Purple Queen, though, you'll be ready to harvest after just 8–9 weeks on a 12/12 light/dark cycle. For those growing outdoors, she’ll be ready by mid-September, early October. Compact yet branchy, she doesn’t usually get taller than 1 meter. You can expect a yield of around 15.9 – 17.6 oz/m² indoors, and 22.9 – 24.7 oz per plant outdoors.

3. GREEN GELATO

If you put some actual Thin Mint cookies into a bowl of sherbet, we're sure it would become a delicious dessert. It only makes sense that the combo of mother strains Thin Mint Cookies and Sunset Sherbet created one of the tastiest strains on the market, Green Gelato. Hailing from the San Francisco Bay Area, this tantalizing hybrid strain offers smokers a fruity flavor, while gracing the room with the aroma of freshly baked cookies. You might want to stock up on some actual cookies too, since these 25% THC nugs will surely induce the munchies. Green Gelato looks as good as she hits, with the dense nugs showing off vibrant hues of purple and orange.

Thankfully, you won't have to wait too long to enjoy this strain, since she’s ready for harvest after a mere 8–9 weeks of flowering indoors. Pruning and training the plant will work wonders for the yield. The ScrOG method, along with topping, mainlining, fimming, and LST are all highly recommended as well. Be sure to also note that, rather than long-running colas, the flowers of this plant form tight clusters that are small to medium in size. Lastly, if you want those purple hues to shine, cool down the growing area at night towards the end of the bloom phase.

4. SHOGUN

Much like the shoguns of old, our Shogun is a focused, determined and powerful warrior. With a genetic background featuring Amnesia Haze and Gorilla #4, she brings together potency, flavor and yields into a complete all-rounder. The high Shogun supplies is true to the namesake. Expect focus and unbridled strength. Weighing in with 25% THC, she can easily overwhelm novices, but if you hit the sweet spot, she will put you in the zone, ready to conquer all the day's events. If you go too far, you can expect her balanced indica side to take hold and take you into physical relaxation as your mind continues to be uplifted.

Shogun is easy to grow, making her suitable for novices growers as well as veterans. She can thrive indoors and outdoors but also know she is a hungry plant, so you will need to make sure she is well fed to maximise results. Under the right conditions, you can yield up to as much as 21.2 oz/m² indoors after 9–11 weeks of flowering and 750/plant outdoors.

TOP PRODUCTIVE AUTOFLOWERING CANNABIS STRAINS

5. ROYAL CHEESE AUTO

Royal Cheese Auto is one of the most popular autoflowering strains and not without several good reasons. Cannabis enthusiasts love the excellent and very strong cheesy flavor of Royal Cheese Auto, which makes her stand out among other strains. She is very easy to grow as well and delights with a short life cycle of only 10 weeks from seed to harvest, in which she’ll spend 7 weeks in bloom.

Royal Cheese Auto will stay a manageable 39 inches although some plants may grow taller and others a little shorter. She will reward with respectable yields up to 5.6 oz per plant on average and 7.4 oz in optimal conditions

With her great cheesy taste and a strong effect that is very relaxing, Royal Cheese Auto is an excellent choice for anyone who wants an easy growing autoflower that won’t disappoint.

6. WHITE WIDOW AUTO

Like her big regular sister, White Widow Auto grows wide and dark green leaves, that are coated with tons of glistening resin. Growers will love, that she will do this in a short 75 days from seed to harvest.

White Widow Auto may grow to an unassuming height of around 19.5 inches with some plants reaching 39 inches. This makes White Widow Auto an ideal strain if you want a plant to grow where space is limited or for stealth grows. Where she shines, despite her size, is with some good yields for an autoflower. You can expect 6.7 to 8.5 oz per plant.

When smoked, you will notice a pleasant sweet and sour taste with nicely complementing citrus notes on top of it. Her effect is similar to the original White Widow but with a slightly more physical stone.

7. NORTHERN LIGHT AUTO

This Indica-dominant strain has become extremely popular since her first appearance back in the 1970s. Like other classic famous strains, breeders have improved Northern Lights over time. This variety is a great example where the best of old genetics is kept and blended with new qualities.

Northern Light Automatic is one of those strains that you can grow almost everywhere. She will do fine in almost any climate, and she won’t have troubles grown indoors or outdoors. What makes Northern Light Automatic unique is that she will start flowering very quickly. Despite the easiness to grow her, Northern Light Automatic is one of the best yielding autoflowering strains that is available today, and she’ll do it in a short 9-10 weeks.

She will grow to about 3 - 3.9 feet, somewhat taller than many other autoflowers, but this is one reason why she excels when it comes to yields. In optimal conditions outdoors she can produce up to 7.1 oz, although most growers will likely see around 3.2 oz per plant when they grow her indoors.

Northern Light Automatic delights with a nice sweet taste and a high that is equally pleasant and very relaxing.

8. NORTH THUNDERFUCK AUTOMATIC

North Thunderfuck Automatic stems from a cross between the original North Thunderfuck and a cannabis ruderalis male. The addition of ruderalis genetics infused this USA Premium strain with autoflowering properties that make her easy to grow and fast to yield. Speed and ease aside, this hard-hitting auto stands as one of the most potent available and disrupts the narrative that autos lack THC.
So, what can you expect from North Thunderfuck Automatic in the grow room or garden? Let’s start off indoors. This strain will grow to an easily manageable height of 3 – 4.6 feet (you can keep her on the shorter side using techniques such as LST). After only 10–12 weeks following germination, you’ll harvest up to 19.4 oz/m². Outdoors, this productive lady peaks at a height of 58.5 inches, provides up to 4.9 oz and will reach harvest time in an equally rapid window of time. You can make life easy by sowing companion plants in close proximity to North Thunderfuck Automatic to bring in beneficial insects to defend your crop.
Following harvest, you’ll get to treat your cannabinoid receptors and taste buds with a delightful experience. After hitting a vape, joint, or bong packed with these flowers, you’ll find notes of earthiness, lime, and skunk roll over your tongue. Shortly after this sensory bliss, North Thunderfuck Automatic’s THC content of 21% will make itself known. Her uplifting effect will elevate your mind and put you in a creative mood, while also relaxing the body and melting your muscles.

TOP PRODUCTIVE CBD CANNABIS STRAINS

9. MEDICAL MASS

Medical Mass is a perfect cannabis strain for those medical cannabis users who want a manageable and easy-to-grow plant. This cross between the popular Royal Medic and Royal Highness ensures a potent strain that’s perfect for treating chronic pains and other conditions without the psychoactive effects of THC.

When you grow her, you can expect 500-19.4 oz per square meter indoors. Outdoors, in ideal conditions, she can yield about 500-19.4 oz per plant. Her rather short flowering time of only 7-8 weeks is another plus for the grower. No matter how and where you grow Medical Mass, her growing vigour will ensure some excellent yields.

Medical Mass delights with a complex and very rich flavor that combines sweet notes with flowery tones. She’s a good example for that growing a top grade CBD strain doesn’t mean having to accept any compromises.

10. PAINKILLER XL

This special strain, as her name suggests, was bred to build on the healing aspect of cannabis. Painkiller XL is what's known as a 1:1 strain, meaning she has an equal percentage of THC and CBD (9% in this case).

The bloom period lasts around eight weeks with this plant, and yields are around 500–19.4 oz/m², whether you grow indoors or out. The difference, however, comes with her height. The plant will hit somewhere around 31.2 inches indoors, while it can stretch up to 52.7 inches outdoors. If you're growing outdoors, you should expect to collect your harvest around the end of September.

SECTION 5 – COOKIES

Cookies are small information files that notify your computer of previous interactions with our website. These cookies are stored on your hard drive, not on our website. Essentially, when you use our website, your computer displays its cookies to us, informing our site that you have visited before. This allows our website to function more quickly and remember aspects related to your previous visits (such as your username), making your experience more convenient. At Royal Queen Seeds, we use two types of cookies: functional and analytical.

5.2 Analytical Cookies

Analytical cookies are used for research and market analysis. The data collected with these analytical cookies is anonymous, making it unusable for third parties. The use of these cookies does not require prior authorization.

SECTION 5 – THIRD-PARTY SERVICES

Third-party services are required to conduct transactions and provide our services. In general, the third-party providers we use will only collect, use and disclose your information to the extent necessary to enable them to perform the services they provide to us.

However, certain third-party service providers, such as payment gateways and other payment transaction processors, have their own privacy policies regarding the information we must provide to them for your transactions.

We encourage you to read the privacy policies of these providers so that you can understand how these providers will handle your personal information.

In particular, certain suppliers may be located or have facilities located in a different jurisdiction than yours or ours. Therefore, if you choose to proceed with a transaction involving the services of a third party, your information may be subject to the laws of the jurisdiction in which that service provider or its facilities are located.

Once you leave our website or are redirected to a third-party website or application, you are no longer governed by this Privacy Policy or the Terms of Service of our website.

Web analytics service (anonymous data)

On this website we have integrated an element of a web analytics service (with anonymisation functionality). Web analytics can be defined as the gathering, processing and analysis of data about the behaviour of visitors to websites. An analytics service collects, among other things, data about which website a person came from (the so-called referrer), which sub-pages they visited or how often and for how long they visited a sub-page. Web analytics is mainly used for website optimisation and for a cost–benefit analysis of internet advertising.

Courier service

To complete deliveries we use a courier service. This courier service carries out the delivery between our company and the consumer's home. To complete these logistics, the company requires access to the consumer's name and address information.

Mailing service

Royal Queen Seeds uses a third-party mail service provider to send its newsletter. This provider has access to limited account information related to opt-in consent (e.g. email address).

Marketing services

Royal Queen Seeds has the support of a company that specialises in marketing and communication activities. Their access to personal information is very limited and mostly anonymous.

Payment services

At Royal Queen Seeds we use external payment services to handle our transactions (e.g. credit card payments).

SECTION 6 – SECURITY

To protect your personal information, we take reasonable precautions and follow industry standard best practices to ensure that it is not inappropriately lost, misused, accessed, disclosed, altered or destroyed.

If you provide us with your credit card information, the information is encrypted using secure socket layer technology (SSL) and stored using AES-256 encryption. Although no method of transmission over the internet or electronic storage is 100% secure, we follow all PCI-DSS requirements and implement additional industry standards that are commonly accepted. Information related to the account is protected with a hashing method. This method transforms the information into a generated hash. As a result, confidential information is protected and invisible, even to us. In addition, our databases are exceptionally protected against unauthorised access. For example, access to the database is only possible and permitted via approved IP addresses (e.g. from Royal Queen Seeds headquarters). Other attempts and addresses are rejected at all times.

Furthermore, data is anonymised as much as possible, so it cannot be directly linked to a specific consumer. With this data, however, we may be able to carry out market research and analysis. In addition, the third parties concerned (e.g. mailing service) are examined prior to our collaboration, comply with the GDPR from the EU and receive a processing agreement. Within Royal Queen Seeds, employees are assigned different access permissions. Specific permission provides access only to information that is strictly required to perform a task. Digital security measures are subject to change and must meet high requirements to ensure the safety of online customers. That is why, at Royal Queen Seeds, we appoint a security officer. Regular verification and improvement of security measures (where necessary) are part of the role.

SECTION 7 – CHANGES TO THIS PRIVACY POLICY

We reserve the right to modify this Privacy Policy at any time, so please check back regularly. Changes and clarifications will be effective immediately upon being published on the Website. If we make substantial changes to this policy, we will notify you here that it has been updated so you will know what information we collect, how we use it and under what circumstances, if any, we use and/or disclose it.

SECTION 8 – YOU HAVE THE RIGHT TO:
