Hybrid Seeds

About Hybrid Strains

The WeedSeedsExpress Hybrid Seeds collection features the best of both worlds in one strain. These seeds provide diverse flavours, effects, and growth patterns perfect for all growers, collectors, and breeders. Hybrid cannabis seeds are the fusion of two or more cannabis strains, mostly the genetics of pure Sativa and Indica. This produces a plant with traits from both parent strains and allows users to enjoy the unique blend of their effects, growth patterns, and characteristics. There are three main types of hybrid cannabis seeds: 

Balanced hybrids

Balanced hybrids have (almost) equal parts of indica and sativa genetics and offer a combination of the effects of both strains. That is the sedative effects of Indicas and the energizing qualities of Sativas. Common effects of the balanced hybrid models include happiness, uplifting, mental clarity, and physical relaxation.

Indica dominant hybrids

Indica hybrids have a higher percentage of Indica genetics – usually 60 - 80% indica. As a result, you’ll get more indicia-inducing effects such as relaxation, appetite stimulation, and anxiety, stress & pain relief. However, you’ll still experience the uplifting effects of the Sativa strain. 

Sativa dominant hybrids

As the name suggests, these hybrids have more Sativa genetics – usually 60 - 80% Sativa. They have a high THC content, so you’re more likely to get the psychoactive effect. If you want to feel energized, inspired, or highly confident, this type of hybrid strain is a great choice. You don’t have to worry about getting jittery or too stimulated. The balanced presence of the Indica genetics also helps to mellow out the overwhelming effects of pure Sativa.  

Benefits of growing hybrid strains

One of the many perks of growing hybrid cannabis strains is that you get to control the variant outcome to suit your desired outcome, whether it's energetic (sativa dominant), relaxation (Indica dominant) results, or a balance between both. In addition, the combination of cannabinoids and terpenes in the hybrids often produces a more “entourage effect.” This pair amplifies the therapeutic and medicinal benefits and works perfectly for chronic pain relief, anxiety reduction, or mood boosters. Plus, hybrids tend to inherit the best traits from their parent strains, which means higher yields, adaptability to different growing environments, and high resilience to pests and moulds. 

How to choose the right hybrid cannabis strain

Before you start growing, it's essential to choose the right cannabis strain. Consider factors such as the strain type, whether it's a skunk or gelato hybrid, and your growing conditions. 

The desired effects:

Different hybrids offer various effects, so you need to find the one that aligns with your needs. For example, Indica-dominant strains tend to induce relaxation, relieve pain, and calm the mind. Sativa dominant strains, however, are more likely to boost your mood and make you energetic.  Also, if you’re looking for a more psychoactive experience, opt for strains with high levels of THC, such as those found in Runtz or Gelato. THC, or tetrahydrocannabinol, is the primary psychoactive ingredient in Cannabis and is responsible for the “highness” you experience when consuming. Strains with high-level CBDs are often preferred for their therapeutic and medicinal use due to their non-psychoactive properties. They’re most beneficial for individuals looking for cannabis for functional relief as opposed to the THC’s intoxicating effects.  

Your experience level:

If you’re new to growing cannabis seeds, opt for low-maintenance strains like autoflowering hybrids. These strains require less control, are strong enough to thrive in any environment, and easily transition from vegetative to flowering stage without adjusting the light cycles, making them perfect for cultivating. Advanced growers and breeders can consider more demanding hybrids with stable genetics, like the photoperiod seeds. These strains require specific light cycles and nutrients to get the best yields. 

Yields

Hybrids also vary in yield. Commercial growers often breed high-yield hybrid strains like Bruce Banner, for dense flower production. Moderate-yield strains like Godfather OG or AK-48 are perfect for hobbyists or collectors who need quality yet sufficient yield. Low-yield strains, as the name suggests, are smaller but come with unique cannabinoid or terpene profiles,like C. Banana or White Widow.

Climate

When growing the seed, you also need to consider the environment. Do you plan to cultivate indoors or outdoors? What’s your climate like? If you’re planting indoors, you should probably opt for compact hybrids with Indica-dominant genes. Examples are the Critical and Gorilla Glue. Sativa-dominant hybrids with longer flowering times will be a great fit for outdoor growers. Lastly, if you live or intend to plant in colder regions with a short summer, choose autoflower hybrid seeds.  

What is the best hybrid cannabis seed?

The best hybrid cannabis seed depends on your needs and preferences. Typically, the best seeds grow under the right conditions and produce good yields. They can adapt well to different growing conditions, whether you’re planting indoors or outdoors. Beyond these, the best cannabis seeds are resilient to pests and diseases. Here are some of our best seeds based on customer’s purchase: 

Best Autoflower hybrid strains

If you’re a beginner or pro grower looking for easy-to-grow hybrid seeds with high yields, autoflower seeds are the way to go. These hybrid cannabis seeds are produced by crossing traditional Indica or Sativa strains with Cannabis Ruderalis, a subspecies known for its ability to flower automatically based on age rather than light cycles. This genetic modification allows these hybrids to retain desirable traits from both parent strains while gaining auto-flowering characteristics. 

Unlike photoperiod seeds, which require light cycles to induce flowering, autoflowers will switch from the vegetative stage to the flowering stage without changes in the light cycles. They usually have a rapid growth cycle and take only about 8 - 12 weeks from seed to harvest. They can be grown indoors or outdoors since they don’t have specific lighting needs. 

Gorilla Glue Auto

The Gorilla Glue Auto combines the best of everything you’ll love in the parent plants – the Critical Diesel Auto and Gorilla Glue #4. It offers the robust resin production and high THC of the Gorilla Glue #4 combined with the Critical Diesel Auto's rapid flowering time and resilience. This gives you a low-maintenance plant that produces dense, trichome-coated buds that thrive in different environments. Thanks to its compact size and autoflower genetics, it grows pretty fast, and you get up to 1.8 oz per square feet when grown indoors! 

Rock 'n Roll Randy, who purchased a few seeds from us, said: “I really like this strain because I'm a GG4 fan. I prefer a dank, skunky, kushy, stinky strain. This is perfect for me because it has a GG taste and smell and is very sticky. The difference is that I smoke this one all day and don't feel tired afterward.” 

AK-47 Auto

AK-47 Auto is another popular auto because of its soothing herbal flavour and relaxing high. This Indica-dominant hybrid features a generous 21% THC and 1% CBD, giving a rich blend of the potency and therapeutic benefits of both. What’s more, you get an impressive yield with a superb aroma (a mix of herbal citrus aromas and hints of sweet floral notes), which is characteristic of premium marijuana seeds. 

Fortune Seeker says: “...Super easy to grow, it grows big, sometimes too big, can take lots of stress and very good yield. I got three phenotypes: one yielded at 21.2 oz, one at 350, and the other at 250; all of them were cut down at least 2 weeks earlier, so 0 amber trichomes. The 12.3 oz pheno is super sweet in both taste and smell,  with incredible THC levels. The buds are also dense like rocks. This one I enjoy the most.”  

Best Photoperiod hybrid strains 

Feminised (photoperiod) hybrid cannabis seeds are specially designed to produce only female plants, which are responsible for producing the cannabinoid-rich flowers most growers love. They’re a result of crossbreeding two or more cannabis strains, majorly indica or sativa. Here are a few of our favorite photoperiod strains.

ACDC 

ACDC is perhaps the world’s most popular feminised hybrid seed. Because of its low THC level and high CBD (18%), it’s perfect for anyone looking to enjoy cannabis without getting “high.” The plant itself grows fast – about 14.1–17.6 oz per plant – and has a superb taste/aroma. David, who purchased this strain off our website, said: “Awesome strain. Five from six, 24 hours in the water, in the hot water cupboard, popped up and going for it within another 48 hours, amazing.”

Bubblegum 

Bubblegum is another popular strain because of its sweet, fruity, and berry-like taste. It’s a balanced variant (50% Sativa and Indica) with a high THC level of about 18%. Even when lit, it keeps a smooth, flavourful smoke without getting harsh or overpowering. It takes approximately nine weeks to grow, yielding 12.3–21.2 oz per plant!

Shari, who bought this seed from us, said, “...Last time, I had grown an autoflower strain, but I didn't like the small yields. The support team recommended I try the Bubblegum, which was awesome from growing until harvesting. I got some serious yields!! Growing indoors was pretty simple, while the plant remained small-sized. I love the sweet taste and the giggly effects.”

Best Practices for Growing Hybrid Cannabis Strains

The first and most important step in growing hybrid seeds is choosing the right strain. The best strains are authentic, genetically stable, and suit your needs. When selecting strains, you must also consider your growing conditions such as climate, space, and experience level. Auto hybrids, for instance, are more flexible and can adapt to any environment. This makes them ideal for beginner growers looking to buy cannabis seeds. Photoperiod hybrids require a more controlled setting with specific lighting, humidity, and temperature to yield, which is best for advanced growers.

Other tips are

• Understand the nutrient requirement for your hybrid strains and invest in high-quality nutrient solutions to boost their development.

• Ensure the moisture is just enough to aid growth and produce optimal yields.

• Consider implementing pruning techniques to create a more even plant structure and stimulate the growth of the bud sites.

• Be careful not to harvest too early. Follow the breeder's recommendations for your hybrid strains for the highest yield.
