🌿 For an Easy, Forgiving Grow
If you’re new to growing cannabis, you want a strain that won’t punish you for small mistakes. These are tough, resilient plants that are famous for being beginner-friendly.
1. Northern Lights
Northern Lights is a pure Indica that has been a favourite for decades. It’s incredibly tough, with strong natural resistance to pests and mould. With a fast flowering time and dense, resin-coated buds, this strain delivers calming, reliable results. It’s about as dependable as a plant gets.
2. Blue Dream
A legendary hybrid from California, Blue Dream is known for its balanced effects — a creative lift from its Sativa side and smooth body relaxation from its Indica heritage. Growers love it because it’s easy to manage and produces generous yields of sweet, berry-flavoured buds.
3. Granddaddy Purple
Granddaddy Purple is another classic Indica that’s perfect for beginners. It grows into a short, stocky plant that’s easy to handle in an indoor setup. Famous for its vibrant purple hues and rich grape-and-berry flavour, it rewards new growers with a beautiful, relaxing harvest.
🌾 For a Truly Massive Harvest
If your main goal is to get the biggest yield possible, these strains are for you. They’re famous for producing huge amounts of high-quality flower.
4. Moby Dick
Moby Dick is a beast of a plant. A cross between White Widow and Haze, this Sativa-dominant hybrid gets absolutely huge — especially outdoors. Expect massive yields of dense buds with a strong citrus-and-pine flavour profile.
5. Gorilla Glue
Gorilla Glue is world-famous for its heavy resin production. Its buds are so sticky they can literally jam up your scissors. That thick coating of resin means incredibly dense, weighty buds and fantastic yields at harvest time.
🍬 For Those Who Care Most About Flavour
If you’re all about unique and delicious terpene profiles, these strains are worth exploring. They’ve been bred specifically for their incredible flavours and aromas.
6. Runtz
Runtz is a modern hype strain that truly lives up to its name. A cross between Zkittlez and Gelato, Runtz is loved for its incredibly sweet, candy-like flavour. There are now many popular variations, including Purple Runtz and others.
7. Durban Poison
Durban Poison is a pure Sativa landrace from South Africa. It’s loved for its complex sweet–spicy–anise flavour and famously clear-headed, energetic high that sparks creativity and focus.
8. Amnesia Haze
A true Amsterdam legend, Amnesia Haze is a powerful Sativa-dominant strain with a bright lemon-citrus flavour and earthy undertones. The uplifting, energetic high is ideal for creativity. It’s slightly more challenging to grow due to its longer flowering time, but the payoff is exceptional for Sativa lovers.
🌿 For Growers Chasing Maximum Potency
For some people, it’s all about the highest potency available. The strains below have been specifically bred to produce extremely high levels of THC.
9. Godfather OG
Often called “The Don of all OGs”, Godfather OG is an incredibly potent Indica strain. With THC levels that have been recorded at over 30%, it delivers a very powerful, sedating high that is definitely not for beginners.
10. Permanent Marker
Permanent Marker is a newer strain that has quickly become known for its extreme potency. It’s a complex hybrid with a unique chemical and floral flavour. Its high THC content produces a strong and lasting euphoric feeling.
🌱 Feminized vs. Autoflower: What’s the Difference?
The ‘feminized vs. autoflower’ question is simpler than it sounds. First, know that all our seeds are feminized, which means they all produce female plants.
The only real difference is how they start to flower.
Photoperiod feminized seeds need you to change the light cycle to make buds. Autoflowering feminized seeds are on an internal clock and will automatically switch on their own after a few weeks, no matter the amount of light.
🌾 Where to Find Real, Quality Genetics
A strain is only as good as the stability of its parents, and only a good seed bank can guarantee that quality.
That’s why finding a source that’s passionate about preserving these legendary genetics is so important. At Sacred Seeds Australia, we make it our mission to give our customers access to genuine, high-quality cannabis seeds from the breeders who made these strains famous in the first place.
❓ FAQs
What is a ‘landrace’ strain?
A landrace is a pure, original cannabis strain that has grown in a specific part of the world for centuries. They are the ancient parents of all modern hybrid strains. Durban Poison, for example, is a pure Sativa from the port city of Durban in South Africa.
How does a strain like White Widow stay popular for so long?
Legendary strains like White Widow have stayed at the top because their genetics are incredibly stable. They consistently grow well, produce a great harvest of frosty buds, and have balanced effects that a huge range of people enjoy.
Are there ‘top strains’ for people who want high CBD instead of THC?
Absolutely. While many lists focus on high-THC for recreational use, there’s a whole category of excellent strains for growers seeking high CBD content instead.
If I want the fastest results, should I always choose an autoflowering strain?
For the absolute quickest seed-to-harvest timeline, yes. Autoflowering strains are perfect for anyone on a growing journey who wants fast results- often ready in as little as 9–10 weeks from germination.
What happens if I’m growing weed seeds and one turns out to be a male plant?
If you spot male plants (they grow pollen sacs, not buds), remove them immediately. Their pollen will cause your female plants to produce seeds instead of potent flowers. Using feminized seeds is the best way to avoid this issue.
