Top 10 Outdoor Cannabis Seeds

• Early Skunk x Warlock
• Sativa dominant
• Flowering period: 50-60 days
• Available in packaging of 6 feminized and 11 regular seeds

Named after the Irish Herbalist, Biddy Early is the crossing of Early Skunk x Warlock. She is the ultimate cannabis strain for outdoor growing, especially if you live in the more northern areas of Europe – in fact, it was originally bred by Gerrit of Magus Genetics specifically for the humid and cold Dutch climate. As such, she boasts an extreme resilience to low temperatures, pests, mould, and disease. It makes her an excellent choice for novices, who want an easy to grow strain, or those living in a similar climate to the Dutch. This isn’t to say that those living in warmer climates should look away, though, as she will really flourish in the warmth. Biddy Early can grow up to 2m high, and produce some serious yields. The bud produced is multi-award winning, inducing a potent and relaxing high with its sweet, yet earthy, smoke. Biddy Early is also a fast finisher, being ready for harvest towards the end of September. Combine all of this, and you can see why she is the most popular outdoor cannabis strain here at Zativo.

• 50 - 65 days
• Indica
• Flowering period: 50 - 65 days
• Available in packaging of 10 regular seeds

As the name suggests, Guerrilla’s Gusto is all about stealthy and strong guerrilla growing. This strain of cannabis is one of the best guerrillas around, made from a combination of many Indian strains. As such, it grows with a strength and vigour required by a strain largely left to its own devices. Although actually first developed here in Spain, Guerrilla’s Gusto made a move to the Netherlands, where it was bred with other strains, and refined further to grow in cooler, less accommodating climates. Being predominantly indica, the high induced by Gusto focuses on relaxation, melting away the aches and pains of both mind and body. It is worth noting, Guerrilla’s Gusto is a regular variety of cannabis seeds, so it is possible to get male plants as well – great for those who like a bit of experimentation. In terms of flowering and yields, Guerrilla’s Gusto is able to produce a generous yield around mid-September.

• ChemDawg x Lemon Thai/Pakistani
• Indica-dominant
• Flowering period: 55 days
• Available in packaging of 1, 3, 5 and 10 feminized seeds

OG Kush by Dinafem is one of the most widely recognised cannabis strains of the modern age, and it just happens to be one that excels at outdoor growing. The result of crossing a Lemon Thai/Pakistani x Chemdawg, OG Kush has risen to notoriety as a celebrity and connoisseur favourite, especially in the US. OG Kush is extremely easy to grow, although she does need a warmer climate to really thrive. If you don’t happen to live somewhere warm, then a greenhouse is also a viable option for her. Generally speaking, she will reach heights of 3m when grown outdoors, be ready for harvest around early to mid-October, and produce yields of up to 1100g per plant. When smoked, OG Kush hits the senses with a dank, diesel, citrus flavour. This carries on into a heavily-stoned effect, resting the body in its entirety – an ideal end of day strain.

• Skunk x Northern Lights x Haze
• Sativa-dominant
• Flowering period: 8-10 weeks
• Available in packaging of 15 regular seeds

Mr. Nice is a seed bank that prides itself on its unwavering quality and old-school genetics. Super Silver Haze is a perfect example of this, showcasing the award-winning power at their disposal. Super Silver Haze won the 1997, 1998, and 1999 High Times Cannabis Cup, and still remains a firm favourite among veterans to this day. As the name suggests, she is a sativa dominant cannabis strain, inducing an extremely potent, sky-rocketing cerebral high. To be more precise, she is 25% Skunk, 25% Northern Lights, and 50% Haze. Super Silver Haze is a vigorous grower, and can be quite demanding, even when grown outdoors; as such, she is better suited to slightly more experienced growers. But the effort is worth it; Super Silver Haze can produce in excess of 550+g per plant outdoors – and we are talking 550g+ of some real top-shelf stuff. She is a tried and true classic, and the fact she remains just as popular today as she did a decade ago is a testament to her quality. There is no doubt of her deserving a place on this list as one of the best outdoor cannabis strains.

• Blueberry x OG Kush
• Indica-dominant
• Flowering period: 8-9 weeks
• Available in packaging of 3 and 6 feminized seeds

Kushberry showcases the best of US genetics, being the combination of two West Coast titans – OG Kush x Blueberry. The result is a taste explosion for the tongue and an unbridled high for the mind and body. When smoked, Kushberry produces a flavour that mixes sweet berry with the citrus tang of the diesel family. It is quite unique, and certainly one for connoisseurs to try out. The high is hailed as one of the most potent available from the DNA genetics catalogue, creating an intensely relaxed and happy feeling. Outdoors, Kushberry has a relatively fast flowering time and grows with a strong vigour. You can expect yields of roughly 500G+ per plant when grown in optimal condition, with her being ready for harvest in early October.

• Friesland ’89 Indica x Big Buddha Cheese (reversed)
• Indica-dominant
• Flowering period: 8-10 weeks
• Available in packaging of 5 and 10 feminized seeds

Freeze Cheese 89 is an old-school indica classic that has made a name for itself as a coffeeshop favourite. She is the mix of a Friesland ’89 Indica x Big Buddha Cheese (reversed), combining the best of both into a frosty, dank and elegant plant able to hold its weight against younger modern strains even to this day. As you would expect from a classic indica variety, the effect induced is a hard hitting, heavy stone. The flavour profile combines fresh lemon and pine with more pungent skunky and cheese undertones. It is quite a treat, and one of the reasons she is such a bestseller with our customers. Freeze Cheese ’89 isn’t just about old-school flavours and highs, though. Thanks to the expertise behind her breeding, she is easy to grow and offers a good deal of resilience to mould and pests. As such, she is just as suited to the novice taking their first steps into outdoor growing as she is to the veteran or connoisseur looking for a top-shelf strain for their stash. As she grows, she becomes absolutely coated in frosty resin, making her exceptional for hash production, as well – Big Buddha has even lovingly nicknamed her “the frostmaster.” When grown outdoors, Freeze Cheese ’89 is usually ready by mid-October and offers above-average yields.

• Blueberry x Northern Lights XL
• Indica-dominant
• Flowering period: 60 days
• Available in packaging of 3, 5 and 10 feminized seeds

Blueberry is a legend of the cannabis world, having been on the scene since the late 70’s. Ever since, she has been involved in the creation of countless other strains, all using the best of her genetics as a base. Blueberry by Zambeza is Seeds just one example of this, combining the original Blueberry with Northern Lights XL. The result is a hybrid that stays true to its origins, but adds in a little of the resilience needed to flourish in the colder climate of Europe. When smoked, Blueberry produces a sweet fruity flavour that will have you coming back for more. The high is a potent, yet relaxing body stone, easing you into bliss. This all combines into a well-rounded outdoor cannabis strain, but the added resilience, in particular, makes her popular with European growers – hence her place on our best outdoor strains list. Blueberry is usually ready for harvest early October, and can produce yields of 400g+ per plant.

• Trainwreck x Sour Diesel x Thai
• Sativa-dominant
• Flowering period: 55-60 days
• Available in packaging of 3, 5 and 10 feminized seeds

Made from the mix of the legendary Trainwreck x Sour Diesel x Thai, Casey Jones is a relatively new strain that has quickly made a name for herself as one of the best outdoor cannabis strains around – winning multiple awards. When grown outdoors, Casey Jones is not afraid to make a statement, growing large and imposing – something those who consider stealth to be an issue should take into account, as Casey won’t make an effort to hide. The plus side is that you can potentially end up gigantic bud as big as your forearm, which is sure to put a smile on your face.
