Top 5 strains to grow in cold & damp climates

Selectively bred over many years in The Netherlands, here are the top-5 Dutch Passion photoperiod feminised cannabis seed varieties for those faced with cool, damp grow conditions such as those in e.g. Northern Europe. All these strains are naturally adapted and bred for short, typically dull/grey, grow seasons. These strains are all proven outdoor winners with thousands of repeat outdoor/guerrilla growers.
Growing cannabis in cold and damp climates
Even in borderline climates such as Northern England and Southern Scandinavia, outdoor cannabis growers can still look forward to large harvests of good quality cannabis. Key to this is choosing cannabis seed varieties that have a proven pedigree.
Breeders with several outdoor cannabis cups generally take their craft very seriously and create strains that have been professionally selectively bred to survive the often-harsh outdoor climatic demands in cool & damp climates.
Another key consideration for the serious outdoor grower is correct identification, preparation and maintenance of their outdoor grow location(s). Improving the soil (with additives, well rotted manure etc) and removal of any nearby foliage that can block sunlight to your plants will help optimise your growth potential.
Those that can grow on their own land will find it easiest to monitor and help their plants. This could include creating an overhead shelter to protect plants from the worst of the late season weather, or ensuring their plants have sufficient water in the event of a drought/heatwave. But these strains are also all tough enough to prosper in the low-maintenance conditions of guerrilla grows (grown in wild terrain e.g. hills, riverbanks, waste land etc) too.
The following grow guide was written for UK outdoor growers, who face some of the toughest outdoor conditions, and offers plenty of detailed tips for maximum success which can be applied in other countries.

Best cannabis seeds to grow in cold & humid conditions
These Dutch Passion strains have all benefitted from decades of adaptation and acclimatisation to the Dutch outdoor climate. The selective breeding process necessary for these levels of consistently resilient outdoor performance takes years to achieve.
This involves growing hundreds of candidate plants outdoors and selecting only the best performing outdoor specimens for crossing in the next generation. This process is repeated the following year, crossing only the star-performing outdoor individuals over many generations before stabilising and feminising the cannabis genetics.
Here they are, all are available in photoperiod feminised cannabis seeds.
Frisian Dew: Bullet-proof outdoor resilience
Perhaps the first strain that Dutch Passion would recommend to any grower struggling with a cold and damp climate, Frisian Dew is a seasoned outdoor champ.
She is grown extensively by guerrilla growers and is as tough & resilient as they come. Ready to harvest in late September/early October in the northern hemisphere (late March/early April in southern hemisphere).
The cannabis cup winning outdoor performance means that Frisian Dew can be relied on for maintenance-free growth and produces XXL yields. The buds enjoy a with a fresh, fruity, floral taste/aroma with powerful stress-busting effects.

Durban Poison: Killer outdoor performance and potent buds
Durban Poison is a solid repeat outdoor feminised seed choice for numerous outdoor growers around the world. The South African (mainly) sativa genetics have proven their durability over many decades. The buds produce a powerful, anti-anxiety high with a spicy, hazy taste and hints of aniseed, liquorice, lemon & cloves.
Durban Poison is easy to grow as far north as England with great outdoor weather resistance. Unusually for a leading outdoor strain, Durban Poison is also a solid choice for indoor cannabis growers seeking a premium quality harvest.

Passion #1: Top pick for potent outdoor harvests
Passion #1 is another classic outdoor strain. She is grown extensively across northern Europe though her outdoor performance isn’t perhaps quite as marked as Frisian Dew at more extreme latitudes.
Passion #1 was created from Californian 1970’s hybrid genetics and is one of the best green outdoor varieties to have been developed. She has been cultivated in The Netherlands since 1980.
She is also of the most potent outdoor strains available with her 20% THC levels on a par with quality indoor strains. Expect XL yields with a powerful euphoric ‘up’ high. The blissfully enjoyable buds slap hard with a fresh tart; spicy aroma of lemon/lime.
Frisian Duck: Stabilised webbed-leaf deformity offers unique natural stealth camouflage
Frisian Duck is a unique cannabis seed variety that grows with a completely natural (but totally weird) webbed leaf shape where the leaf fingers fuse together.
Without the iconic marijuana leaf shape, many fail to realise that Frisian Ducks plants are actually cannabis. Frisian Duck has a cult-following of greenhouse/back-garden (and front garden) growers who rely on the incognito-appearance. This allows people to grow cannabis in places where it may not otherwise be possible.
You can walk straight past a Frisian Duck plant, especially before heavy bloom sets it, and not realise it really is cannabis. The shape of the webbed/fused leaf structure looks more like a duck’s footprint than a cannabis leaf, hence the strain name.
Frisian Duck is a weather-resistant low-odour variety with medium strength THC levels, notably heavy yields and thick blooms. The main reason for so many loyal repeat growers is without doubt her one-of-a-kind naturally camouflaged appearance.
Any growers that consider these uniquely shaped leaves potentially useful for their outdoor grows may also wish to check out the autoflowering version Auto Duck (autoflower seeds).

Shaman: Heavy yielding outdoor sativa with great weather resistance
Shaman is a durable and tough outdoor sativa noted for her often outrageous growth potential and thick, heavy blooms. Around half of the plants show varying degrees of colour, from delicate pink to vivid dark purple. She is euphoric and uplifting with a fresh, fruity & spicy aroma to accompany her energetic up-high.
The sativa blooms are resistant to mould, this is a well acclimatised outdoor over-achiever thanks to the many generations of professional selective breeding applied during her development.
With several decades of proven outdoor/greenhouse performance, Shaman is a top choice for fans of potent, tasty outdoor sativa cannabis seed varieties. A best-selling member of the Dutch outdoor cannabis seed collection.

Grow the finest outdoor cannabis genetics
If you experience headaches with the early arrival of cold winter weather that makes it too risky to grow photoperiod strains then autoflower seeds are a great alternative. Even those with the shortest of summers, such as Northern Scandinavia or Alaska, will be able to find a 3–to-4-month window of decent weather which is all you need for an autoflower harvest.
The following autoflower seeds are proven outdoor performers with extra resilience for those growing in cold, damp climates. Our top-10 tips for growing autoflower seeds outdoors may also be useful reading.
• Auto Euforia - expect outstanding outdoor results from this top-rated auto skunk.
• Auto Critical Orange Punch - budget priced autoflower seeds with a potent punch.
• Auto Forbidden Cherry - colourful, extra resilient, tasty and strong.
Growing outdoors in large containers suits those growing on their own land. The plants can be moved in the event of extreme weather, though they will need regular watering/feeding. Those with the luxury of polytunnels or greenhouses will find it easiest to mitigate the effects of inclement early/late season weather and may produce the largest ‘outdoor’ harvests.
If growing in poor quality soil the best advice is to amend and improve it. Supermarket soil, fertilisers, water absorption crystals, bat guano, dolomite lime, seaweed, well-rotted manure, blood/fish/bone meal and BioTabs slow-release nutrients are all recommended.

Guerrilla growers work hard to ensure their grow locations have no easy-to-follow tracks to their carefully maintained plots and may even place protection plants (e.g. thorny brambles) around their grow location to protect it from animals and accidental human discovery. But great outdoor grow preparation is nothing without specialised outdoor cannabis seeds from a competent supplier. Choose yours wisely.
