Cannabis Seeds For Outdoor Cultivation

With the outdoor season right around the corner, it’s strain picking time again. We put together a guide with the most suited strains for outdoors cultivation.

Essentially, most seeds can be grown both indoors and outdoors, however, some are more preferable than others. Ideally, you want to choose a strain that is already acclimatized to your geographical region. Obviously, if you are growing a tropical strain in a cold climate you can't expect best results. Also, if you are living in an area with short summers, don't go for an endless Sativa strain.

Picking the right strain for your climate zone

Europe is divided in three climate zones: the Northern part is cool, the central parts are temperate and the South is hot.

Strains for the cool Northern climate

In the far North, look for strains that flower in a short period of time. If your summers are extremely short, but with lots of sunlight, like in Sweden, go for an autoflowering variety. Autoflowering varieties will switch from vegetative growth to flowering regardless of the light after 2-4 weeks and will be ready for harvest in as little as 60 days after planting. For autoflowering strains, look into Royal Dwarf, Northern Force Automatic, and Critical+ Automatic. Regular plants that will do fine in colder climates are Early Skunk and Freeze Cheese.


A true dwarf plant perfectly suited for beginners. Only 50-90cm short, but yields up to 80 grams. Requires only 8-9 weeks from germinated seed to harvest and boasts a THC level of up to15%. Royal Dwarf yields rock hard buds full of resin and is super easy to grow. It has a very strong smell, very pleasant taste, and very strong high.


Developed in Russia for the colder-climate grower, the finest Pakistani indica has been crossed with an in-house secret from Crimea. Babushka Black Auto stands out from the crowd with its deep violet flowers and super sweet aroma. Its heavy resin production makes this an ideal hash plant for extraction connoisseurs. The compact size makes it perfect for those with little space indoors or out, but still want smile-inducing yields.

Indica-dominant and very hardy, these plants don’t grow much more than 50–80cm tall, and are ready to harvest after 55–60 days post-germination. The perfect plant for those that like a quick turnover and high yields from small plants. Expect 450g/m² indoors and 110g dry from a single outdoor plant. The berry sweet, hashish-flavoured smoke is an ideal painkiller or sleep aid for the insomniac.


Sticky Beast Automatic is an easy-to-grow indica-dominant hybrid that offers the best of what contemporary cannabis has to offer. The very large colas develop fast, taking on a pleasant earthy sweetness. Bubblegum imparts its distinct aromas, OG Kush adds its renowned stone, and Critical Auto contributes big, quick-maturing buds.

Sticky Beast Automatic rapidly develops and accumulates calyxes as if by magic. Ready to harvest in 8 weeks from seed, much of that time is spent flowering, with plants averaging 80cm tall. Indoors, expect an impressive 450–500g/m² and up to 170g of dried bud per plant outdoors. Easy to grow and easier to smoke, Sticky Beast Automatic can help you chill out without becoming lethargic.


Crossing of Skunk #1 and Early Pearl with good mold resistance. Early Skunk finishes flowering earlier that the original Skunk #1 without taking any of the original pungent smooth sweetness of the buds away. Produces good yields of thick buds. A vigorous plant that is well suited for beginners. Ready for harvest in October.


The fat colas of Cream Caramel - F1 Fast Version are courtesy of the expert blending of White Rhino, Maple Leaf Indica, and Blueback. The sweet caramel flavour and syrupy smoke distinguish this strain from other indica-dominant cultivars. Hard-hitting recreationally and a powerful analgesic therapeutically, Cream Caramel (F1 Fast Version) exhibits powerful indica characteristics.

This hardy, fast-flowering strain is ideal for the northern grower trying to get good weight outdoors in a short amount of time. This perfect stealth plant grows to a metre tall and provides ample buds per plant. Indoors, Cream Caramel (F1 Fast Version) tolerates the occasional mistake with nutrients, making it ideal for the beginner. Flowering time is 7 weeks, and yields of 450-600g/m² can be expected.

Top 10 Fastest Cannabis Strains For 2018

If you want to get 2018 off to a sticky green start, now is the time for action. Whether you are making a new year’s resolution to start...

Strains for the temperate climate

Strains For The Temperate Climate

With plenty of natural sunlight and long summers to let the plants soak it up, a wide variety of strains can be grown here. Countries in this region include Germany, France, the UK, Switzerland, Austria, etc. Indicas finish their cycle faster than Sativas, so you are sure to get excellent results with solid Indica strains. But even pure Sativa strains that take a little longer are possible if the plant is kept indoors for a few weeks after germination, extending the season by a few weeks. Plants well suited for the temperate climate are such strains as Critical Kush, Bubba Kush, White Widow, White Rhino and Chemdawg.


Critical Kush is an incredibly potent crossing of Critical Mass and OG Kush. It grows into a bushy plant of around 1m height and is ready for harvesting by the end of September. It delivers high yields and a THC level of up to 25%. It induces a strong stone, making it a great choice for both relaxing in the evening and medical purposes.


One of the founding creations of the contemporary cannabis oeuvre, Classic Skunk still stands out as an exceptional example of the cannabis breeder’s art. This particular strain is an unadulterated version of the original. It grows with characteristic hybrid hardiness, featuring the unique aromas that first made it a big hit. You will notice these smells in the background of many modern marijuana bouquets.

Classic Skunk is an unbeatable strain for the novice and experienced grower alike. Its forgiving nature allows beginners to make a few mistakes without too much compromise. Veteran growers will be able to push it to the limits and produce up to 500g/m² indoors. Plants can grow up to 1.5 metres tall and will respond very well to SOG or ScrOG if there are height issues.


White Widow is the primal mother of the White family and a true THC monster. She reaches a height of 150cm and has the potential to deliver up to 450 grams of large and dense buds per plant. The buds have a sweet and sour aroma with a pinch of blueberry. Medicinally valuable in case of insomnia, muscle pain, joint pain and lumbar pain.


On the cutting edge of contemporary cannabis breeding, Gelato 41 is a combination of two powerful favourites from the US West Coast. The Thin Mint Cookie version of Girl Scout Cookies, arguably the tastiest of them all, has been crossed with Sunset Sherbet. The result is a sweet, mint and citrus-flavoured strain with a stellar THC percentage of 27%.

Plants will grow to 220cm outdoors, but not much taller than 120cm indoors. This strain responds well to a number of LST techniques and produces dense clusters of buds, rather than long-running colas. Ready in 8–10 weeks, plants produce up to 800g/m² indoors and the same per plant under the sun. For those who like a hard-hitting, uplifting, and long-lasting cerebral adventure of the THC kind, Gelato 41 will become a fast favourite.


With Haze and White Widow parentage, Royal Moby was destined for greatness. It grows like a sativa, but flowers like an indica with thick bud clusters. A favourite in Spain, this strain excels outdoors, producing classic sativa trees if given the root room. Royal Moby can produce a whopping 1000g/plant.

Indoors, it can still get to 200cm. This strain ScrOGs well, but is a bit too tall for a SOG. Making the space and letting her go will result in very satisfactory returns. Flowering time is 9–10 weeks to produce 500g/m² or more. The effervescent high and pleasant body stone is worth the wait. Those who like an intense, old-school sativa buzz with an indica body load, Royal Moby is one for this summer.

Strains for the hot climate

Strains For The Hot Climate

With blazing heat and long summers, countries like Spain, Portugal, Italy and Greece are ideal to grow towering Sativas. With summer extending well into October, there's no rush for the Sativas and traditionally dry conditions won't easily lead to mold. Highly recommended strains for such a climate are Sour Diesel, Acapulco Gold, Amnesia Haze, Silver Haze and Lemon Thai Kush.


This predominantly Sativa strain is full of Diesel power. Sour Diesel is many growers’ and blowers’ favorite bud. The large, glistening buds are very aromatic, coated with resin and filled to the brim with power. The smoke has pungent, somewhat chemical, herbal and sour taste. Sour Diesel triggers an extremely long-lasting inebriation.


It could be called an old-school strain, but Durban (Durban Poison) still stands up to contemporary scrutiny. It is a heat-loving sativa from Southern Africa that has been used as the secret ingredient in many modern classics. It is a very hardy strain and is almost unkillable, whether grown indoors or outdoors. Very few weed fans have not heard of the legendary Durban Poison.

Durban Poison is a large plant, so give it plenty of room outdoors. ScrOG is recommended for indoor grows to get the most light to all the flower sites. The sweet and bitter lemon flavours precede an uplifting high that evolves into a functional trance state that lasts for hours. Flowers are ready in 60–70 days, and yields are always impressive.


The name is program. Amnesia Haze has the potential to blank-out your conscious mind. An individual plant can yield anything between 100 and 200 grams. The high THC level of 20-22% is a guarantee for a very intense cerebral effect. Amnesia Haze can grow up to a very tall plant, so choose the planting site wisely.


When discussing successfully growing cannabis in hot climates, the conversation always turns to sativa strains. Sativas don’t come much more desirable than Super Silver Haze. An impeccable heritage of weed acclimated to hot and tropical climates, it contains a touch of indica to fatten up the buds. So hardy and resilient, even the most inexperienced grower will get great results with this strain.

The Haze tradition of rushing, cerebral highs that can surprise even the most seasoned connoisseur is continued with Super Silver Haze. The yields are very attractive for a sativa-dominant strain. By late October, growers can harvest up to 550g/plant. Indoors, after a 9–10 week flowering period, expect 450–550g/m².


With a heritage outside of the typical American and European breeding lines, Acid Dough is a sativa-dominant strain that produces large purple colas on unique-looking plants. This rare blend of strains derives from the deepest African and Kush genes from the Pakistani massif. The African bloodline makes Acid Dough ideal for hotter climates.

Heavily serrated, long-fingered leaves spell sativa, but the dense internode spacing says indica. The OG influence means the flowering time is reduced to 65–70 days. The effects are as unique as the plant’s aesthetic. A pineapple-flavoured sativa mind ride with just enough indica to provide a pleasant body load, the yields from this strain are generally considered high, both indoors and out.
