Note: out OG Kush seeds are non-autoflowers and will therefore have to be planted between April and May to be ready for harvest in October.

Before we share our top 5, it’s important to understand the climate of the UK when it comes to growing cannabis outdoors. In this way you understand the growing conditions better and you start your breeding well prepared.
4. Big White Widow autoflower
Critical autoflowering is one of our fastest flowering autoflowers and produces a high quality weed production. With its strong genetic background (50% Indica, 30% Sativa and 20% ruderalis genes), Critical is a very strong autoflower that will develop well in harsh conditions. In short: suitable for the UK climate.
The Northern Lights autoflower is probably one of the most robust species in our range. Instead of flowering during the transition from summer to autumn it flowers based on age. Because this species is strong and also less dependent on the weather, this species is suitable for outdoor growing in the UK.

Perfect for growing outdoors, the strain needs about 7–8 weeks to mature its flowers. If all goes well, you can bring in 500g/plant by mid-September.
With Fat Banana, the breeders at RQS managed to hybridise the biggest and fattest Banana OG specimens. This Kush strain will seduce you with fruity flavours, and it may lay you flat on your couch with its incredibly potent smoke.
Critical Kush features some of the cerebral and rather sativa-like effects of OG Kush in addition to the powerful couch-lock stone of Critical—a classic scenario of “buy one high, get one free”. Growers looking for a sturdy, potent, and profit-yielding strain for the outdoors won’t make a bad decision with Critical Kush. The rewards you’ll receive in late September are huge: outdoor yields of up to 550g/plant, a long-lasting and intense effect, and a final product with an average THC level of 20%.
Besides its short flowering period and amazing flavour, Honey Cream convinces with a solid indica background composed of BlueBlack (Blueberry x Black Domina), Maple Leaf Indica (100% Afghan indica), and White Rhino. These three strains give Honey Cream FF an indica-dominant genetic profile, but there’s also a decent amount of sativa potency from White Widow, the predecessor of White Rhino. When things go well, plants reach outdoor heights of 180–250cm and yield up to 675g/plant.
Next up is Speedy Chile. This girl combines Early Skunk genetics with several Chile indica landraces, although a third generation autoflowering plant is partly responsible for its very short flowering time of just 6 weeks (42 days!).
When selecting a cannabis strain to grow outdoors, speed shouldn’t be the only concern. It’s also important for plants to be productive, to have a good aroma, and to induce a pleasant effect once smoked.
For outdoor cultivators and novice growers, choosing Speedy Chile Fast Flowering is a wise decision. You can fill your bags with buds in early September, which leaves no room for uncertainty regarding climate or mould issues. And the buds you gather will be excellent in their own right, producing sumptuous flavours of fruit and pine alongside a THC content of 16%.
April brings a significant improvement in weather and sunlight. Bluebells, wild garlic, and other aromatic spring flowers lead the charge of emerging plant life. Although April brings a nice, warm heat, frost still poses a significant risk. Growers in most regions will need to keep their plants indoors under lights and on windowsills for a couple more weeks to be safe. However, cultivators with greenhouses or polytunnels will be able to safely move their plants to these structures during April.

Unfortunately, the United Kingdom is lagging behind more progressive European nations when it comes to cannabis legislation. The government categorises cannabis as a class B substance, meaning mere possession can lead to a maximum 5-year prison sentence, an unlimited fine, or both. Growing and supplying cannabis can lead to the more extreme punishments of up to 14 years in prison, an unlimited fine, or both.
Growing outdoors comes with a unique set of challenges per location. Everything needs to be considered, from local pest species to the best strain for the job. Simply follow the growing guide below to boost your chances of a successful outdoor harvest in the UK.
The UK has a long way to go to match the more relaxed approaches of certain American states and European nations.
