The UK climate

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.

With the exception of autoflowering cannabis seeds, the flowering of marijuana strains is seasonal, which means that outside growers in the UK germinate their seeds between April and May and, depending on the species, harvest between mid-September and the end of October.

Although the climate in the different regions of the UK is not very different, it’s important to realize that the climate in the UK is not the same everywhere. However, in general you can say that the UK climate is characterized by cold and wet winters with relatively cool summers. That are precisely the greatest negative factors for the growth of a cannabis plant. Both cold weather and frost can have an adverse effect on the harvest. The UK climate is therefore not ideal for outdoor growing. Nevertheless, it’s possible to realize a qualitative outdoor cultivation in the UK. Especially if you choose the right strain.

In our top 5 you will therefore find the five most robust types of weed that can produce excellent results even in the most ruthless circumstances.

2. Sexxpot

Our Sexxpot feminized cannabis seeds are a big hit in the USA, but also gain popularity in the UK. That isn’t strange at all. Sexxpot is a strong strain that can take a beating.

Do you want to limit the risk of a failed harvest and do you think the production of a normal autoflower is too low? We have some good news. Our Big White Widow auto can grow up to 180 cm high. Besides, they produce high yields and aren’t dependent on the transition between summer and autumn to bloom. Moreover, the Big WW is a very strong and reliable strain, suitable for outdoor cultivation in the UK climate.

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.

GROWING CANNABIS OUTDOORS IN THE UK IN 2021

Growing cannabis outdoors in the UK usually involves (at least) one consistent weather condition: rain! Your plants will rarely go thirsty or wilt from the heat. The UK experiences a temperate climate defined by cool, wet winters and warm, wet summers. The country rarely experiences extreme weather events, although flooding and droughts do occur from time to time. The UK sees an average of 133 days of rain and around 1,350 hours of sun per year. This fine balance of rain and sun gives plants plenty of the key resources to develop properly.

The UK features four climate segments:

South-east: This region experiences cold, biting winters along with warm, dry, and pleasant summers. Continental winds keep things relatively dry in general. South-east UK encompasses London, Brighton, Cambridge, and Norwich.

South-west: This area of the country sees mild and very rainy winters contrasted by warm and wet summers. Tropical winds from the south extend the growing season. Includes Cornwall, Devon, Bristol, and Cardiff.

North-west: The north-west experiences mild winters and cool summers. Maritime winds bring a whole load of rain all year round. This region covers Northern Ireland, northern Wales, and western Scotland.

North-east: Arctic winds from the north bring cold winters, cool summers, steady rain, and a shorter growing season. Includes Newcastle, York, Edinburgh, and Aberdeen.

IS WEED LEGAL IN THE UK?

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.

Despite the draconian nature of UK cannabis laws, things are improving. CBD products are widely available over the counter in stores, so long as they possess no more than 0.2% THC. The government also allowed doctors to start prescribing cannabis products to patients in 2018. In 2019, the NHS received the all-clear to start prescribing cannabis-based products for Lennox–Gastaut syndrome and Dravet syndrome.

The UK has a long way to go to match the more relaxed approaches of certain American states and European nations.

A GUIDE ON GROWING CANNABIS OUTDOORS IN THE UK

Below, we’ll generalise and focus on the south-east, south-west, north-east, and north-west, while touching on specific locations along the way. It’ll help if you do a little more research on your specific area just to make sure you have all the bases covered.

MARCH

Day length March 1st: 10h 57m
AVG temperature: 3–10°C

March marks the official start of spring. However, things are still pretty chilly in most of the country. But this doesn’t mean growers can’t get a head start indoors. Start germinating your seeds and placing emerging seedlings under LED lights or on a sunny windowsill.

Start weeding your beds and dressing them with high-quality compost. Layer them with straw or wood chip mulch to trap moisture and prevent weeds from returning. If you’re growing in containers, dress them with good compost, too. Start cleaning out and preparing your polytunnel or greenhouse, if you’re lucky enough to have one. Scrub down any algae from the glass panels, brush out debris, and get it ready to host your cannabis plants in the coming weeks.

Certain microclimates around the UK allow lucky growers to plant outside during March. Cultivators in the Scilly Isles, Anglesey and Dungeness usually see the last frost around late February.. Pay close attention to the forecast and decide whether the risk might pay off. Make sure to keep a backup crop growing indoors just in case.

APRIL

Day length April 1st: 12h 59m
AVG temperature: 5–13°C

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.

Only water your seedlings when the top inch of soil dries out, being careful not to overwater. Head out into the garden and keep the “bad weeds” under control. You’ll be able to sow hardy companion plants during April, such as peppermint, yarrow, coriander, and marigold. These plants will start flowering in the coming months, helping to distract pest insects and attract beneficial ones. Take a stroll around your beds, look out for weeds, and remove them by hand if you stumble across any.
