The UK climate

In this blog we present our top 5 best cannabis seeds for the UK climate so continue reading and check out UK’s best outdoor weed strains.

Note: out OG Kush seeds are none autoflowers and will therefore have to be planted between April and May to be ready for harvest in October.

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.

Those in the warmer south-west can enjoy growing longer-flowering sativa varieties. Haze Berry provides a stimulating cerebral high, berry-flavoured terpenes, and a rewarding yield. She’ll pump out up to 650g/plant after a flowering time of 9–11 weeks when grown in containers or garden beds. A cross between Super Silver Haze and DJ Short’s famous Blueberry, Haze Berry is an 80% sativa hybrid that has become quite popular for its combination of sweet berry, indica-like flavours and sativa highs.

Blue dream is a sativa strain that is mostly used for relaxation purposes. Growing it guarantees huge yields as well as sweet tasting buds after 10 to 11 weeks of cultivation under the suitable conditions.

Hollands Hope is one of the best cannabis strains for outdoor growing in the UK as it’s a very stable hybrid with predetermined outcomes. Flowering for about 8 weeks, Hollands Hope can be harvested near the end of September. Buds develop a golden-green colour when ready for harvesting and contain about 15% THC. Hollands Hope grows under 1 metre (80 – 90 cm) so it’s excellent for ‘gorilla’ grows and produces over 450+ grams of potent bud per plant.

The following are the premier cannabis seed strains as far as UK outdoor growing is concerned.

Nearly ready! Cream Caramel dripping in THC

Cream Caramel is a suitable indica strain for outdoor growing since it takes only 7 weeks to fully mature. It is also advantageous in terms of yield since its buds facilitate a great harvest both in terms of quality and quantity. Cream Caramel, named after its sweet caramel aroma, is a 90% indica cross between BlueBlack, Maple Leaf Indica, and White Rhino. Covered in a sugary coat of THC-rich resin, Cream Caramel delivers heavy, relaxing indica effects that soothe the mind and body.

Even though she can withstand harsh climates, we recommend LST techniques to provide more airflow to the buds, because they are extremely dense, water can get stuck in them and that is where mold thrives.

Because this plant grows a lot of side branches close together with dense buds, we recommend tying them down to avoid problems with mold, due to the humid climate in the UK.

This Indica dominant hybrid is easy to grow, suited for pros and beginners who will be rewarded with a prime-quality delicious resin, it’s also a great choice to grow outdoors in cold and humid climates like in the UK because of her Indica lineage.

11. Purple Punch Auto

It’s ideal to grow Indica dominant strains and preferably good genetics that are highly resilient for cold and humid climates.

If you’re thinking of starting your next growing cycle outdoors you can’t go wrong with these strains, and if you’re a medical patient, have a look at our autoflower CBD seeds for the UK. Have in mind that even if they’re resistant to disease and cold climates, they still need a minimum amount of maintenance and care so you avoid any problems. Remember that even though these strains grow well outdoors in colder and more humid climates such as in the UK, you can always build a basic greenhouse structure to protect your crop from stronger wind, rain or snow. The strains mentioned in the blog are quite resistant to colder climates but they’re living beings so if you want to get the most out of every single plant, it’s a good idea to keep them well-fed, protected from rain or snow, and keep an eye on them every day to make sure there are no signs of pests or mold attacking your garden.

Stardawg Auto is ideal for new growers and pros, she can easily forgive novice’s mistakes and can put up with training methods while easily rewarding you with up to 550gr/m2 in 63 to 70 days.

The climate in the UK is usually very humid and cold. You have to choose the strains carefully to avoid problems. By knowing the weather for the next couple of months you can plan your cultivation so you start when there’s good weather and a good amount of sunlight hours. By having (and understanding) a chart like this, you will ensure your plants grow in the best climate possible, this way you can predict when you’ll have more sunlight for your plants to develop better, an appropriate temperature so your plants develop properly and less humidity so you don’t suffer from bugs or plant disease, ultimately resulting in bigger yields, less problems, and an overall healthier plant.
