Top 5 Best Cannabis Seeds for Growing In UK Climate

When it comes to growing cannabis in the UK’s less-than-sunny climate, picking the right strains is like choosing a raincoat for the Great British weather—essential for success.

The strains on this list are hardy, adaptable, and downright impressive, thriving even when faced with chilly nights and drizzle-filled days. These cannabis champions don’t just survive the UK climate; they thrive in it, delivering stellar results despite the odds.

Whether you’re in the heart of London or out in the misty countryside, these strains are your go-to for a fruitful outdoor grow. Ready to meet the contenders? Let’s dive in!

1. Northern Lights Autoflower

The Northern Lights Auto 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.

2. Sexxpot

Our Sexxpot feminised seeds are a big hit in the USA and are quickly gaining popularity in the UK—and for good reason. Sexxpot is a tough, resilient strain that can handle challenging conditions with ease.

As a photoperiod strain, it requires shorter days to enter the flowering stage. To achieve a harvest by October, growers should plant these seeds in April or May.

3. OG Kush

OG Kush, with its 75% Indica genetics, is a powerhouse strain that thrives in almost any climate—from chilly regions to warmer ones.

Its robust nature makes it an excellent choice for growers in the UK, capable of delivering high-quality yields even in less-than-ideal outdoor conditions.

As a photoperiod strain, OG Kush requires planting between April and May to ensure it’s ready for harvest by October.

4. White Widow Autoflower

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 White Widow Auto can grow up to 180cm high. 

Besides, they produce high yields and aren’t dependent on the transition between summer and autumn to bloom. Moreover, White Widow autoflower is a very strong and reliable strain that is suitable for outdoor cultivation in the UK climate.

5. Critical Autoflower

Critical Auto is one of our fastest flowering Autoflowers and produces 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, making it suitable for the UK climate.
