best outdoor autoflowering cannabis seeds uk

Do you avoid growing outdoors because you live in a cold climate? Did you know you can still achieve a fantastic yield outdoors with autos? These five strains thrive in the cold! They also produce high levels of THC, delicious aromatic terpenes, and rewarding yields that will keep your stash jars topped up to the rim.

Living in a cooler climate doesn’t mean you can’t grow weed outdoors. By growing strains designed for these conditions, you can also enjoy the blissful moments of tending to cannabis plants under the summer sun.

Sweet Skunk Automatic

Autos are much more compatible with the high humidity, short summers, and cold nights of cooler northern regions. The underpinning ruderalis genetics of these strains adapted to their harsh environments in Russia and surrounding regions, making them perfectly suited to other cold climates.

We start our list with Sweet Skunk Automatic. This indica-dominant hybrid was created by combining two popular strains: Critical Domina and Big Devil #2. Taking the best properties from both parents, this quick-growing plant races from seed to harvest in around 8 weeks. Rarely growing taller than 60–100cm, it is the perfect choice for those with limited space. But don’t be fooled into thinking this small plant won’t provide worthwhile yields. On average, you can expect up to 110g/plant.

Despite their ability to adapt, growers should still be strategic about when to sow seeds and where to put their plants. Aim to sow seeds around April and transplant them outdoors after the last frost. Try and situate them in an area of the garden that receives around 8 hours of the sun, while being sheltered from high winds.

Some varieties have even been bred to give off less smell than is usual of weed plants. Ideal if you’re growing near others.

This stunner, Purple Bud Auto, is a good option for an outdoor UK grow. She handles the cold climates well and even flourishes on a balcony, often bending under the weight of their resinous purple flowers.

Regular cannabis varieties require environmental cues in order to progress through their life-cycle. Most notably, they need a light cycle of 12h light to 12h dark in order to enter their flowering stage (where a plant start producing buds).

Due to their ruderalis genetics, auto seeds grow exceptionally quickly. The fastest can go from seed to harvest in as little as 6 weeks! Autos are often smaller in size compared to photoperiod strains, perhaps because of their speedy growth.

Therefore, ruderalis-type cannabis plants evolved to flower when they reach a certain age and regardless of light cycles. They have also learned to be very hardy and resilient to cold, mould and pests.
