The majority of avid consumers usually try to stock up on bud during summer to avoid growing in cold, humid climates but unfortunately, sometimes things don’t go as expected. In some cases, cultivators are forced to grow in less-than-ideal conditions, which with most cannabis strains, tends to cause mold, wasting your time, money and ruining your whole harvest. Fortunately, autoflowering cannabis strains have come a long way and are ideal in this type of situation as they contain Ruderalis genetics which makes them more resilient to not only pests and bugs, but also to harsher climates.

So, if you’re an outdoor grower and are looking for the best autoflower cannabis seeds in the UK, look no further! Here is our top 10 seed selection for 2023. Rest assured, all of these strains will not fail to deliver high yields of top-quality bud in as little as 8 weeks without extra effort!

1. Climate In The United Kingdom

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.

“The citrus smells are very noticeable with this plant even before busting them up. At low temps you can taste some sweetness and citrus, which gives way to the richer cream or wood flavours at higher temps. I am noticing some really nice purple tones emerging in the buds this grow and alot of frost on the sugar leaves. I find that this strain hits you in the head at first but not an anxiety inducer. I also found that this strain was pretty relaxing, but not sleep inducing, and would be a good strain if you want to chill with friends, watch a movie, or gaming. Chilled but focused.”

12. In Conclusion

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.

There’s not much to do other than basic plant care and maintenance, so just keep an eye on your plants and you’ll be harvesting lots and lots of beautiful frosty buds in no time! We hope our 2023 autoflowering cannabis seeds for the UK selection will help you to prepare for your outdoor growing season in the UK and if you have grown autoflowering strains in the harsh climate before share your experience in the comment section.
