Top 5 Best Outdoor Cannabis Strains for the UK
Growing cannabis outdoors in the UK could be very tricky due to the short summer periods and undesirable weather. Cannabis originates from much warmer climates and enjoys long periods of sun and less harsh Autumn months. That being said, it would be possible to cultivate a successful crop here in the UK when using the correct strain and utilising a few tips found in our guide to growing cannabis outside in the UK.
What makes these five strains ideal for the UK
Below we have listed the best five strains for growing outdoors in the UK. These cannabis strains were chosen due to a few different properties that their genetics contain. The most important property is fast flowering, without this an outdoor crop in the UK would easily fail due to our short summers. Another important factor is having a strong natural resistance to pests and bud rot. Whilst these issues can be identified and overcome with the help of our plant problems page, it is better to not need it in the first place! Another factor that is a little harder to get information on is knowing how the strain would cope with less sun, we can find this information by looking at the genetics used to make the strain. If they come from less sunny areas then we know that this plant can flourish in lesser conditions.
Before we continue it is important to understand that this information is purely for preserving knowledge as growing cannabis in the UK is currently illegal and can result in a criminal record, potential fines, and even time in jail.
Super Silver Haze
Super Silver Haze is a sativa dominant strain that is suitable for the UK climate as it can be grown and harvested within 10-12weeks and can produce huge yields when grown outdoors. The flowering phase takes around 8 to 9 weeks with good natural resistance to bud rot and other pests. That being said, a grower should always keep a very close eye on the crop for such things. Super Silver Haze is a classic strain that dates back to the 70’s is is very well known by smokers.

Super skunk is an indica dominant strain that can flower in just in 8-9 weeks making it an ideal candidate for a UK summer. Skunk is always incredibly popular due to the pure power and knockout smoke it produces. As an indica the buds grow fat and heavy which is great for yields but extra attention should be given towards the end of the life cycle for bud rot.

Big Skunk is an indica dominant strain, it is resistant to mold, produces high yields, and can be flowered in 8 to 9 weeks. Outside is can easily produce up to 500 grams per plant when grown to size and kept healthy – although this type of yield is very weather dependant! The anti bud rot properties come from the big bud parent that is unsurprisingly known for its colossal yields and was bred to withstand mould.

No matter what country you are in, White Widow is a fan favourite and has been around since the early 90’s. Despite the age White Widow still enjoys a lot of popularity due to the mental amounts of THC that coat her buds during flower. She is an indica dominant strain and can thrive outside in the UK taking around 8 weeks to flower. White Widow has good pest resistance when kept healthy and green but a spray of neem oil during veg always helps to keep pests away. While both parent plants are from very hot sunny places the strain is documented to perform well in less adequate conditions.
