Which Strain is Best for Growing Cannabis Outdoors in the UK

It doesn't matter how resistant to mould your strain is, if the temperatures drop below 15°c, and the humidity is high, you can easily find mould on your buds. The strains listed below, have all been grown successfully outdoors in the UK.
Remember, be safe when you're growing! Follow the three rules, if you think someone is going to find out about your plant, then don't do it! Cannabis cultivation is illegal, dont tell, don't sell, cover the smell.
It isn't going to be possible to cover the smell outdoors, so if you're to close to people, either neighbours or passers by on paths, do not grow outdoors! Security is number one priority.

Growing Autoflowering Cannabis Strains Outdoors in the UK
Photoperiod cannabis plants can take from mid april, until November, to complete their grow cycle. This can be far too long for some growers, and of course if you're growing illegally, the longer the grow takes, the more risk you are at.
Auto flowering cannabis plants can start from germination, and finish at harvest in as little as 12 weeks. This makes them ideal for outdoor growing, as you can fit the grow into the best part of the season.
You can find the autoflower inversions of all of the strains listed above. They have the same characteristics as the photoperiod versions, but they will come to harvest sooner. Growing an auto, instead of a photoperiod plant, will also remove the problem of light leaks during night hours.

In the uk outdoors it’s autoflowers all the way for me, size is more manageable and no problem waiting for it to finish too late in the autumn, personally I’d build or buy something that will keep the rain off them.
Couldn't agree more mate. Autos will be done way before the cold weather sets in. And you can never be sure on a good summer in the UK. Probably only get about 2 weeks of decent grow time lol

Excellent read macky, love my Dutch passion it’s my personal favourite 🙂
This is going to inspire me to do an outdoor. I've found 2 excellent hillside locations that are South facing, both areas are heavily covered in gorse and nettles. And I've read from a reputable source that growing cannabis in the same soil used by nettles gives cannabis a stronger taste and smell due to increased terpene production.
I was planning on doing pots instead of in the ground but I'm driven to cutting the bottom off the pots and planting them in the ground. And I was also planning on building a small greenhouse with green plastic and a few lengths of 2x2. To shelter the plants from the elements including pests. Because both locations are full of wildlife. Hares, badgers, deer, foxes. And possible black cats. I even have to arm myself with a big stick incase I get attacked by one.
However the guides are great reading and I hate reading. Without it though I wouldn't have discovered auto frisian dew. And I'm going to be doing that
