Yeah, at 50N and further south it can be harsh, but also very doable to grow outdoor.
When you cross 55N it all changes though, in my parts the temperature isn't the problem, but it is the moisture.
All of September are basically rainy days, and I am talking proper rainy days 20+ days in a row with 30-50mm downpour and no sun.
No autos get through that, and even the Danish and Finnish strains are pheno dependent when it comes to going to October without moulding away. This is why they are often very airy and got whispy looking buds much like the wild tropical sativas. A dense bud structure would be death around these parts.
That is my point my friend. If you start them and time them right, you can miss the rainy september entirely. An indoor start on may the 1st for 30 days will ensure that all are harvested by mid august at the latest.
