Hey friend!
At this time, outdoors, starting winter, and in your location, it will be very difficult for you: Due to the low temperatures and the light hours your plants will need.
Still, there are varieties that can withstand extreme conditions like autoflowering plants. There are Auto CBD varieties. (Low THC levels). Here’s a link with some: https://thgrow.com/en/search?search=auto+cbd
I would also recommend keeping them indoors, protected from frost, and near the balcony, where they can get as much light as possible.
These plants will be very, very small due to the few light hours, so I recommend putting in 5 to 10 seeds to get some production.
I hope I’ve been helpful, cheers!
