That's way to cold my friend, cannabis growth slows to a crawl under 65F.

Might be ok with an indica strain although slow . How much daylight hours will you have?

Im guessing it is 5 degrees C so much farther south.
Near Ottawa ca today is a balmy -15C
andrea what might help is if you built a mini greeenhouse to keep them toasty

I live in the mediterranean region and in winter it very rarely goes below 5 celsius at night. I have grown outside in winter several times - and yes, you can grow but as others have stated, growth will be very slow at such a low temperature. Our winter temperatures (daytime) go from around 11-19 celsius so usually there is no problem growing outside in winter where I am. Obviously the yields are around at least a third lower if you grow during winter months when there are less sunlight hours.
I have found there are 4 things that will affect yield/potency of Autos grown outside during winter:
1. Genetics: Choose genetics that will do better in colder climes (I have had great success with hardy, Indica-dominant strains like Northern lights in winter).
2. Make sure plants get as much daylight as possible. Once an auto is planted, it's like the start pistol that begins the race - they need to get in as much Veg growth as possible before they start to flower in week 3-4. Obviously there is a lot less light in winter, so place the plants in an open, unshaded area where they will get maximum daylight hours.
3. Cold: Generally, I can keep the plants outside and uncovered during winter, but if we are experiencing a particularly cold spell, I rig up a makeshift "greenhouse" from scrap wood and PVC sheets (or any other see-through sheeting). I am no handyman but can get something up in a few minutes if necessary - basically I box the girls in with bamboo/scrap wood and transparent sheeting. When I have done this, I notice there is a difference of around 5-7 degrees celsius. So when outside night winter temperatures are say 5 celsius, the plants inside the makeshift greenhouse are in an environment that is 10-12 celsius.
4. Humidity: On the one hand, winters here can be great for the last 2-3 weeks of flower as we very often get cold, clear weather with extremely low humidity - which is ideal as the buds really frost up during those last 2-3 weeks of flowering if RH is around 40%. However, it is still the "rainy season" and we can get torrential downpours at any time. If we do get a lot of rain towards the end of the flowering period (for me more than 2 days of consecutive downpores is a lot of rain), I erect a makeshift greenhouse over the girls to protect them from getting overly damp/wet. If buds get wet the potency will be reduced and there is a high risk of nasty things killing your plant (fusarium wilt is a big problem here if the buds get wet or damp for longer than a couple of hours during the final weeks of flower during winter - I have seen it kill plants literally over night). Once the buds get really swollen (during the last week or two), keep them as dry as possible.
As long as you take care of the above issues (and you live in a reasonably temperate climate), you should be able to grow autos outside in winter.
