Help with planning of outdoor growth

Hi, i am wondering how to plan my grow now that i live in sweden. My annual plan was to let them veg for about 1,5 months and later on move them out in 20 l pots so they can thrive in the natural sun and warmth.
I am going to veg them under 17/7- time schedual whith MH lamps either from the middle of marsch (or the beggining) untill the beginning of may. Thats when the weather starts getting warmer in sweden (may) and there is 17 hours of light outside.

Now my problem is that the days will get longer after may and start getting shorter after the end of june. The days become 12-12 around october when its to cold for them to be outside. How can i do so that they will bloom before it is to cold?

You can go outside with them anytime after the days are 14 hours long as far as the danger of early flower is concerned. Just slowly scale back your hours to match what the natural light will be when you plan on putting them out. Not sure how the cold stacks up with that date.

They will start to flower before the Fall Equinox {12/12}. About 13 1/2 hour days and 14 1/2 nights is when most strains will start to flower. You can get a short season strain so they start and finish earlier.
