Outdoor flowering problem

hey I have a problem with flowering time outdoors. I recently purchased 3 sour diesel teens. They are a nice size with many bud sites but ive decided i want to veg them just a little more to get that extra amount of growth. I then wanted to place them outside to begin flowering. The only problem is that where I live, someone told me that june and july are the only times that you can veg a plant. The rest of the time is flowering. So, will my sour diesels not finish before june/july and start to reveg? How many months do sour d's take to flower outdoors? If anyone knows or has suggestions please let me know!

Diesel is a 12 week strain. If you are not harvested by mid may you will need to black out or light deprive your plants.

So many diesels going around. Mine took a little over 9 weeks outdoors. Go for Indicas or Hybrids if flower time is a issue. Lots of good strains flowering in only 50-60 days.
