Hey man my family lives in montana and i lived there for a few years,clinton,missoula.I believe its better to grow in doors.Your mind will be at rest knowing your plants are warm and not having any looky loos watching you.I would grow indica because of the heavy buds & the fact that it is a strong plant. kush photos go to indyman plants 30-40 days old and see my light set up. Four 2 light 4'ft cheap fixtures for one plant & 1 68watt clf not seen in photos in middle above plant.
