Im curious to see how they do once the harvest is done. They are a perineal (spelling?) meaning they go dormant in the winter which is triggered by less light as well as a drop in tmperatures IDK if it would screw up their internal clock to keept em on 18/6.... just thinking out loud. You could always just throw the container in your garage over the winter untill spring and then give it a little nutes and light again and it'll come back nice. Another thing I recommend with strawberries is plucking the flowers your first year, you wont' get any strawberries but you will get some nice runners which will set you up for a bountyfull harvest the following year.
Are you looking at June bearing or everbearing?
