I have just started growing 2 grape varieties 'Mars' and 'Reliance'. My only problem is that they seem to think it's spring and it's fall and getting colder. They are potted right now since I have no permanent place to plant them at the moment. Should I leave them out to endure a winter that will likely have temp's below freezing or take them inside under grow lights and have them grow through the winter. They are growing about 0.5" to 2" daily.
