  i was wondering if i can plant grapes in my greenhouse. It is just a cold one..only heated by the sun. I read that some of the varieties need full sun... thanks

    The couple that own Northern Greenhouse Sales state in their catalog that they grow grapes in one of their greenhouses. Plus tomatoes etc.

    You may have problems with grapes. If you are in a cold area the heat of day cold of night in the winter will probably kill the vines. My greenhouse goes from +25C to -25C most days now (Zone 3 in central Alberta). Grapes need bees to fertilize to get a crop and bugs is one thing you do not want in your greenhouse. Better to stick to annual type of plants until you provide winter heat.
