Growing grapes

Jay's mum surprised me with a grapevine she bought me in Asda! What a nice surprise!
They're dessert grapes. I know nothing about grapes, other than I think it needs to be planted outside, but with the greenery inside the greenhouse. Is that right? Any other tips?

Definitely not - it will shade your greenhouse completey. They are thugs.

if you can train it on a south facing wall it will grow well.

......not if you keep it cut back and confined to one side . I used to grow a grapevine and tomatoes in the same greenhouse quite successfully!  I have no chance of growing grapes outdoors in my area. The plants grow ok but not warm enough for grape formation.
