Black Hamburg’s greenhouset dilemma, help please

I have recently bought a beautiful red cedar 14’ x 8’ greenhouse, which I am hoping to have lots lovely grapes in a year or two. The vine is just coming to the end of its first year, so in the spring I need to decide if I keep it in its large container or cut a hole in the side of the greenhouse,  so it can gets its roots into the ground. Can anybody tell me if the benefit the vine will get by being in the ground will outway cutting a hole in my greenhouse

    I do not know what the accepted method is but my grapevine which is a seedless muscat (inherited with the house) is planted inside the greenhouse in a corner, it gives good crops of grapes and I have not in 5 years watered it. I have to say the previous owner trained it diagonally across the roof which means there is not enough light for anything else to grow in the entire greenhouse! So when that greenhouse dies or I move I will not be putting a grape into a greenhouse again.

    I have a black hamburg in the corner in the soil. The greenhouse is aluminium on a concrete foundation. I assume that plenty of water finds its way in. I never water it or the fig in the other corner. My problem is keeping them under control as they grow so much.

    Knowledge is knowing that a tomato is a fruit.
    Wisdom is not putting it in a fruit salad.
