The grape fruit tree lives in a sunroom year round in the state of Mass. The new grow is near the height of my sunroom. I started the tree from seed about 1.5 years ago and it is now around 6 ft in height. How do I stop the tree from getting taller?
The only way to stop it from getting taller is to prune it, however, that will mean you will probably never get a grapefruit from the tree unless you graft some mature wood onto it. Grapefruit take a long time to mature from seed (12 yrs or longer outdoors), but mature wood from a tree that has already produced fruit will be able to bloom almost as soon as it starts to grow, especially if you graft in the fall.

Unfortunately, you choose the worst possible citrus variety to grow as a seedling tree to be cultivated in a container. Your grapefruit, will never fruit when grown indoors, due to the limited amount of space to achieve the required node count. However, now the good news. If you like Key Limes, plant a seed, and you could get fruit in 2-3 years. Or plant a seed from a mandarin, (other than a Clementine), and you will get fruit in 5 years. Both the Key Lime and mandarin will be much smaller trees. - Millet
