My dad grows one every year in the greenhouse. He plants it in big pot (about 12" diameter) filled with plain compost. It's then trailed up the side of the greenhouse, tied on to the frame. You need to water them a lot, especially when the fruits have set - i think they just get fed with tomato feed ? You need to hand pollinate too. If it goes mad and sets lots of fruit, remove some, 4 or 5 on the plant is OK. Finally you will need to support the fruits as the grow, old spud bags work well - just tie the bag to somthing solid, then hang the fruit in it..
