What is the biggest variety of marrow one can grow?

think its all down to how long you want to grow it for. the longer you leave it attached to the plant, the more it will grow. think the biggest i had was just under 50cm and an ideal rounders bat

I've got some 2 footers on "Long Green Bush".

Just been left to get on with it and no special attention. I'm sure with TLC they'd grow bigger.
