Mystery Squash...

I have started my garden!!! The first plants were peppers, followed by onions... The onions are growing alright. I  took too long to move them from the water force start to soil... But they are slowly recovering. The soil I used was, compost. It was too cold to dig some from outside. This morning I noticed I had more than just onions growing...

Now I will have to wait until more mature leaves grow and possible a fruit before we know if it is a pumpkin or a zucchini...
