ok planted spaghetti squash from seed from old spaghetti squash. Vines grew long like they should, However on one plant a spaghetti squash grew. On others looked more like zucchini except hard exterior. So I am wondering what i have here. are they regular zucchini (on long vines?) and should be treated as a summer squash (they're big now) or should i treat them as a winter squash which will store for months, And be stringy like spaghetti squash. Can they be a hybrid? cross pollination? thanks to anyone who can help
