Hi! Those sprouting seedlings are such a wonderful view! And that 'not sure' things look like pumpkins, sponge gourds or bottle gourds, lol. Their leaves look more of these veggies. I have planted them many times, and their leaves are like those in your 'not sure' picture, haha! It's just a guess, I'm not sure too, lol. Hello, to those lovely seedlings! Welcome to the outside world! 😅💚
