New to growing from seed

I'll keep posting pictures as it grows.

BTW, I named him Marley.

Hi everyone, I said I would post updated pictures. I was given two seeds. Only one came up, which you have all been helping me with. Well check out the picture. The second one popped up. Now I have just one question, what do I need to do so the stems will thicken up? Or do they on their own in time? Sorry for all the questions, but you have all be very helpful. Thank you and Happy Thanksgiving.
