Plant post day two

My question is if a plant would grow in sand instead of soil.

last week the plants were 1 – 1/2 inches this week my plant is 4- 4 1/2.

our plant has grown tiny pods. We don’t know what plant is growing but it seems like a bean because of the pods.

our flowers have been  pollinated and has lost its petals a lot of them have grown tall and have been growing upright some of the leaves have been turning yellow.That is normal and soon the pods are going to be big and all grown up.
