Deep Water Culture progress after one week

DWC system one week ago

I started the Deep Water Culture hydroponic system one week ago. This is how it looked back then. I quickly realized that the beans needed some kind of support since it likes to climb on things. Did some rearranging and built a ladder.

DWC system today

Beans reaching for the ceiling

Not sure what the beans are looking for at the ceiling. I'm guessing I will soon find out.
