Stage Two: Vertical Farm

​

Engineer a load bearing vertical farm model to hold your soil receptacles.

Fold 4 sheets of A4 paper into a concertina.

Fold the middle area over so you can cut two holes in it. One high up and one lower.

Seperate the paper out to two sheets. Slot popsicle sticks through your slots like the image.

Then stack your soil containers on the support and insert your moisture sensor

Could you make it higher?

Could you make a paper structure that could fit everyone's soil?

​

Could you use paper circuits and program artificial light to grow some plants?
