Today Amber and I documented more of our steps in the process of making a green wall. We finished priming our two molds and put mold remover spray on them. We fine-tuned our work by cutting excess primer from the edges and cutting extra slack off the mold sides. Our biggest struggle today was figuring out how to manage our mold form which is inserted into the concrete while it dries so allow for dirt space. Most of the other groups have not had success in removing inserted pieces from the final concrete piece so we new we needed to make a strategy other than relying on our [lack of] shear, brute force and strength :) So we thought about ways to wrap the insert.
Our first thought was to cover it in tin foil. This would keep it's form easily and act as a barrier between the concrete and the insert hopefully making it easy to remove after curing. Then we talked to other students and hear packing tape is supposed to work really well - we went that route.
Lastly we had known from the beginning that we would need to use the vice-clamp, or harness grip thingy to keep our mold tightly compressed and together. After fiddling and figuring out how the thing works, we clamped up our two molds and prepared them for the concrete pour.
We mixed our concrete with the recipe shown below and added quick-dry agent hoping it will be set for tomorrow's class. We have high anticipation that our molds will actually work. Fingers crossed! A plant has also been purchased in the hopes that the insert will successfully be removed.
Check out the photos and video below!

I like that your project was inspired by the movement of water. Love it!
