First attempts
The very first experiments we did with the tobacco seeds was extremely basic. We stuck tobacco seeds in: The seeds went in an Ependorff microcentrifuge tube with about 100 μL of the respective waters with 6 seeds each. The results of this experiment were surprising. I have left these seeds in their tubes for over a month now.
 * 18.2 MΩ-cm H2O
 * Tap water
 * Deuterium depleted water
 * 100% D2O

Second attempt
The next step we took was to design and implement a camera rig so that we could observe multiple assays at once.

I should note that the seeds that we are observing in this setup have not sprouted yet. I have no clue as to why this is the case but I suspect it is the nail polish.

Third attempt
Because I think the reason why I have not observed sprouting yet is due to the nail polish, I have made a new design that attempts to keep the nail polish away from the water the seeds are in. I have done this with a different nail polish, a clear one, and some beeswax. I'm hopeful that this will work. Once the nail polish dries, I will take an image of it and how it here.
