Today we started to create our bottle biome. We first cut two, 2 liter bottles at the top and bottom. On the bottom bottle, we added gravel (more to just weight it down) and water. In the top bottle we added soil, grass seeds, and alfalfa seeds. To connect the two bottles, there is a string that will provided the water to the plants. In the bottom water section we plan to add a fish (most likely a beta because it’s chances of survival are high. Since the biome is completely closed off, we don’t have to worry about evaporation and such.
