astronauts have a problem with space in space. They need to save all the space they can for different things. Growing plants can take up a lot of space and are very important because they provide the astronauts with fresh food. I had this idea to make a simple yet effective way to save space for them. It is stack able so you can have them growing on top of each other and each one can grow two plants.
Step 1: How It Works
The middle square can hold water and soil in it for the plants to grow in. The outside pieces can be used to hold some kind of a small light so they plants can photosynthesizes. The grower can be stacked to make a wall of plants full of fresh food.
