Growing plants in space, harder than imagined. In limited load circumstances, Temple II not only have to meet the basic needs of the astronauts to survive, but also to meet the growth requirements of the plants. So, as space food, soil and water for space plants must be private custom.
According to plant experts Zhang Tao's introduction, the experiment puts vermiculite (a natural, non-toxic mineral) as soil into a rectangular box and fill it with seed. This is not a simple box which has a lot functions.Such as breathable waterproof, prevent microbial, water recycling and so on.
In addition, vermiculite and seeds accounted for only a quarter of the size of the box, the other part is reserved for growing space for plants. The box together with the storage tank, control box will be put in a sealed incubator. Temple II Bring it to the space.
Tao said that after the "Temple II" into orbit, injection command will be issued from the ground. The moment ontrol box receives the instruction, it will inject nutrient solution into soil. And the experiment was officially launched after seeds obtain nutrient solution. At the same time, the lighting systems and temperature control systems in culture box come into play to provide the environment for plant growth. Box camera will keep continuous observation on the growth process.
