Design a greenhouse that uses desalinated sea water for watering plants

Authors:

Ines and Laura.

Area:

Environment, Technology.

Level:

High school.

Challenge:

To design prototypes of greenhouses that do not require the use of drinking water. We start with experiments based on underwater crops, with pots inside the bells submerged in a bucket of sea water, and we will study the effectiveness of these tests. We will test with different plant species, such as lentils, rocket and parsley. The final design is a model that would be located close to the coast, a covered “pool” that would be supplied with sea water and have cultivation platforms.

Teachers notes:

This project is four years old and, after each edition, the different prototypes have been presented at science fairs to receive the feedback of the judges and to continue making improvements.
