This practical activity outlines how to grow plants hydroponically in the classroom. It aims to give students an understanding of the basic growth needs of plants. It also shows how hydroponics can be utilised to provide food to humans as our population expands.

This technique can be expanded in a number of ways, for example to investigate phytoremediation.

This new protocol was written by science technician Helen Bailey, based on the techniques she has developed for her school, and funded by a SAPS Associates Award. If you have any feedback or further suggestions on the protocol, please let us know at saps@botanic.cam.ac.uk
