After some experimentation, we settled on a straightforward system that minimised the practical difficulty in making a structure to support growing vegetables vertically.
The system requires no soil or even a lot of space. There is no digging to do or any weeds to look out for. As it is a hydroponic system the watering is done continuously.
Due to these advantages, the system is very suitable for school children, the elderly and also people with mobility and movement challenges.
