Watercress-o, watercress-o,
Crying, “tuppence a basket, watercress-o!”

Kamil has built this mini combined basic hydroponics and pond water cleaning system – with a small £12 solar pump, pumping water into a tray with pebbles and watercress.  The tray is slightly tilted towards the pond.

Results: the water in the pond clear after a week. Watercress: harvest once every two weeks.

Apparently, a few trays could be built up over each other on a scaffolding… to increase the growing space and cleaning ability.

(As your humble web-editor, I rarely express an opinion here – but in this case I really do have to say what a brilliant idea this is…)
