A pump in the \u003cstrong\u003e70-litre tank\u003c\/strong\u003e lifts nutrient solution onto the top tray, where it runs as a shallow film across the spreader mat and over bare roots before draining back to the tank for the next pass. Roots get water, feed and oxygen at the same time, so there is no over-watering, no dry-out between feeds and no build-up of salts in the root zone - the usual causes of slow growth and weak root development in pots. The only growing medium is the rockwool block each plant was started in, which keeps the system clean and leaves almost nothing to throw away at the end of a crop.
