Every \u003cstrong\u003e40L combi pot\u003c\/strong\u003e feeds the roots two ways at once: a reservoir under the inner basket is aerated by a \u003cstrong\u003e4-inch airstone\u003c\/strong\u003e, as in deep water culture, while an \u003cstrong\u003eair-powered pumping column\u003c\/strong\u003e lifts solution to a \u003cstrong\u003ewatering ring\u003c\/strong\u003e round the stem, drawing extra oxygen into it as it drips. The pots are linked by Iceline pipe to the \u003cstrong\u003eGreen Man Brain Controller\u003c\/strong\u003e and a central reservoir, and each pot's sloping, raised base drains it completely back to the tank, so the whole system shares one solution - nutrient strength, pH and temperature stay even from pot to pot instead of drifting, with no build-up in any one pot. Air does the work inside the pots, which keeps electricity use and noise low.
