A \u003cstrong\u003efloat valve\u003c\/strong\u003e sits in its own housing at the front of the tray and holds a shallow level of nutrient solution under the pot, opening to top it up from your reservoir as the plant drinks and closing again when the level is restored. There is no pump, no timer and no power involved, and because the valve only lets in what the plant has used, the root zone never sits waterlogged and never dries out between visits – the two things that do most damage to \u003cstrong\u003eroot development\u003c\/strong\u003e and \u003cstrong\u003enutrient uptake\u003c\/strong\u003e when plants are watered by hand.\u003c\/p\u003e\u003cp\u003eEach module runs from one feed line, so you can use a single MegaPot in a small tent or link as many as your grow room takes, all supplied from the same tank.
