This two-tier grow rack holds two ebb and flow trays measuring 52 x 52cm. It stands 136cm tall and takes up just 57 x 54cm of floor. The aluminium tube frame is 25 x 25 x 1.5mm with steel-reinforced corners, rated to 70kg per square metre. Add more tiers later to grow upwards as space allows.
Under the bottom tier there is room for a 36-litre tank. A pump lifts nutrient water to the trays, then it drains back down when the pump stops. That flood and drain cycle suits microgreens, salad leaves and seedlings. Trays sold separately, and the rack can take wheels on request.
