Two ebb and flow trays of 204 x 63cm sit across this rack's two tiers, giving a long, narrow growing run. It stands 136cm tall on a 209 x 65cm footprint, so it suits a side wall or a gap between benches. The frame uses 25 x 25 x 1.5mm aluminium tube with steel-reinforced corners, rated to 40kg per square metre.
Each tier drains back to its own tank, so salad leaves, herbs and microgreens water themselves on a cycle. Need more height? Extra tiers bolt straight on, turning the base unit into a taller vertical growing column.
