This grow rack carries two ebb and flow trays measuring 110 x 63cm across two tiers. It is 136cm tall and 115 x 65cm on the floor. The 25 x 25mm aluminium frame with steel-reinforced corners is rated to 70kg per square metre. Extra tiers bolt on later, so you can keep growing upwards.
A 62-litre tank sits below the bottom tier. The pump sends nutrient water up to flood the trays, then it ebbs back when the pump cuts out. This flood and drain rhythm keeps salad leaves and microgreens fed evenly. Wheels are available on request. Trays sold separately.
