After planting or transplanting, no additional labor is required until harvesting. Electricity and pumps are not needed, so the additional production costs and complexities associated with aeration and circulation in many conventional hydroponic systems are totally avoided by this method. This system is extremely efficient with water use. Water use efficiencies of less than 20 liters per kg of lettuce are common, and an efficiency as low as 11 liters per kg of lettuce has been recorded. Growers typically aim for 150 to 250 gram heads with this growing method, and the nutrient solution consumption range is typically in the range of 3 to 6 liters per plant.
