Interesting hydroponic unit developed by Daiwa House Industry. Leaf lettuce can be grown in 42 days from sowing seeds to harvesting. The yield is about 30 head a day, or 10,000 a year.
A drawback is the intensive use of energy, “Because agri-cube uses fluorescent lighting instead of sunlight for cultivation, the biggest expense is electricity.” Would be dope to work this with a solar unit.
