No soil? No problem. H2Grow can cultivate crops practically anywhere
"A lush, green mat of fresh animal fodder is an unlikely sight in the harsh Sahara Desert, but a project from the United Nations World Food Programme (WFP) is helping crops flourish in unexpected places. Using purpose-built hydroponic systems, Sahrawi refugees in Western Algeria have been able to grow barley grass to feed their livestock, in turn increasing milk production and meat quality. By selling surplus fodder, the refugees have been able to earn additional income and buy goods once beyond their means. Some 150 units have been installed in the past few years, producing nearly 4,500 pounds of fodder per day."
