The AquaPro Holland Groasis Waterboxx
The Groasis Waterboxx is an irrigation-free plant incubator that is designed to make the world’s arid and semi-arid lands fertile again. It’s nothing more than an exceptionally well-designed bucket. Place the tub around a freshly planted seedling, and fill the evaporation-proof basin—just once—with four gallons of water. The Waterboxx does the rest. At night, its top cools faster than the air, collecting condensation to supplement those initial gallons. The tub drips about three tablespoons of water a day into the soil, sustaining the plant while encouraging its roots to grow deeper in search of more water. Once the plant reaches the moist soil layer, usually after a year, the farmer lifts the box off the plant and reuses it on the next sapling. Each Waterboxx is expected to last 10 years, and, for about a buck or two per tree grown, is cheap enough to use in poor nations. In tests in the Sahara, 88 percent of Waterboxx-sheltered trees survived, versus 10 percent of trees with traditional cultivation.
