The Groasis Waterboxx was invented by Pieter Hoff, a Dutch tulip exporter who retired to find a way to help green the deserts. After copying the best concepts nature had to offer (from the lessons of bird droppings to the Lotus Effect to capillary water), Mr. Hoff had developed the Groasis Waterboxx, which is initially filled up with 4 gallons of water, with another 10 poured into the soil where the plant is to be planted. The tree is planted in the central opening of the Waterboxx, and its roots grow straight down to access the soil water column released by the Waterboxx. The Waterboxx collects dew whenever present and is completely refilled by just 4 inches of rainwater. The whole process of the Waterboxx is explained below:
The Groasis Waterboxx has been tested in several deserts around the world. Its first large scale test was in the great Sahara Desert in Morocco. Below you see the initial planting of Tamarix (salt ceder) trees in a land of nothing but dry sand. This planting took place in October 2014.

These trees thrived. Using the Waterboxx, tree plantings in Morocco had a 88% first year survival rate, compared to 11% with the non-Waterboxx trees, which were watered weekly. When two trees are planted per Waterboxx (as intended) the chance that one of them survives is 99%. The Waterboxx was left in place until the trees outgrew them, and the results are seen below.

Tree plantings in the desert of Ecuador were even more impressive. Below you see over one year's growth of a Beechwood tree planted with the Waterboxx.
