''. Accessed: 5 December 2010. The word "Groasis" is a
neologism formed as a
portmanteau of the words "grow" and "oasis".
Background
Large land areas in the world are too dry for trees to survive. Although water may be present in the ground, it is often too deep for small trees to develop a root structure to reach.
The Groasing Technology employs
biomimicry
Biomimetics or biomimicry is the emulation of the models, systems, and elements of nature for the purpose of solving complex human problems. The terms "biomimetics" and "biomimicry" are derived from grc, βίος (''bios''), life, and μίμησ ...

A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to denudation. About on ...

eroded areas, badlands and on rocks. The purpose of this technology is to replant such areas, restore the vegetation cover and make them productive with fruit trees and vegetables.
Design
The Groasis waterboxx is a
polypropylene bucket with a
lid.

Groasis Waterboxx can grow trees in any climate – even the desert
''Inhabitat'', 4 December 2010. Accessed: 5 December 2010. It has a
vertical tunnel in the middle for two plants. A wick allows water from inside the box to trickle into the ground via
capillary action. The device mimics the insulating effect bird feces provide to germinating seeds.

Groasis Waterboxx lets trees grow up in unfriendly places
'' GizMag'', 18 November 2010. Accessed: 5 December 2010. The box's lid is covered by tiny papillae, which create a
superhydrophobic surface due to the
lotus effect. The lid serves to funnel even the smallest amount of water down siphons into the box's central reservoir.
The product functions as a plant
incubator, sheltering both a newly planted
sapling and the ground around it from the heat of the sun, while providing water for the plant. The lid collects water from rain and nighttime
condensation
Condensation is the change of the state of matter from the gas phase into the liquid phase, and is the reverse of vaporization. The word most often refers to the water cycle. It can also be defined as the change in the state of water vapor to ...
, which is then stored in the bucket. The water-filled reservoir releases small amounts (around 50
ml per day) of water into the ground by a wick to water the tree and to encourage the tree to develop a root structure.
The box acts as a shield for the water in the upper ground, and this water then spreads down and out instead of being drawn to the surface and evaporated.
Both
temperature and
humidity beneath and inside the box are more stable night and day than without.
From 2003 to 2010, the development of the Groasis Waterboxx has cost $7.1 million.

Installation
Use of the box initially involves digging a hole in the ground by a human or a machine. One to three plants are planted in the hole, and a
cardboard panel is placed around the plants. In dry areas, the soil around the plants is inoculated with
mycorrhizae to release nutrients in the soil that would otherwise be chemically inaccessible to the growing plants. A wick is inserted in the bottom of the Groasis which is then lowered over the plants and filled with water. Two lids are put on, funnels inserted and a cap plugs the top lid.

Testing
The box has been testing for the 3 years at
Mohamed Premier University in
Morocco where nearly 90%'s of plants survived with the box compared to 10% without.

wineries and cold mountain regions.
Growboxx
Another version is called Growboxx. It is a recycled paper bucket and should not be removed after a year. The bucket itself becomes food for the tree
and can be ten times cheaper.
