The Growroom is a wooden spherical garden designed for urban areas. It has been imagined by the Denmark-based company Space10 (supported by IKEA). Instructions on how to build it are openly available on their website. All you need is a rubber hammer, 17 sheets of plywood, and a CNC milling machine. The overlapping slices of the free-standing pavilion ensure that water and light can reach vegetation on every level.
Tower Garden is a vertical, indoor and outdoor, aeroponic growing system (up to 20 vegetables, herbs, fruits and flowers on < three square feet).
