The earliest published work on growing terrestrial plants without soil was the 1627 book Sylva Sylvarum or 'A Natural History' by Francis Bacon, printed a year after his death. As a result of his work, water culture became a popular research technique. In 1699, John Woodward published his water culture experiments with spearmint. He found that ...
A Veggie module weighs less than 8 kg (18 lb) and uses 90 watts. [7] It consists of three parts: a lighting system, a bellows enclosure, and a reservoir. [8] The lighting system regulates the amount and intensity of light plants receive, the bellows enclosure keeps the environment inside the unit separate from its surroundings, and the reservoir connects to plant pillows where the seeds grow.
Hydrotropism (hydro- "water"; tropism "involuntary orientation by an organism, that involves turning or curving as a positive or negative response to a stimulus") [1] is a plant's growth response in which the direction of growth is determined by a stimulus or gradient in water concentration. A common example is a plant root growing in humid air ...
The second part of the attraction takes place in The Land's "Living Laboratory", which showcases ideas about the future of agriculture. All of the plants in this section are grown through various methods of hydroponics. Plants are grown in sand, perlite, coconut coir and rockwool. There are five distinct areas of the "living laboratory", which are:
Aeroponics is the process of cultivating plants in an air or mist environment, eliminating the need for soil or an aggregate medium. The term "aeroponic" originates from the ancient Greek: aer (air) and ponos (labor, hardship, or toil).
It is a method in which a bud from the plant is joined onto the stem of another plant. [2] The plant in which the bud is implanted in eventually develops into a replica of the parent plant. The new plant can either divert its ways into forming an independent plant; however, in numerous cases it may remain attached and form various accumulations.

The book includes experiments on plant stimuli using a polygraph, a method which was pioneered by Cleve Backster. [6] [7] Parts of the book attempt to disparage science, particularly plant biology, for example by claiming science is not concerned with "what makes plants live", in order to promote its own viewpoint that plants have emotions. The ...
