Three months prior to conducting the experiment, they maintained an average precipitation, air temperature, and overall subtropical environment. [6] Using 12 units, they filled them with aquifer water, sand and plants and kept them in isolation until the environment became suitable for phytoplankton to emerge. [6]
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.

Further experiments to prove that the oxygen developed during the photosynthesis of green plants came from water were performed by Hill in 1937 and 1939. He showed that isolated chloroplasts give off oxygen in the presence of unnatural reducing agents like iron oxalate , ferricyanide or benzoquinone after exposure to light.
