Earth & Grow devices were used on multiple species of plants in a student’s independent study at a local university. This post focuses on Coleus plants which were one of the many exciting results from the experiment. Below are a few pictures of identical Coleus plants dating from December 13th to March 2nd. The Coleus on the right was plugged in using an Earth & Grow prototype.
In these pictures observe how the Earth & Grow device enhanced the plant’s branching, undergrowth, vitality, and color!
These pepper plants were grown under a sky light in a poorly ventilated garage last summer. Day time temperatures averaged over 85 degrees. The plant that was plugged in using Earth & Grow grew much healthier, producing more branches and dozens more flowers than the control, while showing little if any signs of heat stress throughout the 8 weeks.
The pepper plant that was not connected to the Earth was clearly affected by the heat and lack of air flow in the garage. It produced dull, wilted leaves and stunted growth. This experiment clearly demonstrates the benefits of reconnecting a plant to the Earth when grown in an indoor environment.
In a new study, scientists have found a cabbage relative capable of remembering and responding to information. Plants are able to remember information and react to it, thanks to an internal communications system that can be likened to a central nervous system in animals, according to a new study by a Polish plant biologist.
Plants “remember” information about light, and a certain type of cell transmits that information, much like nerves do in animals.
In the study, which was published in the early online version of the journal Plant Cells July 16, the researchers found that light shone on one leaf of an Arabidopsis thaliana plant caused the whole plant to respond. The response lasted even after the light source was taken away, suggesting the plant remembered the light input.
“The signaling continues after the light is off; it is building short-term memory,” said the lead author, Stanislaw Karpinski, in an e-mail message. “The leaves are able to physiologically ‘memorize’ different excess light episodes and use this stored information, for example, for improving their acclimation and immune defenses.”
