Scientific Research to determine the effectiveness of Reiki energy.
See if Reiki is always on or does it matter if you are wanting or trying to send Reiki. This will require that the 12 plants be divided into 3 groups of 4 each. (or you could do 3 groups of 6 each for 18 plants). Use one group for control, one group will receive passive Reiki (hold and touch but do not try to send Reiki), and one group will receive intentional Reiki for the same amount of time as group two each day.
This experiment has not yet begun.
