1. The Ascending PeriodDuring the ASCENDING period there exists a greateremphasis on the energy flow from the centre of the Earth tothe cosmic periphery. This phenomenon, observed in springtides, has a correspondence to the strength of the sap flow in aplant that can be harnessed by the gardener.2. The Descending PeriodDuring the DESCENDING period the lunar energy tends toflow down from the cosmic periphery towards the centre ofthe Earth. These forces are now biased to work more stronglyinto the lower reaches of the plant (everything that is in thesoil).
