Line 21: Line 21:
 The Eternal Absorption approach completely forgoes Float stage, forcing the controller to stay in Absorption by **setting Vfloat to Vabs**. This addresses the controller issues above.  It will not address the insolation problem on a given day, but extended Absorption will help reduce damage from previous days of poor harvest.  The Eternal Absorption approach completely forgoes Float stage, forcing the controller to stay in Absorption by **setting Vfloat to Vabs**.
