In the same way one does not need to know the precise histological process by which callus forms to remove it, one does not need to know every detail of how a pathological force came to happen to counter it.
After choosing, the experiment was repeated with the four best callus inductor media (CIM), which were called M1, M2, M3, and M4, and subsequently distributed between the different light qualities (white, blue, red, and dark), in the BIM medium for 40 days and 16 hours photoperiod at 25[degrees]C [+ or -] 2.
