A method of containing a floral grouping or potted plant in a sleeve is disclosed. Aspects of the present disclosure provide a switching module used in conjunction with an inductor that is coupled with the switching module. In an embodiment of the invention, the ignitor circuit comprises a voltage-breakover device, a first capacitor, a resistor, a pulse autotransformer, and a second capacitor. The replicated base current is applied to an opposite side of the differential input pair thus the output distortion cancellation circuit creating a deflection of approximately equal magnitude to the reflected base current so as to eliminate the nonlinear differential error signal.
