Petri dish design. Figure 1a illustrates the Petri dish cut in half with the agar on each side cut into the design to guide the mycelium across the agar gap in the center of the dish. Figure 1b depicts the Petri dish reassembled with spacers and rubber bands in place. Figure 1c represents the second method for reassembling the Petri dish using duct tape. Figure 1c also illustrates how the MycoGrow inoculant appeared on the agar after application.
