Lay out the net pots on the bin lid. Place them so that they cover the lid, but are not closer than 2 inches to each other and are at least 2 inches away from the edges. Mark around them to establish where you will cut your holes. Use the keyhole saw to cut a 2-inch hole at each marked location.
Connect the air line to the pump and the splitter to the air line. Use two additional pieces of air line to connect each one of the air stones to the splitter so that the pump can supply air to both air stones. Place the air stones in the bottom of the bin, arranged to provide as much coverage of the bin area as possible.
Fill the bin almost to the top with water. Add vitamin B1 to the water, mixing it according to the directions on the label. This will help the plants to develop roots. Put the lid on the bin.
Remove the leaves from the lower half of the stems of the plant cuttings. Place one cutting in each net pot. Arrange it so that ½ inch of the cutting sticks out through the bottom of the pot. Fill the pot with clay pellets or silica stones to secure the cutting. Put the pot in a hole in the lid. Repeat until all of the cuttings are in place. Check to make sure the water does not touch the cutting, but is about ½ inch below it.
Program the digital timer to turn on for 15 minutes, then off for 45 minutes around the clock. Plug the pump into the timer and the timer into a power source. The air stones will create bubbles that pop directly under the plants. This will keep your cuttings moist and cause them to develop roots in about 2 weeks.
