Step 4Put the pots together
iImage Information

Stick the top pot (the one with the holes in the bottom) into the lower pot (the one with the holes on the sides. They should stick together fairly well without any glue or adhesive. In fact I've made several that I can't pull apart. Make sure you leave about and inch of space in the bottom for the water to drain into. Now you have a top pot that will drain into the lower pot. The water in the lower pot will evaporate up through the plant and out of the holes on the sides.
