Cut the bottoms off the remaining two bottles. Drill small holes in the bottom pieces, invert and place inside the top pieces as shown.
Remove the "slidey valve thingy" from the detergent bottle cap, revealing the nipple over which we will slide the 3/8 inch tubing (not easy). The cap just happens to be perfect for this and fits securely over the 1 inch pop bottle threads.
Alternatively, any bottle with a nipple cap can be used as the planter itself as long as the tubing can provide a seal over the nipple or the tubing can be fed through an undersized hole in a cap w/o a nipple, also shown.
