Step 4The hole template
Now that we know what we want to achieve, lets start building!
Make a template
Get a plastic cup, and line it up to the end of one of your PVC pipes.
Choose how deep you want the cup to go.
Don't have it sitting in the water level, leave it a little above the bottom, don't worry, the roots know how to find water.
Mark the point onto the cup.
Cut the cup along the line you marked.
Get a scrap of cardboard, and draw a line around the cut off cup (the top part).
Cut out the hole, and test it with a new cup, to make sure it fits, and is at the height you want.
Work out how many cups you want in your pipe (I picked 10 for two pipes, and 3 for the other two).
As my pipes were 1 metre long (~3 feet), I centred my templates around a 10 centimetre (4 inches), and made a small whole on each side of the big hole.
The two small wholes give you an easy way to make sure each cup is spaced evenly apart from each other.
