Step 3: Making the Water Supply
Let’s make the water reservoir work! First cut several tiny slits in the cork of your bottle. Now insert the water tube and seal the hole with some hot glue. Glue both sides of the cork for the best water insulation. Be careful not to get any glue on the cap threads!
I chose to cut the milk carton in half to make it easier to fill up. You may also cut a couple of holes in the bottom of the bottle/carton so you can hang it up upside down.
Now screw in the cap with the water tube and hang up your water reservoir. You should hang it at a height where the end of the tube dangles slightly over to plants pot.
