you will need:
3 milk, water, soda jugs. anything large enough to hold at least a gallon of water (drink some water, save the jug)
1 roll 1/4 inch clear rubber/plastic tubing ($3 for 5 ft, home depot)
1 packet of adjustable irrigation drippers ($3 for 5, home depot)
scissors
total cost for efficient drip system - $6, $9 if you need a water jug
start by cutting the amout of tubing needed to properlly facilitate water flow from the top jug to the dripper. in the bottom of your jug make a hole just large enough for the tub to fit in snugly while preventing water from leaking. then take your dripper and attach it to the free end of the tubing. set the dial/valve about 1-2 drips per 1-2 seconds. take your second jug and cut the bottom out about 6-7 inches high. make a hole in the cut jug in the lower sides again large enough for the tubing but small enough that water doesnt leak. if you have a mesh cage (which you should) make a small hole in the mesh that is close enough for the catch basin. cut another piece of tubing and feed it through the catch basin and mesh into your 3rd and final jug. this will be your overflow catch. you may have to siphon from time to time, but this is what i use for my jackson' and i havent had a problem so far
