I built this 5 gallon bucket aeroponic propagator to root my cuttings and clones quickly. This is a simple construction that is very effective I hope you find it helpful, fun and interesting.
Step 1: The Materials
The materials are Really simple for this project. A 5 gallon bucket with a lid, a small fountain pump, 110v timer for the pump, some 2" plastic cups from a aquaponics supplier (I got mine from Amazon for cheap) along with the small 2" foam disc for the aquaponics cups... Again pennies.
Step 2: Assemble the Pump and Spray Head
The small fountain pump comes with several different sized fittings, I was able to use one that fir the spray head diameter perfectly. It was a reducer to 1/4" hose and a 1/4" firing adapter. Easy and worked great. When the timer turns the pump on the circle spray head mists all of the stems and soon roots of your clone cuttings.
Step 3: The Lid Assembly and Propagation Cuts and Supports.
Drill equally spaced holes the size of your plastic cups and inset them with the foam disc to support your cuttings. Make sure enough of your cuttings sit below the lid in the stream/mist of the pump and that they get moisture 2-3 times a day for about an hour... This seems to work well with green soft cuttings of plants.
Step 4: Assembled and Growing
These are cuttings from some simple house plants as a test and in a matter of about 5 days they were all already showing signs of root growth. This is a great easy project with a great return on investment. I hope you enjoy it.
