Introduction: DIY Aeroponics 6-Plant Tub With Built-in Reservoir
With this aeroponics tub I can grow 6 kale or swiss chard plants in a really small space without having to water them daily. It takes no soil either. I just fill the bottom tub (the built-in reservoir) with about 5 gallons of water and the appropriate nutrients and let it do its thing. I change the water once a week. The roots are sprayed at intervals. Each growing environment is different. The need for experimenting is crucial in receiving a good harvest. Take your time, set your timer 1 minute on and 1 minute off. If no sign of wilting, increase off time for a minute. Continue until desired setting is reached. I like to be 1 minute on and 2 minutes off, for the first 2-4 weeks of vegetative stage. Then move to a 1 minute on and 8 minutes off setting.
UPDATE: After building several of these, I found that using only two 360 degree spray heads in this type of system was enough to keep the root zone moist. As a result of using less spray heads, I was able to use a smaller pump. I also did not need to glue the PVC pieces together.

- Connect one end of the ½" x 10" PVC Risers to the ½" Pattern Plastic Shrub with Plastic Nozzles.
- Connect the other end of the PVC Risers to the threaded side of the 1" x ½" PVC 90-Degree Reducing Elbow Fittings.
- Cut 6 small pieces of the 1" PVC Pipe (about 2½-3 inches each) with a PVC Ratchet Cutter or a Dremel with a cut-off wheel and connect one end to the other end of the 1" x ½" PVC 90-Degree Reducing Elbow Fittings.
- Connect the other end of the 1" PVC Pipe pieces to the 1" PVC Tee Fittings and the 1" PVC Cross Fitting.
- Cut 2 more small pieces of the 1" PVC Pipe (about 2½-3 inches each) and connect them to each non-threaded side of the 1" x 1" x ½" PVC Reducing Tee Fitting. Then connect that piece to one of the 1" PVC Tee Fittings and one end of the 1" PVC Cross Fitting.
- Connect the ½" PVC Barb x MPT Insert Male Adapter to the threaded end of the 1" x 1" x ½" PVC Reducing Tee Fitting.
