This is part 3 of my newer version low-pressure aeroponic system, which shows the final assembly, setup and progress after 2 1/2 months.

Last year I made a video (https://youtu.be/fBcNxiv4Pc0) of a DIY low-pressure aeroponics system design (aka sprayapoincs or soakaponics), which uses a submersible pump and PVC with spray nozzles attached. The nozzles spray nutrient solution onto the roots, then circulate back through the pump. That design worked very well, but there were a few issues I encountered.
Problems with old version:
1. Small reservoir
2. Difficult to change nutrients
3. Over-complicated design, requiring special tools
The new design addresses these issues. If you built the other version, you probably have most of the parts already.
I did not mention in the video, but for the nutrient solution, I used a three part mix of Masterblend, Magnesium Sulfate and Calcium Nitrate at a ppm of around 850.
Part 1 of this tutorial shows the parts needed and preparation. Part 2 shows the construction, and Part 3 shows the final assembly, operation and follow-up.
Parts needed for this system as shown in the video:
PVC parts
sched 40 1/2″ PVC pipe –
3 x 1″ long pieces
1 x 7/8″ long piece
2 x 3″ long pieces
2 x 1/2″ couplers
2 x 1/2″ caps
2 x 1/2″ slip 45 degree elbows
1 x 90 deg tee
1 x 1/2″ adapter threaded/slip (screws into the pump) – get at a Lowes or Home Depot
3 x Spray nozzles and 11/64″ drill bit – https://goo.gl/QX4u9j
Submersible pump
1 x EcoPlus 728310 Eco 396 Submersible Pump, 396GPH http://goo.gl/n4cmuL (I mentioned in the video that I had seen one by Apollo Horticulture for 10.00, but don’t see that available at the time of this posting.)
Drill bits for internal bucket – These don’t have to be exact, the 11/16″ is what I used. It needs to be either exactly the diameter of the 1/2″ PVC pipe or just under.
1/4″
11/16″
2 x 5 gallon buckets – https://goo.gl/qUS06c (You can get these cheaper at big box stores)
1 x 5 gallon bucket lid Approx. 2.00 in box stores
1 x 3″ net pot https://goo.gl/NUZKIu
1 x 3″ hole saw – https://goo.gl/TPehGL
OR
*You might want to modify this design using a 6 inch bucket lid net pot. That would offer a little more stability and save some work and money. (6 inch net pot – https://goo.gl/8nlTAS) If you use this you won’t need the regular bucket lid, 3 inch net pot or 3 inch hole saw.
Supporting media
Clay pebbles/hydroton – https://goo.gl/pKFvKk
*alternately you could use coco coir chips instead – https://goo.gl/q5k8Dl
Power cord management
1 x 1 7/8″ hole saw – https://goo.gl/dRz3GN
1 x 2″ neoprene cloning collar – https://goo.gl/sb3bMe (This also has the spray nozzles needed, listed above, but doesn’t included the 11/64″ bit)

another idea that may be helpful for trans planting is cut the bottom of the net cup you have attached to your bucket then have the plant already started in one net cup so you can drop those roots down easier with no damage.
Is it better to have the droplets that big or to have it spray a fine mist?
I like this the best of all three video updates on your system. Good idea to show plant growth and results alongside system design and function. Good job Peter!
make a rack over head of the plant or plants and run strings down to the plant for support. easier to do
Personally I don't like blu and red only led light, but great great job man! I'll follow! Thanks for sharing!
you can make money by becoming an amazon affiliate and using affiliate links for the parts you're gonna be using.
Those roots just blew me away. I knew there would be some but to that extent! Very nice, looking forward to seeing how well it fruits.
Nice results Peter! Have you harvested many pods off of it? Thanks for sharing.
