How to make an inexpensive low-pressure aeroponics system - Improved version - Part 2

This is part 2 of my newer version low-pressure aeroponic system, which covers most of the actual construction.
Last year I made a video ( • How to make an inexpen... ) 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 - goo.gl/QX4u9j
Submersible pump
1 x EcoPlus 728310 Eco 396 Submersible Pump, 396GPH 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 - 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 goo.gl/NUZKIu
1 x 3" hole saw - 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 - 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 - goo.gl/pKFvKk
*alternately you could use coco coir chips instead - goo.gl/q5k8Dl
Power cord management
1 x 1 7/8" hole saw - goo.gl/dRz3GN
1 x 2" neoprene cloning collar - goo.gl/sb3bMe (This also has the spray nozzles needed, listed above, but doesn't included the 11/64" bit)

Great stuff! In my head i was trying to think about how to do an aeroponic system where the water drains to a reservoir DIRECTLY BENEATH it, you may have just solved my problem. Also, a de-burring tool is something that would make clearing the bucket holes much easier.

Thanks, for watching! I agree, a deburring tool would be great.

There are a couple things I want to mention about this. I said in the first part, but should have captioned, or mentioned here that I was using a 11/64" bit for installing the spray nozzles. Also, a good alternative to the 3 inch net pot mounted in the regular bucket lid would but to just use a 6 inch net pot bucket lid. This would be easier to do, provide a little better support and probably encourage more root growth. The 3 inch one is working fine, but if I could redo it I'd use the 6 inch net pot.

Seems like quite an elaborate system and expense for just one net pot. Most similar projects like this use the same amount of equipment, but are used with 8-24 net pots . . .

Thanks, for watching. It's more proof of concept, you could adapt, change, expand on it.
