proof of concept system design primarily use a 2 liter bottles I had piling up, as well as create an expandable auto siphon system. thou system could definitely use some fine tuning I do believe it is

    good job with the siphon, perhaps the water is not draining fast enough because of the pipe thickness. I would try increasing the size of the pipe and using coupling to attach the bottles like you have. I would also change the second 90 elbow out of your siphon and use a 45 elbow to increase the speed that the water is dropping.

    I've found the external bell siphon to work much better than the u siphon. All the grow beds in my aquaponics system are connected to an external bell siphon and it drains much better than one bed did with a u siphon.

    LOL, sorry to jump back in again but, just watched your vid again!  Couple of things came to mind after seeing the vid again =)

    1) IF you wanted to "Let your pump work at full capacity" instead of regulating the voltage with a resister/potentiometer .  You can : On your "Inlet Siphon Line" put a "Tee & Valve" inline.  This will allow you to regulate the water level ( Before you siphon kicks in) as seen in the bottles.  As the plants grow ( Roots get longer & allowing for better Aeration ) IF Needed.  Possibly help prevent any type of "Root Rot" issues.

    2) IF you wanted to plant Different Veggies which have Different Growth Rates/ Consumption Needs you can Take it 1 Step further By putting a "Bleed Valve" on each Reservoir.  Then you can have complete control of the individual plants.

    Again Great Idea!

    Peace Out All!

    HAPPY HOLIDAYS my Fellow YouTubers!

    Daniel, I'm not an active YouTuber 1st of all… and I just found this video today 12/19/2014.  This is my first time I'm doing a comment lol.  I like your innovative design and idea.  I don't know if you managed to fix it but, I believe 2 things will allow this system to work the way you want it:

    1) Add a few more "Tee Fittings and Balance Tubes" between your bottles (Side to Side) to make everything as "Parallel".  This will change your system from a "In Line" to a "Synchronized" system.
    2) Increase the diameter of your siphon starting from your "Outlet Line" try doubling the Dia as a starting point to allow more drain volume to flow faster.

    I just started messing with Aeroponics and getting into Aquaponics now myself…. came across your vid because, was looking for siphon ideas for a RO/DI water system today 😉 lol.

    GREAT Idea & Concept!!! Good to see Innovation like yours!  Keep up the good work!  

    Happy Holidays to ALL!

    nice idea, i hope it will not damage the roots because once the nutrients drains out the root will start to fall by gravity the roots will be in constant motion for every cycle.
