You asked and we posted!!!

This vid shows the hydrolic/pneumatic mechanics behind the system! Very easy, very cheap!!

  • When the timer is on for an hour does it automatically drain when the timer goes off?

    Do you have to be physically present to turn the air-line relief valve for it to drain?

    Congrats on the great, simple, easy, design.

  • @TheSdveg Yes, it should automatically drain. No need to be standing there. You should play with the relief valve when setting it up, it should act as a 'leak in the line' so-to-speak: it will let off enough air to allow the pressure to drain when the pump is off, but not too much open, where the system cannot pressurize when the pump is on...its a bit of fine tuning, but not impossible. Because its a small leak, it cant take up to 15 mins to drain, but thats still OK!

  • why cant u leave it flooded? the roots already have oxygen

  • @gamz1993 You could, but then it would be a "bubbleponic" system, it has the advantage of being simple and convenient; the ebb and flow has the advantage of mimicking nature better.

  • @Dooobs My bad! I did a bunch of videos about this system; im sure i missed other things too!

  • @SurfMonkeyCoconut

    I figured there must be, however you don't mention it =O! You mention that the system needs to flood and drain but not that the pump needs to be on a timer/how long to run it for. Either way its pretty obvious that the pump cant be run always so I doubt anyone would. I'm just being annoying, so ignore me and carry on with your great videos sir.

  • Interesting vid! I´m Also into Diy hydroponic systems testing for some time now. Its somekind kind of flood and drain system i think. it uses the air to also pump the water. Air is always good in the solution, but i dont like the air pump noise. At the moment im into getting air in the water just using the water(room fountain) pumps playing with venturi effect a.s.o.... If u compare both they are much more quiet and u can get nice fine bubbles.

    Realy good vid an explanation! Thx for sharing!

  • could you do less water and use bubbleponic system and leave the the pump on with an air stone in the bottom? not fancy timing or overflowing!

  • @Dooobs LOL! there IS a timer on this system! I believe i mentioned it should only flood about 4 times a day for 15-30 minutes. Later when the plant grows it will need to be flooded up to every 45 mins depending on the plants needs.
