The pipes that connect the buckets are oversized,typically 2 inch to 3.the return line back to the epi bucket is usually 3/4So, like a Dutch system but under pressure, forward and Reverse.
I’m not familiar so trying to understand the concept.
I do o know process piping, ,
Head pressure; all pumps have a linear curve that tells ya , how much( volume) and distance said volume can be maintained.
Proper pipe sizing to pump would be key.
Then we get into outlet flow; diffused flow, meaning how much per port are you sending, question does it have a sized port that allows persay limited set volume?
If so then provided one has the correct head and sized pump the flow in theory would be linear to said distance.
Now to get back to my understanding.
This system supplies up top, water percolated down, hits the discharge point and it’s returned to the reservoir under pressure, (pulled)?
Then the question would be how does one calibrate each pot and plants intake? Are they linear to use and flow? Does one adjust flow back via increasing flow in? If so, does this effect/ affect plant growth?
Once it’s back to reservoir, what compensates it’s loss via plant intake?
Because I been thinking about a similar system. Hybred system to ebb and flow setup in daisy chain with flow restrictions to even out flow to the end using single 1/25hp recirc pump, ( head on this would be 60’) so it can run 60 pots set 30x30.
At this point we can agree to disagree for the sake of the OP
For once i agreed with you that your idea would work,Any real benefit is questionable and probably not,But it would work and no the roots would not be any worse off in the first or the last bucket.I dig disagreements and arguments for the sake of finding answers to questions. It's not about confrontation but about pushing one another to find answers for the problems others provide.
Awesome!
That install would result in "NO" Flow. You wouldn't remotely get the running river effect that the undercurrent has been designed to replicate.You could do 500 buckets in a row with a little ass pump it would just take hrs to recirculate the total volume.
lawdAir stones would have to pick up where the flow left off
Only if you was forcing water from 2 inches to 1 inches,BUT nd the magic word here is GRAVITY,the water is being sucked out of the last bucket(Your tank) and being returned to the front of the system,There is nothing more to it.I don't know currents or shit but as a layman it seems that perhaps there might be increased flow at the final bucket in this setup just as it would be on the first bucket of at the front? If you have 2" pipe all the way to a 1" pump isn't this going to cause some sort of vacuum?
But to say taking 2 rows of 12 buckets and turning them into 1 continuous row of 12 would be a drastic change is truly retarded.I personally dont see how this can make any noticible difference in water velocity,Using the same size return pump,If 20 fish tanks are all connected together and there is a pump in the last tank pumping water back to the first tank where does all this velocity and BS come from?There are a lot of factors at play, water volume, velocity, turbulence, gravity, pump placement, resistance, how many corners etc. all of witch influence flow. I'm gonna bow out of breaking these all down for my own sanity. Its far to much calculating for little to no gain of knowledge for anyone.
Every factor affects it... the impact can be large or small and that's why i don't want to bother getting into it. These systems are designed for what their purpose is and any changes are going to be so insignificant its not worth talking about. Take your pump and move it to push the water through instead of pull the water through. Then tell me you don't see a difference. Gravity for instance if you use 2" piping into your chiller and that water chiller is on a table 2' in height that 2"x2' of water... approx 1.2 litres. If its half inch piping it 0.5"x2' of water approx 77ml. Water is approx 8.33 lbs/gal. So in the 2" pipe you have about 2.65 pounds of added head pressure and in the half in pipe you have 0.17lb of added head pressure. This is not taking into account added head pressure from change of direction such as 90 degree corners etc.But to say taking 2 rows of 12 buckets and turning them into 1 continuous row of 12 would be a drastic change is truly retarded.I personally dont see how this can make any noticible difference in water velocity,Using the same size return pump,If 20 fish tanks are all connected together and there is a pump in the last tank pumping water back to the first tank where does all this velocity and BS come from?
If there was a 1 inch pipe connecting them all than the return tank would overfill depending on the size of the pump but what i am saying is undercurrent uses BIG pipes to connect everything so there are no restrictions to increase or decrease head pressure.
