I was referring to the guy in the beginning that said the pump would have to be bigger and the first bucket plant roots would get blasted,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.
So you can call it BS but its real... no matter how insignificant the difference. Thats why i stated in my previous post they key to this is the pump placement. the rest is almost negligible and not worth time or effort explaining or wasting my, yours or others time even looking at.
I did not say anything of the sort about taking 2 rows of buckets and changing them to one row would have a big affect... and I agree with you the affect would be next to nothing
But the reason these systems are effective is because of the negative pressure.All they do is create a void of water displacement.It sucks water from one end and puts it in another
