I would like to build a 4 site “fallponic” system like the one on YouTube by Gary at PAHydroponics. After looking at his design I noticed a couple things I could change that would save some money on fittings as well as time to build and reducing possible leak sites. The diagram on the left is my idea and the one on the right is Gary’s. Green lines are water input, blue lines are 3” returns to the reservoir and pump which is yellow. As the flow of water is determined or restricted if you will, by the size of the pipe entering the reservoir I see no reason the system on the left wouldn’t work equally as well and at the same time reducing on some expensive fittings.
Is my logic correct or have I over medicated ?
