Summary Common/standard 100 mm / 104 mm diameters PVC tube. Total lenght : 605 mm Purpose : conception of hydroponic systems... I cannot find it online so I try to make it. Please feel free to tell me if there is anything wrong. I'm particulary worried about the junction between the 100 mm and the 104 mm.

With a rule I took the more accurate measures possible.
