OK so I am looking to build an aero system that hangs off the edge of my deck... this is actually not for growing bud so dont worry about security. Anyway, I want to use a 20 ft piece of 6inch diameter PVC and drill 18 4inch holes for the pots... I know I need the reservoir and water pump and tubing to run up into the pvc... I am just unfamiliar with what i need to make the ring on the inside with all the sprayers... Ive looked at guides but none seem to give any depth on the construction of this component... and does anyone know how powerful a water pump i need if the plants are going to be a good 6 ft from the reservoir? any advice is much appreciated
