hey there earl i was looking at ur post with the aeroponics setup i was thinking about building a system just like that with a slight diff. I was going to use the same 4" pvc pipe but was going to insert a 1/2" pipe inside the 4" which would run the sprayers connected to the 1/2" pipe and I am going to put 10 3" net pots in a 7 foot piece of 4" pipe. I am going to have 6 pipes in total with a 45 gallon resievor with a 1054 gph sub. pump. Each net pot will be 4.5" apart from one another. Do you think that will be good enough to support cutting thru mature harvest
