I was recently told i could make a metal pipe from brass fittings and other hardware parts. However i can't find any instruction on how to go about constructing one. If you can leave a link or if you know from experience, anything will help.
Awhile back someone asked about the main pieces and instructions on setting up a hydroponic system. I was wondering why the Q was never answered, and would also like to know the cheapest way to make a hydro system with instructions on setting it up.
