hydroponic concept and materials

This is my concept so far i haven't decided how i'm going to set it up yet

My materials are as follows
i think it was a 10 ft Rain Master 2 in. x 3 in. Vinyl Downspout... cut down into 3 long pieces X2 with a total of 6 pieces

This one has a small side that goes inside of the downspout and a large opening that goes over the other downspout piece.. i placed the larger piece on the one on top and the small one on the bottom to prevent leaks... this is a crucial step

i then sealed it with silicone and duck tape... you can use black or white.. i used black but then covered with white for appearance purposes

i'm using dixie plastic cups.. they require a 3 inch hole and i used a 3 inch hole saw.. The cups are bit big but ithink it might be good since i be able to grow bigger plants.. i don't know how is going to work out.. but i seen people use smaller cups in other set ups

i drilled 3 holes at the bottom of each cup

i'm using some roofing metal net and some plastic pieces to hold this up.. and some zippy ties. but i dont think this is going to be my last set up.. i might change it later on
