What do you think about vertical hydro systems? Maybe somebody have experience with these systems? I'm very interested....It's worth to build one?

The normal 4 in street "Y" pvc drain street y work great
Using a pump system to the top and net pots, hydrocorn.
8 45 degree
8 "t"s
36 street "y"s
350- 700 gpm pump
50 ft of 3/8 hose T and Y fittings
a 1000 watt mh or hps
and you have a normal vertical grow
But use caution the federal law comes in to play with over 99 plants.
Growing is fun for all, in nobody knows your growing.

I'm planing to build one.I would like to build something like "cage" vertical chamber fully izolated from enviroment with its own micro climate. Do I need a some kind nozzle on the top of the pot or just let the water simple flow down like on NFT?
