The ebb/flow table takes extra equipment and maintenance (pump must be on a timer and flood schedule needs to be dialed in).
The res size is much larger.
The res will need to be aerated by an additional piece of equipment, whereas the vertical NFT self- aerates.
If you use net pots, they must be sunk in some substrate or protected from light in some manner. You can use the same pots I used in an ebb n flow though.
There is in fact plumbing for an ebb/flow.
How do I know this stuff? I used to run one. It was fine. My friends run them. They are fine. They have reservoir dumps too- one guy flooded his house with his 40 gallon res. Operator error of course, but you know. Plus the expense of purchasing a large res puts some people off who are looking to try out hydro for the first time with little investment.

I'm not sure what that jab about donkey dicks was all about- do you have a problem with me that I'm not aware of? Where in this thread was Donkey Dick even mentioned?
