Growin' Upside Down...Hanging Tomato

Have you seen this paid advertisement for a Upside down growing setup for tomatoes? It's says the plant doesnt have to work as hard to receive nutes/ water due to gravity...I'm wondering how this would do with some Ganja? Put a lights on the sides or something (may have water dripping on HID's if it was directly under)...

So, what is everybodys opinion on this?

I'm not planning on doin' it , but someone might want to...

I did that in grade school but i used the sun so they would grow back up

That looks interesting... I might consider doing something like that... but it won't be till next grow -- still 2 mos away.

Yeah. .....I scrog b/c of limited space so I can't use one, but I would sure like to see someone get a successful yield of one of these things.
