Anybody heard of this or tried it before?

I have never heard of that. It is a really interesting idea. I am not sure how well it will work though. A plant usually grows up towards a light source. Since the tomato plants are coming out of the bottom, you would think they are supposed to grow down. But as the sun hits the plant, it will try to stretch toward the light. I think it might curl around the planter! Even if it does do that and looks a little bit funny, as long as it still produces fruit, I guess it doesnt matter! I hope this works out for you to bring you a bit of comfort while you help your son heal.

I hope this does work for you. I've been wanting to try it for a long time so I'm looking forward to you posting the outcome!

Wow... this is a very interesting idea to me... especially since I have an empty planter exactly like that one, waiting in my back yard for planting season here. I'm wondering about that quantity of soil being rich enough to sustain multiple fruit-bearing plants. Normally, I only have annual flowers in a pot of that size. I did a little research, though, and it seems to be a very viable concept. Here is something called a "topsy turvy" planter -- it does state that plants will curve upward toward the light, as someone already mentioned, but this site says that just makes them all the more interesting... http://www.cleanairgardening.com/totuupdotofl.html Good luck with it... I might just have to give this a go myself! :) It's certainly a nice alternative to constant weeding or having to routinely stake or tie up tomato plants! Thanks for sharing! My best wishes to your son, and strength to you both, for a full recovery from his accident.

I don't know what are you trying to say. Sometime discription may make confusion hard to get it.
