Has anyone tried the upside down tomato plant hanger

I haven't personally tried it yet but several of the people on my street have them hanging in their yard. They seem to be growing real well. Of course it is too early yet for them to produce tomatoes but the foliage looks good and healthy.

The idea of hanging tomatoes is a great idea and should work for a lot of things. I am trying to create my own upside down planter. I am using the wire frames from the stands we put around the tomatoes and flowers to keep them standing up when they get to tall. The only thing I can see being a problem is getting them to retain enough water that I only have to water them once a day. I think Perlite with do the trick there. Once I have that working I will try it with strawberries as well.

I"m skeptical as to how big the fruit & plants get. And like you the cost being a waste. There are alternative home made versions you could try, just do a search and see if you can do a homemade one before you invest in a topsey turby.
