Upside Down Planter?

[AlittleSalt]

I've been making a MS Word document of tomato varieties with info and pictures. I started with what I call, "Small" tomatoes = 3 oz. and under. Today, I'm at Super Sweet 100. I went to http://tatianastomatobase.com/wiki/Super_Sweet_100_F1 Where I read, "Can be used in an "Upside Down" planter with excellent production."

That must be one heck of an upside down planter. SS 100 grows 8 feet tall and 4 feet wide in our garden.

I've seen upside down planters for sale in nearby stores but they were all pretty small in size. I've never planted like this.

I'm wondering if any of you have planted in upside down planters? Is there a good use for this or is it more of a novelty? I know people out here would think it would be interesting - I'm just not sure if it's worth trying?
