Growing tomatoes....

I've heard really good things about this device. But haven't been able to get one since they are always sold out. Now they are available and we are too deep into the summer to plant...oh well.

I'm thinking about ordering a couple of these for next year, but was wondering if anyone here has ever use one of these?? I've got no affiliation with these guys...but it just looks like a cool idea

What happens when you water the plant? And how do the roots know to grow upwards? Or are they started normally, then inverted.
