Has anyone had experience with the hanging tomatos?

Not upside down-- but tomatoes in containers are a challenge already.
Tomatoes like to feed heavily, and like a *steady* supply of *not too
moist* soil.

If you've got even a single square foot of lawn you'd give up, plant
one in the ground, feed it with tomato food, mulch well, and put a
cage around it to keep it aired out. Then pray for hot, humid
weather. Our summers have been so cold the past 3 years I've barely
gotten enough tomatoes for salads-- let alone giving away & making
salsa, & chili sauce.
