Why don't you go to the Container Gardening forum and see what you can find out there? There are many factors that must be taken into account for container growing, particularly on balconies, the soil, the water, the soil heat in the pot, nutrition, drainage, and aeration. That's without any pest or disease damage!

This thread, Container soils and water in containers, has all KINDS of information that might be helpful. Several people who grow tomatoes in containers post in the Container Gardening forum, so maybe their posts will be helpful, too.

Anney,

I read somewhere that your plan was to grow upside down but haven't run across the results.

How'd it go?

Nope, Dave. I ended up giving away my two upside down planters on FreeCycle. I first planted some lettuce in one of those long suspended planters that have holes all over the plastic sides, I think manufactured by the same people, but we had a heavy rainstorm and winds that year. It blew the planter off the hook and crashed it to the ground, splitting the plastic and spilling soil and plants out onto the ground.

Never again. I didn't want to mess with the upside downers for anything. I actually have enough room without them.
