Ok its been something like three weeks and my upside-down tomatoes continue to live. They are trying to grow upwards towards the sun but that problem should remedy its self as soon as they set fruit. For now I'm letting the drip irrigation system water them daily. In fact the only thing I've done since panting them has been to add more soil to their baskets to make sure their roots have plenty of room to grow.
Not a lot of work but so far not a lot of tomatoes either. I'll keep you updated as the project progresses but I'm signing off for now.
