Mine is trying to grow tomato plants in much smaller containers than usual but with drip irrigation that will be set to cycle on for 10-15 minutes several times per day. These 23 plants would have been tossed as excess, as all of my normal planting areas are occupied. So far these in the containers look better than most of my in ground plants. I'm thinking that they also may be less prone to disease, but time will tell. This first link is a short video of the planting arrangement and that is followed by a few detail photos.
Each plant gets a drip emitter like the one below:
Here are a few photos of fruit set.
