Planting three tomato plants in one grow bag creates a mess, although the self-watering boxes are prepared for three plants having three internal tubes reaching down into the water.
When you’re dealing with cucumber plants it’s even too much with two plants in each grow bag:

What an awesome blog! Simple, uncluttered and highly informative. Great job! Stumbling it right now.
Thank you Liz for your kind words and the stumble!
