seriously doubted tomato roots grew 10' deep, so I checked, at best
they grow 2' deep and about as wide, with the main portion about 1'
deep, just like most trees.

Redwood trees don't have very deep root systems, especially
considering their height:

Sounds as if you are trying to bonsai tomatoes. I used to use grow bags
to grow mine in, but the roots would grow through the drainage holes in
the bottom, through gaps in the 100 mm (4 in) flooring blocks and into
the soil underneath. Easily 10 inches. I currently use 12 in deep (2
1/2 gallon) buckets, and the roots take up most of the space

So, if I gave you 10" it'd feel like I'm giving you 10'... ya know,
I believe you! LOL
