I've been exploring a lot of the forums lately that I hadn't been on before. This tomato tree caught my eye. Thanks for the welcome. I'll be here more often.
Hello and welcome to the OFH.

I was pretty amazed at this tomato tree also. I think it could be done in a version of the RGGS system with air pruning to promote vigorous growth.
In a grow bag placed in a 5 gallon bucket with holes cut in it for air pruning.
Please let me know if you try it and share pics. I would love to see it done.
