What variety of Tomatoes is that ???
If they are not determinate, then you’ll have a serious issue with 8m vines !
Mostly Sungold cherry tomatoes. It was a problem
You need dwarf bushes for a tower.
I’m not doubting you all had trouble with indeterminate vines, especially with that tower. But have you considered going even more dwarf than dwarf? lol. What i mean by that is, have you heard of the MicroTom Tomatoes? Apparently they are not just dwarf, but micro. The result of two pairs of dwarf genes in tandem.
