If you can find some concrete wire mesh, you can make taller cages.
I was very jealous as soon as I saw the green houseThe pointy tomatoes are a paste/ sauce tomato called Granadero. Not much moisture in them so great for canning/ less water to cook down for preserving
The beefsteak varieties are Marbone and Ginfizz. All bred specifically for growing in a high tunnel (greenhouse). I'm lucky to have this infrastructure and so long as I can afford to keep the farm I will never grow field tomatoes again. Much easier to control for disease in the greenhouse
