CDEVIDAL,
I missed one of your statements earlier.
I have not grown heirlooms in greenhouses before, so maybe someone else can answer that. However, I have seen some research regarding experiments and productivity results from trials of different varieties grown in greenhouses. Maybe you can research this. I can't recall for sure, but I do not think that Brandywine is a good choice for greenhouses.
Perhaps you can seek out other greenhouse tomato growers/ organic farmers in your specific area and find out what they grow. Florida Organic Growers would be a good network of folks if you are thinking of growing organically.
