David--that sounds like an amazing project. It's awesome you have that greenhouse space to grow in. We are all home gardeners, starting plants under grow lights and praying our weather is good enough to get them out at the appropriate time.
How have your grafted tomatoes done?
We tried selling some of the new dwarf varieties this year, but they just were not that popular. I grew out a few in my garden, and they were very prolific, but didn't love the taste. But they were nice, bushy, hardy plants.
