Fusion

While Fusion mentioned the one source, you can find many commercial seed cos, listing greenhouse types. I've grown TRUST for many years now after a Canadian researcher and consultant stated that 90% of Canadian greenhouse growers grow that variety.

If you look at johnnys seed catalog they will list a number of GH compatable varieties. Other european sources are more noted for best GH performers. You might want to check out COBRA and BUFFALO varieties as popular GH choices.

I've also had very good success with BIG BEEF in my GH growing experiences that span 9 months of the year. It has excellent disease resistance and is well accepted as a flavorful variety.

To answer the other part of your question about taste- Some of the most flavorful tomatoes are grown hydroponically. If you can get a good healthy plant to produce fruit and allow fruit to ripen on the vine then you should have excellent flavor. Accomplishing that goal may be a chalenge in the middle of winter.
