Did you find opalka??? I got a big pack of them from tomato growers supply and grew them last year and they were the real deal. I've grown them for 7-8 years now and have always had them be true. They do like it hot and dry!! E-mail me @ tomatoking@zoomtown.com if you still want a few seeds.

Thanks for the offer, Pete, but I was sent some seeds, and I've already started some of them!

Did you have problems with blossom end rot in Opalkas? Apparently a lot of people do. I'm not sure if I can offer them dry weather, more like hot and humid!

I have some!! Blossom end rot is caused by Calcium deficiency not humidity. At least that is my understanding from all that I have read about this problem.
