Bower and Nan thank you for the information. I imagined it more simply. I wanted fun for fall and winter, but it would be a lot more work for the spring and summer. And I can not feel it anymore. And the result? Eight years for me too long. On Monday I leave for a holiday in Pilsen. There I will have plenty of time to think about what tomatoes to grow, so it was also fun for me.
