I buy tomato seeds for a friend and for my work. They start the plants for me since I'm terrible at it and haven't ever been successful. I so admire the people who can grow strong tomato plants. My friend has a greenhouse and the one at work is climate controlled. I don't mind doing the shopping if they'll do the growing. Actually they were surprised that I offered to source the seeds they couldn't find in stores. I love to shop online so it was a way to repay their kindness.
I moved to the country a few years ago and these old timers around me are all about trading produce and services. I love it!
Kindness is free and brings good karma.
Good luck with the white tomatoes!!
