I am a second year grower of giant pumpkins although I have been growing pumkins, gourds etc. for many years. Growing of these giants is a challenging but enjoyable endeavor. I live in north central Ohio about 60 miles north of Columbus.I have learned a great deal from this list which I sure I'll be able to put to use this growing season. After spending much of last summer and fall preparing my garden I hope to grow a 300 pounder if the weather cooperates and I can control the vine borer. But with the Great genetic potential I have obtained from many people on this list I'm hoping for a 400 to 450(maybe). John
