This is my second year at growing giant pumpkins and the first that I have had good information, in the form of Don Langevins book and the messages coming in on this page. There is an agricultural fair in my town every year and last year was the first time they had a pumpkin contest. Unfortuneately it is much earlier than most fairs. The contest date is 8\15. I plan on entering one of my babies. Currently I have two pumpkins that I estimate are near 100 pounds each. How much bigger can I expect them to get in the next 19 days if all conditions are optimum? Don Langevin was last years winner with a 412 pounder.
