Hello i have some seed from some of my atlantic giant pumpkins i grew this year. I grew an 80 pounder, 50, 40 and some 30s with this seed. And im sure you could grow a 300 pounder with it. My vines died out early to the squash vine borer and so they would have gotten larger considering by august the vines died. A first year grower of them i still say an 80 pounder was an accomplishment. Well if anyone is interested in some seed i have a bunch available. I also have some speckled swan gourd seeds and some cinderella pumpkin seed all from this years growing. Im looking for some interesting tomatos, watermelons, cantelopes or other melon seed, heirlooms, passiflora edulis large cantelope strain seed, bushel gourds, and check my list for some other things that may interest me. you can always try me i grow a very large assortment of stuff. If you dont have much to trade you can send a sase as well. just send me a email
