Big Max Organic Pumpkin Seeds. Big Max lives up to its name by producing large, exhibition sized pumpkins averaging 45 kg (100 lbs) in weight and measuring up 175 cm (70″) in diameter. Of course there is only one use for these brutes – carving them into extra large Jack ‘o Lanterns that can be seen for miles. The nearly round pumpkins have thick, slight red-orange skin with bright yellow-orange flesh. The flesh itself is also used in canning and for freezing.
