Twin brothers who spend six hours each day tending to their pumpkins believe they are about to smash a world record by growing one weighing more than 188 stones (1,194kg). Stuart and Ian Paton, 59, use over 150 gallons of water every day to help their gigantic squashes flourish - increasing the weight by over 55lbs every 24 hours at their peak. The British growers said their favourite for this year already weighs more than a tonne at an extraordinary 2,270lbs (162 stone) and has a circumference of 19ft 10 inches after just 87 days of growth. The brothers are the current UK record holders, with a pumpkin they grew last year weighing an impressive 174 stone (2436 lbs). SEE OUR COPY FOR DETAILS ?
