The Lost Gardens of Heligon in Cornwall Still Grow Pineapples in the Old Fashion Way

You can use horse urin to grow pineapples really, which they do at the lost gardens of helegon. And this, they still make pineapples in the old way that they used to. They heat up the greenhouse by putting horse manure and horse urine and piles of straw in the corner. Will get hotter and hotter, and that heats up the building. But it does mean every pineapple cost one thousand, 200 pounds to grow tas t. So it's a lot of money for one pineapple, isn't it?
