Input: FRANK LANGFITT  BYLINE:  David Coulter  owns the Inishowen Mushroom farm here. Today a conveyer's loading compost into giant trays where  Coulter  grows  his  mushrooms.
 DAVID COULTER : We grow in these plastic tunnels. They're insulated tunnels. We employ about 34 people.
 COULTER : Well  we're filling today so it's two weeks and three days we will have mushrooms for picking.
LANGFITT: Brexit's still 18 months away  but  Coulter 's mushroom farm is already paying a price. Soon after the Brexit vote  the value of the British pound plunged.
 COULTER : Well  it's been disastrous. Ninety-eight percent of our product goes into the U.K. market.
LANGFITT: Which means  Coulter  earns around 18 percent less for  his  mushrooms because  he 's paid in pounds. The pound fell because investors think leaving the EU's massive market will damage the U.K. economy. Recently Coulter  who's 67  has had to reduce costs. He's laid off workers. His son  Russell  is working up to 18 hours a day  and Coulter has also found a way to save money on compost.
LANGFITT: Back at the mushroom farm in County Donegal  remaining workers are pushing carts of freshly picked mushrooms. The farm produces at least 60 000 pounds a week. I pose a question to  owner David Coulter .
 COULTER : Don't know. I honestly don't know.
