Farmers already often rely on commercial bees to encourage pollination and maximise fruiting for both indoor and outdoor farming. For example, the almond industry, of which 85% is based in California"s Central Valley, depends on billions of honey bees that are shipped tens of thousands of miles to and from Florida to pollinate the almond blossoms each year. The hives are brought in on trucks and the bees are released into each grove before being moved on to the next farm. In the UK, strawberries grown in polytunnels are also pollinated with commercial honey bees – though, curiously, pollination by wild bees results in larger fruits.
