This lady Gardener noticed that a neighbour had wonderful red tomatoes. Her tomatoes always stayed green so she asked him how he got such red tomatoes.
He told her his secret that he went to his garden just wearing a mack and then opened the front flashing at them. They always ended up going very red.
The lady gardener thought she would try the same approach and gave her tomatoes a flash.
The next week he asked her if his suggestion was working.
'No' she said 'but my cucumbers have become enormous!'
