Bob Clelland, retired janitor of Tranent Primary, kindly offered to help the eco committee to build a plastic bottle greenhouse. He masterminded the design and worked with different groups of children to complete it. All the children brought in 2 litre plastic bottles, nearly 1800 of them, and under Bob’s guidance cut them to the required size. The children then put the bottles onto canes and fixed them to the framework. The whole project only took 4 weeks thanks to Bob.
