Could anyone tell me where I can buy a small circular plastic air vent for a small polythene greenhouse/cloche that I have just made.6x4 ft x 2 ft 9 inch high.I intend fitting them in the ends of the greenhouse

Try Rytons building products, they have more vents and louvres than you could shake a stick at.
