Hi from Milton Keynes, famous for concrete cows and roundabouts. Looking forward to next year so I can reverse my age numbers and be 7 again, seem to remember growing veg from about 5 or 6 but still learning, so, a strange question / thought, I bubble wrap the greenhouse to help keep it warm, how about black plastic or similar round the sides to increase the heat leaving the roof clear for light seems to work when I cover the beds, Like I said a strange one
