In order to minimize the losses, the north wall is made opaque with the help of a mirror. Two sets of experiments were performed. First, a modified greenhouse was kept on the ground and another one was kept on the floor covered with a black plastic sheet. The experimental constant C and exponent n are calculated from the experimental data by regression analysis. %8 2014-04-22
