    On con struc tion with di men sions 15 � � 5 � � 2 m, con di tions of tem per a ture trans mis sion and veg e ta bles growth are ex am ined. We have been cul ti vat ing pep per, cu cum ber, small cu cum ber, to mato, and lattice. Over ground heat ing has been used, con sist ing of one bent pipe with ra dius of 10 mm, in the shape of hair pin along the both sides of the con struc tion. Un der ground heat ing con-sists of six pipes with ra dius of 20 mm on the depth of 350-400 mm. There have been mea sured the tem per a ture in side con struc tion, the tem per a ture out side con struc tion, the waterflow, and wa ter tem per a ture flow ing into and out of the con struc tion. The ap prox i mate heat ing flow fac tor K is de ter mined by both the equa tion: heat ing bal ance equa tion and ba sic equa tion for tem-per a ture transmission. Veg e ta ble growth has been watch ing dur ing the pe-riod of time from March to No vem ber 2005.
