In a method for epitaxially growing objects of SiC, a Group III-nitride or alloys thereof on a substrate (13) received in a susceptor (7) having circumferential walls (8) these walls and by that the substrate and a source material (24) for the growth are heated above a temperature level from which sublimation of the material grown starts to increase considerably. The carrier gas flow is fed into the susceptor towards the substrate for carrying said source material to the substrate for said growth. At least a part of said source material for said growth is added to the carrier gas flow upstream the susceptor (7) and carried by the carrier gas flow to the susceptor in one of a) a solid state and b) a liquid state for being brought to a vapor state in a container comprising said susceptor by said heating and carried in a vapor state to said substrate for said growth.
