Grafting is a horticultural technology that combines two plants, the scion and the rootsock, to create a plant with desirable features from both parts. In the United States the use of vegetable grafting in field production remains limited, although 70% of the total hydroponic greenhouse tomato area uses grafted seedlings. Large, commercial grafting operations use controlled-environment growth chambers, but the high cost limits their use in most small-scale grafting operations. Healing chambers are an alternative solution that provides proper healing at a lower cost for growers and researchers.
