Low cost mist bioreactors were designed to grow Artemisia annua transformed roots and Dianthus caryophyllus shoots. The reactors use similar mist generators but the culture chambers were modified to meet the requirements of each application. For root cultures grown in the mist reactor, the ratio of the final to initial fresh weight was 7.4 after 24 days while for the shoots, the ratio was 10.8 after 14 days. Shoots grown in the mist had about half the hyperhydration of the controls grown in culture tubes.
