The present paper aims to outline problems for growing healthy plants over a complete ontogenetic cycle in space farming. Possible effects of sub-gravity or microgravity conditions on suppression of plant growth and reproduction were summarized in a view of heat and gas exchanges between leaves and reproductive organs of plants and atmosphere. It is concluded that proper control of air movement would be essential to make the environmental variables uniform inside the plant canopy and to enhance the heat/gas exchange between plants and the ambient air and thus promote growth of healthy plants under microgravity conditions in space farming.
