Nine crops with lisianthus have been carried out on coir in cloth gutters, five of which were also on expanded clay pellets. In addition to growing on a closed system, the use of energy and plant protection products is kept limited. The crops have shown a reasonable production, although not as high as in practice. This difference may be caused by both the frugal exposure to lighting as the unfamiliarity with growing on substrate. The crops on coir have shown a better production than the crops on expanded clay pellets.
