Periodically check nozzles for plugged orifices. Some form of automatic control is essential to prevent excessive use of water and detrimental growth effects due to over-watering which occurs with continuous misting. Since as many as 20 on-off cycles may be necessary per hour, manual control is impractical. Lastly, despite the ideal environment a mist bench system provides, rooting powder or quick dip hormone solutions may be necessary for species that are difficult to root. Hardening-off Cuttings Tender cuttings will be shocked if not carefully removed from a moist, humid environment to a dryer setting.
Some nurseries allow cuttings to root into the soil beneath the rooting medium.
The mist frame is removed altogether. Root cuttings in small containers arranged in flats under mist. Plants can then be transplanted with little stress. Block-type rooting mediums are routinely used such as oasis cubes and rockwool cubes. Pot up cuttings and move them to a shaded, humid location, gradually increasing sunlight and decreasing watering intervals.
