Improving the quality and success rate of propagation. LED lights will be used a great deal more for both our motherstock and propagation in the future.
Not only are we seeing quality improved, I am able to program our buying-in of unrooted cuttings with greater certainty, knowing that we can supply plugs to our customers exactly when they require them.– Bruce Harnett, Kernock Park Plants
The right lighting
In 2011, trials started with LED lighting – with various light spectra – on propagated material. This small-scale trial provided sufficient encouragement to conduct a larger trial over propagation beds using 84% red light from Philips GreenPower LED production modules. GreenPower LED production modules offer increased control, improved and uniform crop quality, and energy savings of up to 75%.
The results were so positive that it was clear more trials should be held. In 2014, Philips was approached for advice on the way forward, including its then-new GreenPower LED toplighting modules. Delivering light levels typically ranging from 40-300 μmol/m2/s in a highly efficient way, GreenPower LED toplighting offers considerable opportunities to increase production and improve crop quality during the year.
The results with varieties known to be difficult to propagate were a revelation. In addition to a vastly improved success rate, in some cases it went from 30% to 96%. The rooting was quicker and Botrytis control was limited to just one preventative spray.
