Improving the quality and success rate of propagation

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.

The challenge

With a catalogue of nearly 1200 varieties, ranging from annuals to nursery stock, plus a further 400 varieties in trial, the challenge is to propagate all plants successfully. The production material comes from motherstock from the nursery, or is brought in as unrooted cuttings – tissue culture – from a number of sources, or from seed.

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.
