The component parts of the system - an Evaposensor and controller - are now available to buy commercially, consultant Chris Burgess told delegates.
"Water stress in cuttings is the most common cause of loss during propagation," he said. "The Evaposensor, with its wet and dry artificial leaves, more accurately mimics what is going on in leaves of the cuttings than existing electronic devices and controllers."
Trials funded by the Horticultural Development Company showed the improved rooting-of-cuttings benefits resulting from better control of mist in their propagation units.
"At New Place Nursery, rooting improved by 4.4 per cent and at Lowaters Nursery by nearly 12 per cent," reported Burgess.
He said the Evaposensor was expected to cost around £150 and the controller around £160. For details, email Chris Burgess.
