T.C. Jayalath, PhD student and technician in the lab, won the 2021 Controlled Environment graduate student competition at the 2021 ASHS meeting in Denver. His presentation focused on the concept of ‘carry-over DLI’, an idea developed in our lab that takes advantage of sunny days, by lowering the target daily light integral the day after a sunny day. He was able to show in growth chamber and greenhouse studies, that this carrying over of ‘excess’ DLI (up to 5 – 7 mol/m2/d) does not reduce growth of lettuce. But it can save greenhouse growers about $6,000 – $7,000/acre/year. Congrats, T.C. on a job well done! Great research and a great presentation!
