Allegro Acres to expand greenhouse pepper acreage under LEDs April 21, 2021 Photo courtesy of Allegro Acres. Allegro Acres is expanding its acreage of LED-lit greenhouse peppers from four to 12 acres for winter production. The first of its kind to take place on a commercial-scale in Canada, the initial four acres of greenhouse LEDs were installed in 2020 and produced a successful crop of peppers this past winter. According to the President of Allegro Acres, Gene Ingratta, Allegro will be installing additional LEDs this summer, in time for use in early October. Allegro will also be implementing light abatement measures to comply with greenhouse lighting bylaws announced in the municipality late last year, as well as a high pressure misting system to help control temperature and humidity.
