Chanelling rain, sun, energy of workers to grow a perfect pepper

Orangeline Farms expanded their 20 acres of double poly greenhouses last year, adding 12 acres under glass. Brothers Jordan and Duffy Kniaziew adopted the latest technology in infrastructure, specifically the capture of rainwater to nourish their peppers and new specialties: strawberries and giant runner beans. Here, Duffy provides a tour of the new complex near Leamington, Ontario. Photos by Glenn Lowson.

KAREN DAVIDSON Leamington, Ontario – For Duffy Kniaziew, greenhouse heaven would be a sunny-side-up day of 23°C and five to 10 millimetres of rain overnight. As president of Orangeline Farms, he sounds strangely reminiscent of a field farmer who wishes for Saturday night rain – seven times over. Along with brother Jordan, vice-president, sales and marketing, they have adopted some of the most advanced technology in the Canadian greenhouse industry. Flexible heating hoses, for example, can be raised higher as the crop moves up trellises. And in the brilliantly lit greenhouse, robotic cars weave silently through the alleys, hauling the pepper harvest to the packing station. Yet, in this carefully calibrated ecosystem, the Kniaziew’s are humble enough to respect rainwater, the ultimate endowment of Mother Nature.

“Rainwater has value to us,” says Duffy Kniaziew (pronounced NA-JEV) who explains that the industry has been challenged lately to meet stricter environmental rules regarding water management. “We decided to research where the best practices were headed and realized that rainwater is an asset. It’s better than well water or municipally-sourced water because it has less sodium and fewer chlorides.” That insight led to a new roof design for the 12 acres of glass greenhouses built last year. Rainfall is channeled into an outside pond with a liner. Several million litres of water can be stored, ready to be pumped indoors into holding tanks. Like any other utility or fuel, backup systems exist to supplement rainwater. While the rainwater is free, the infrastructure to manage this precious resource is not. “There’s no how-to manual for managing these automated systems,” says

Kniaziew. “We’re still learning how to optimize the water while saving more of the nutrient solution.” A tour of the greenhouse reveals investment in PowerBees, automated guided vehicles that follow markers or wires in the floor using lasers for navigation. While these were pioneered in the auto industry, they adapt well to greenhouses with wide pathways where it’s easy to program repetitive routes. “These machines improve the handling of the product,” says Kniaziew. “The speed of the ride can be predetermined for the gentlest travel to cold storage. With a consistent system, we can be more focused on the workers themselves.” European-designed automation may be daunting, but Kniaziew explains that their equipment is monitored by video cameras and the pictures relayed back to global networks for technical diagnosis.
