When Olson's Greenhouse needed new structures for their plug facility located in Santaquin, Utah, they turned to Conley's Manufacturing, a supplier of greenhouse structures and related equipment manufactured in the USA. "The company had specific needs for these areas, and Conley's structures met those requirements," says Matt Carr, vice president of horticulture at Olson's Greenhouse, in this video below. "We were looking for a greenhouse that met a few criteria, with good air circulation, high side walls to help with heat distribution, high light transmission, and a greenhouse that would eliminate all the drips we saw in the old facility. When we were deciding on the covering, the light transmission was the most important thing to us, versus heat retention, which is why we chose to use polycarbonate."
Olson's Greenhouse, who requested the greenhouse structures, is a 4th generation family-owned and operated business dedicated to providing homeowners and landscapers with locally grown, acclimated bedding plants and related living ornamental plants cultivated over 3.6 million square feet of environmentally controlled greenhouses in Utah, Colorado and Idaho. The company supplies to more than 400 large-scale retail channels in the Western United States through its Wal-Mart, Sam's Club, Home Depot, and Costco distributors.
Conley's Manufacturing, located on 8 acres of land in Montclair, California, provided a greenhouse covering which has an internal retractable sheet system installed to both reduce heat stress during the warmer times of the year and as a thermal barrier to hold the heat inside after the sun sets. The system is controlled by a computer that monitors lightning and temperature sensors to automatically adjust the position of the sheet, while the high side walls help with heat distribution and highlight transmission, and eliminate drips. "One of the features we were most happy with in the greenhouse is the roll form technology. This allows us to not have the drips we had previously because there are many more ways for the water to exit the roof," Carr continues.
Olson's greenhouses also made use of a hot under-bench heating system to ensure consistent temperatures at the root zone, which saves fuel, while its horizontal airflow fans supply heat to the remainder of the greenhouse. The system provides direct heating to plant materials using a tubing material that is integrated directly into the bench frame, and it ensures stable temperatures throughout the growing surface, using hot water from a boiler that can perform at up to 99% efficiency. Because of the materials used, the systems have lower costs than traditional bench-level heating systems, with shorter installation times and a cleaner growing surface.
"As for irrigation, we use a center feed boom system. This allows us to cover the maximum area on the tables, and it also allows us to do any hand watering and touch-up watering that needs to be done directly," says Carr of Olson's.
The 6-foot rolling benches maximize growing space, and they're designed to roll easily, even when fully loaded. Other related equipment includes maxlite linear LEDs to provide supplemental lighting, which can be dimmed, reducing energy costs, and light rails, with very little shadowing on the crops.
