Bio-Inferno

Imagine how much money you could save if you could heat your greenhouses with oil derived from sawdust. Great Lakes Greenhouse in Leamington, Ontario, tried it without much extra effort to convert its existing boilers, thanks to the resources and know-how of Dynamotive Energy Systems Corp., based in Vancouver, B.C. Great Lakes Greenhouse, a 1.2-million-square-foot operation that grows seedless cucumbers, ran a four-hour combustion test, burning 2 tons of Dynamotive’s BioOil, a product made from forest and agricultural wastes. The operation, which normally uses Bunker C oil (No. 6 fuel oil), was able to burn the BioOil in its own boilers. According to Andrew Kingston, president and CEO of Dynamotive, further testing will be conducted, but he says the result of the combustion test substituting BioOil for a fossil fuel was encouraging. “During the testing, Dynamotive’s BioOil demonstrated very good ignition properties, steady flame characteristics and a low emissions profile,” […]

A New Way To Bid

Bruce Knox’s first experience with West Auctions’ online capabilities came when he watched the public sale of another grower operation. “I had followed one of their auctions in California,” says Knox, president of Knox Nursery in Florida. “I had one of my truck drivers go to pick up and he said that everything sold. Everything!” Knox decided to use West Auctions when he had to get rid of equipment from his original location that was closing and being consolidated into another facility. He chose an online auction because he didn’t want to limit the number of people who could participate. Roughly 100 companies signed up for the Knox online auction, which improved Bruce’s chances of getting better prices for the equipment.  For The People The beauty of an online auction is the accessibility, says Daniel West, the general manager of West Auctions, Woodland, Calif. Growers have specialized items that only […]

Controller Savings For The Smaller Grower

Many affordable controllers add settings like DIF and night set-back. A controller does not have to be elaborate or complicated to save you money and improve your crop quality. It does not have to control every operation of the greenhouse to be effective. Replacing thermostats with a simple controller that handles only the heating and cooling will save you energy and improve your crops. Many affordable controllers add settings like DIF, night set-back, humidity control and curtain control and still stay price competitive with thermostats.  Single Temperature Reading One of the greatest cost savings that a controller produces versus thermostats is from the coordination of heats and cools from one temperature probe. It is almost universal that growers will tell you that in a greenhouse with thermostats, you will, sooner or later, get heats and cools running at the same time. This can happen when the heat thermostat is located […]

Meeting Irrigation Mandates

Every year, Carroll Brothers Nursery, Clearwater Fla., uses 18 million gallons of water to irrigate its 10 acres using overhead irrigation. The pricetag on that much water per year has jumped from $4,500 to $18,000 between 1991 and 2007, so owner Richard Carroll has been looking for ways to reduce cost. The goal when the gardenia grower first started searching for water alternatives was a second water source – one that would pump and clean water or one that would collect rainwater. "Either way, it was too expensive for a nurseryman to handle," Carroll says. "Knowing I couldn’t touch either of those, I was looking for a way to save water." Drought and water restrictions can cause a grower to rethink irrigation, but so can research. Looking for an irrigation method that would follow BMP practices, as well as provide consistent irrigation, Carroll Brothers did research comparing drip and overhead […]
