May 21, 2015 – AccuWeather reports the upcoming summer will be very warm across much of western and central Canada as the cool weather will be mostly confined to Atlantic Canada.
June 2015 – Greenhouses, with their moist, warm atmospheres, may seem absolutely tropical to many people in late winter, but from the vegetables’ point of view, the proportion of warmth and humidity isn’t always optimal.
June 2015 – Year-round production of greenhouse flowers and vegetables requires heating, lighting and, at times, cooling. All of these things require energy. Efforts have been made since the 1980s to reduce the energy required for greenhouse production.
Mass production of beneficials is an extremely skilful process starting with the establishment of a good stock colony to packaging and shipment of the products.
Research on hydroponics in space might seem like it has little to do with greenhouse production here on Earth, but the work of Dr. Mike Dixon and his colleagues has already led to commercialized products – and more technologies for earthbound greenhouse operators are in the works.

Agriculture has been around a long time, roughly 10,000 years by most accounts. Well-organized agricultural systems can be traced back to the Middle East from about 7,000 years ago.

Recently, I touched on potential challenges for long-term sustainability of intensive mono-crop situations (Inside View, January 2008). However, given immediate market pressures, let’s look at what’s happening with environmental control systems to maximize output and efficiency.
Ruling offers industry some breathing space.  "Growers need to be fully supported in fighting unreasonable standards."
