When we talk about growing media, we’re often referring to man-made products that we use in the production of greenhouse crops. We look at what makes a good growing medium; air-filled porosity, cation-exchange capacity, water holding capacity/drainage, weight, the fact that it is “inert,” electrical conductivity and pH, environmental sustainability, and, of course, cost.
Aug. 16, 2011, Peoria, IL — U.S. Department of Agriculture (USDA) scientists are investigating the pest-fighting potential of anthocyanins, healthful chemical compounds in the form of plant pigments that give blueberries, plums, grapes and flowers such as petunias their blue and purple colour.

A significant labour savings potential from a most unlikely source is among the latest buzz from the Greenhouse and Processing Crops Research Centre in Harrow, Ontario.
Though many biocontrol programs for western flower thrips (WFT) in greenhouse vegetables are successful, this pest is often a challenge to manage, particularly when incidence begins early in the season. Part of the challenge lies in the lack of pesticide options that can quickly suppress populations while allowing biocontrol agents to establish a favourable predator/pest ratio. Despite this, many growers are able to successfully manage WFT populations by adhering to two key management recommendations as follows:
Effective and environmentally sound pest management programs do not happen by chance
New” crop pests and diseases regularly cause concern to greenhouse growers.
Clean cuttings, young plants or plugs… this has been a discussion point for many years in our industry.
