How vine crop growers can reduce waste and labor cost and prevent virus transmission

Hort Americas and Agrifast see the Tomsystem as a simple but elegant piece of agtech that addresses two major issues vine crop greenhouse growers are facing today: labor and sustainability. The Tomsystem replaces traditional crop-supporting methods. Besides the sustainability benefits, the process also lowers the labor cost per hectare, providing the grower a significant net economic gain.

NC State’s Collado and Hernandez Research Cannabis Water Use Under Supplemental Light

North Carolina State University researchers Professor Ricardo Hernandez and Cristian Collado worked with Current’s Arize® Element L1000 LED top lighting in a greenhouse setting to explore the impact of light levels on the production of cuttings, plant growth, flower production, quality, and water use of a cannabis sativa variety commonly cultivated for its high levels of CBD. The impact of different levels of light throughout the vegetative and reproductive phases of growth was isolated by controlling all other environmental factors, such as temperature, fertigation, CO2, and water usage.

Tip Burn and Calcium Deficiency

Tip burn can be a common problem in lettuce greenhouses. Tip burn is characterized by the presence of necrotic tissue at the growing area of lettuce. This symptom is a consequence of calcium deficiency. Calcium is required to build cell walls. When Calcium is deficient, new cells tend to die due to the lack of calcium to build up the cell wall.
