The Future Of Greenhouse Structures

We’re not predicting the end of the Quonset or big gutter-connect ranges. We do, however, believe you will see a dramatic change in the ways some traditional structures work, where greenhouses are built, or even what is considered a “greenhouse” in the future.

LEDs Reduce Costs For Greenhouse Tomato Growers According To Purdue Study

Tomatoes grown around LED lights in the winter can significantly reduce greenhouse energy costs without sacrificing yield, according to a Purdue University study. Cary Mitchell, a professor of horticulture, said the average tomato is shipped about 1,500 miles from warmer climates where they’re grown to cooler climates that cannot produce the fruit cost-effectively in the winter. That journey is costly, however, because tomatoes are picked green and ripen during shipping, decreasing quality and flavor. The lengthy shipping distance also adds to the industry’s carbon footprint. “It makes it really hard for the greenhouse industry to grow tomatoes well in the offseason. We’re trying to change that and make it affordable,” Mitchell said. Energy costs drive up prices for producers who might want to grow tomatoes in greenhouses in states that have winters inhospitable to growing food. Greenhouses must be heated, and shorter, overcast days require costly lighting. Mitchell and doctoral […]

Comparing LED Lighting To High-Pressure Sodium Lamps

Cuttings of vegetatively propagated bedding plants are frequently rooted in late winter and early spring to meet the spring and early summer market demand for flowering bedding plants. However, this is also the time when dirty and old glazing material, interior superstructures, and hanging baskets suspended above benches reduce already seasonally low ambient outdoor daily light integrals (DLIs) inside the greenhouse. Increasing the DLI during propagation has been shown to improve growth and quality of rooted cuttings, as well as reduce time to flower after transplanting. While maintaining clean glazing material, minimizing superstructure and reducing the density of hanging baskets may increase greenhouse DLI, the only way to appreciably increase DLI is to provide supplemental or photosynthetic lighting. Light-emitting diodes (LEDs) are solid-state, semi-conducting diodes that can emit light from ~250 nm to ≥1000 nm. There are several features of LEDs that make them attractive alternatives to high-pressure sodium (HPS) […]
