you put one of those close to the plants

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 Wholesale Led high bay light 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 student Celina experimented with light-emitting diodes, which are cooler and require far less energy than traditional high-pressure sodium lamps used in greenhouses. They got the same yield — size and number of fruit—with high-pressure sodium lamps and LED towers, but the LEDs used about 25 percent of the energy of traditional lamps.The scientists think the method could have other advantages because the cooler LEDs can be placed much closer and along the sides of plants, lighting not only the top, but also the understory.

The leaves are photosynthesizing on the lower parts of the plants, and that may be helping with the plant's energy," GOmez said. "We're getting the high intensity of the Agent of floodlight close to the plants because they're not hot like a high-pressure sodium lamp. If you put one of those close to the plants, you'd scorch it."
