Typically, BEB first appears at anthesis and symptoms progress over time. The following are six ideas – based on the energy audits I have done in the Northeast – that may help to slow the electric bill increase. Natural ventilation saves considerable electricity — When compared to fan cooling that operates 2000 to 3,000 hours per year, installing vents saves at least one-quarter on the electric use. Excluding any electricity use for supplemental lighting, a typical new gutter-connect facility will use from 0.50 to 0.75 kilowatt-hours/sq ft/yr whereas a hoophouse range uses from 0.80 – 1.50 kwh/sq ft — year. But when things opened back up in May, it was crazy. Based on electricity use data from audits on several year-round greenhouse operations growing annuals and potted plants, a modern open-roof greenhouse with central boiler and energy/shade screens uses 30% to 50% less electricity than a similar size operation that has hoophouses with fans and individual furnaces or unit heaters. John is an agricultural engineer, an emeritus extension professor at the University of Connecticut and a regular contributor to Greenhouse Management. Finally, the company told him that if he would work the night shift helping with the boilers, they would let him do a little greenhouse work. These are typically installed at about 2 cfm/sq ft of foor area and depending on model use from 0.07 – 0.2 kwhr/1000 sq ft. For 24 hours/day operation this can add another 1.7 – 4.8 kwh/1000 sq ft - day to the greenhouse electric bill but can result in a 2° F – 3° F lowering of the thermostat setting. In the warmer temperatures of the deep south, we generally use chemical than would be used in cooler regions. Bill’s friendly nature and calm demeanor have helped him enact real change for both Kurt Weiss Greenhouses and the industry. We all were a bit concerned in April when there were shutdowns going on and several of our markets were closed off to us. Plants have a wide vase-shaped habit with medium stem strength. jbartok@rcn.com. Better controls provide a better plant environment — upgrading from a thermostat base control system to an electronic system offer many opportunities to reduce electricity consumption. It is slightly less vigorous than Premier Red, and the bract size is smaller than either the red or pink cultivars. Magnesium (Mg) is supplied at high levels in Plantex 18-6-20 Poinsettia Plus (35 ppm Mg at 200 – 250 ppm N) and depending … a> Poinsettia BractEdge Burn: Symptoms and Causes S James E. Barrett, TerriIA. At the age of 10, he was ordering seeds and planting vegetables, and by the time he was 14, he was hauling hundreds of pounds of tomatoes to the local grocery stores to make a little bit of money. The marginal Excess salts can burn poinsettia roots, allowing for Pythium or other fungal pathogens to infect the root system. Bill has no plans to stop anytime soon and retirement is nowhere on the horizon. Centers were small with only a few cyathia. “It’s very easy to get people to follow him versus if you brought somebody in that knew nothing about the industry and didn’t know what it takes,” Kirk says. But Bill doesn’t just keep up with the upper management team. of the growing medium. Apply foliar sprays of calcium chloride dihydrate at 0.5 oz/3 gallons of water, (1 lb per 100 gallons), along with 1/2 teaspoon /gal (8 oz per 100 gallons) of CapSil as a spreading agent. “He’s always impressive that way.”. Bract Edge Burn became a major problem in the late 1970s with the introduction of Gutbier V-14 Glory produced in southern climates. The showy red, pink, white, or bicolored portion of the plant, popularly referred to as the flower, consists of m…
